Visit the PubMed ArticleWe tested whether BL-binding activates BRI1's kinase. Receptor activation often involves auto-phosphorylation, which can lead to a change of mobility in SDS–polyacrylamide gel electrophoresis (PAGE). Arabidopsis seedlings grown in the presence of the BR biosynthetic inhibitor brassinazole were treated with BL and analysed by immunoblotting (Fig. 3). Treatment of wild-type seedlings with 1 microM BL for 1 h caused a shift of BRI1 from a faster to a slower migrating band, compared with an untreated sample or a sample treated with mock solution (Fig. 3a). Phosphatase treatment of the BL-treated samples shifted the slower band back to the fast migrating band, suggesting that the shift of mobility represents BRI1 phosphorylation (Fig. 3b). We also observed such a BL-induced BRI1 mobility shift in the BL biosynthetic mutant det2, but not in the bri1-117 mutant (Fig. 3c), which contains a mutation that abolishes BRI1's in vitro kinase activity (data not shown). Our data indicate that BL induction of BRI1 phosphorylation requires the kinase activity of BRI1, suggesting that BL-binding induces autophosphorylation of BRI1

Visit the PubMed ArticleTo analyze the efficiency of their degradation in the mutant, we monitored the stability of a AXR3/IAA17-GUS reporter protein that was expressed under the control of a heat-shock promoter (HS::AXR3NT-GUS) (Gray et al., 2001). In 36-hour-old seedlings of the wild type and the mutant, GUS stains were observed immediately after heat-shock induction, with the mutant staining rather more intensely than the wild type (Fig. 8A,B). At 60 minutes after the heat shock period, although GUS staining disappeared in wild-type seedlings, it was still observed in the hlr mutant (Fig. 8C,D). Increased stability was observed in the wild type when a proteasome inhibitor, MG132, was added to the seedlings (Fig. 8E). Furthermore, stability was increased in both the wild type and the mutant when we used another marker protein, axr3-1NT-GUS (Gray et al., 2001), which has a mutation in the domain responsible for its degradation (data not shown). These results suggest that the mutation in the HLR gene stabilizes the AUX/IAA proteins, and that the HLR gene is required for proteasome activity in the post-embryonic meristem

Visit the PubMed ArticleMass spectrometry analysis of histone H4 methylated by PHRMT5 revealed that methylation occurred at histone H4R3 in both mono- and dimethylated manners based on the peptide corresponding to the first five amino acids of histone H4
Pei Y, Niu L, Lu F, Liu C, Zhai J, Kong X, Cao X - Mutations in the Type II protein arginine methyltransferase AtPRMT5 result in pleiotropic developmental defects in Arabidopsis
Visit the PubMed ArticleTo substantiate the methyltransferase activity of AtPRMT5, recombinant glutathione S-transferase (GST)-AtPRMT5 fusion protein was analyzed. Figure 3A showed both Coomassie blue-stained gels (a and c) and autoradiographs (b and d) of the proteins methylated in the reactions. Among the four core histones (H2A, H2B, H3, and H4) assayed, H4 was preferentially methylated and H2A was also methylated in vitro (Fig. 3A, b). In addition to histones, nonhistone protein MBP was also the substrate of AtPRMT5 (Fig. 3A, d). PHRMT5 mono- and dimethylated histone H4R3 and PRMT5 in animals could symmetrically dimethylate histone H4R3. Therefore, to determine whether AtPRMT5 also showed the same type II methyltransferase specificity, western blotting was performed and calf thymus histone methylated by AtPRMT5 was recognized by the antibody against symmetric dimethyl histone H4R3 (Fig. 3B), as was calf thymus histone methylated by PHRMT5 (Fig. 3C). To further confirm that AtPRMT5 was a type II methyltransferase, a thin-layer chromatography (TLC) assay was performed after acidic hydrolysis of histone H4 that was methylated by AtPRMT5 in the presence of 3H-labeled S-adenosyl-l-Met (SAM). Compared with MMA and either ADMA or SDMA standards, we observed that the 3H-labeled methylated Args comigrated with both MMA and SDMA, but not ADMA (Fig. 3D). Hence, the mass spectrometry analysis, western blot, and TLC analysis support the conclusion that both AtPRMT5 and PHRMT5 mono- and symmetrically dimethylate histone H4 at R3 and that AtPRMT5 is a bona fide type II PRMT

Visit the PubMed ArticleWe tested whether the BOP proteins could stimulate transcription when tethered to DNA by assaying constructs consisting of the Gal4 DNA binding domain (BD) fused to either BOP1 (BD-BOP1) or BD-BOP2 (Figure 1A) in in vivo plant transcription assays (Huq et al., 2004). Transfection of unfused BOP1 or BOP2 did not generate luciferase activation beyond the baseline level of transcription (Figure 1B). By contrast, transfection with BD-BOP1 or BD-BOP2 activated transcription 11.2- and 8.6-fold above the baseline level, respectively (Figure 1B). Cotransfection of BD-BOP1 with BD-BOP2 produced similar fold induction values to those of BD-BOP1 or BD-BOP2 alone (Figure 1B). These results demonstrate that BOP1 and BOP2 have the capacity to activate transcription, dependent on their recruitment to the target promoter

Visit the PubMed ArticleFirst, a protein fusion of NINJA with the GAL4 DNA-binding domain (DBD) could repress the basal activity of a promoter containing upstream activation sequence (PUAS) elements in tobacco protoplasts (Fig. 3c). Second, a NINJA fragment containing the EAR motif, but lacking a JAZ interaction domain, was sufficient for repression. Conversely, deletion of the domain A or mutation of three conserved Leu residues in the EAR motif abolished the repression capacity of NINJA (mEAR, Fig. 3c). Third, the transcriptional activation of the PUAS by a DBD-MYC2 fusion protein could be counteracted by co-expression with NINJA (Fig. 3d). Together, these results establish NINJA as a transcriptional repressor of jasmonate responses

Visit the PubMed ArticleIn order to investigate directly the activity of the Arabidopsis VKORC1 domain, its fused VKORC1-Trx-like and individual VKORC1 versions were separately expressed in yeast, removing the chloroplast transit peptide. A C-terminal DAIHDEL consensus motif was added to both versions in order to mimic the retention in the endoplasmic reticulum, as naturally occurs for VKORC1 in mammalian cells (Furie and Furie, 1992). Immunoblots using the anti-Trx-like serum verified that the fused recombinant protein was indeed present in its corresponding microsomal preparation, as indicated by the 35-kDa protein band (Figure 4a). Controls with microsomes prepared from cells expressing the VKORC1 domain on its own or from cells transformed with the vector alone showed no immunosignal (Figure 4a). Nor was any signal detected when the blot was probed with the pre-immune serum (Figure 4a). The oxidoreductase activity of the VKORC1-Trx-like- and VKORC1-containing microsomes was then assayed using phylloquinone as a substrate (24 μM) and DTT as a source of electrons, and monitoring the formation of phylloquinol by HPLC fluorescence, as is classically performed in VKORC1 assays using mammalian microsomes (Chu et al., 2006; Fasco et al., 1982; Lasseur et al., 2005). Phylloquinone reductase activity was readily detected with both fused and separate VKORC1 versions (Figure 4b). In each case, the formation of quinol was proportional to the quantity of enzyme assayed, and was strictly dependent upon the presence of DTT (Figure 4b,c). The specific activities of the fused and separate VKORC1 domains were not significantly different: 1.05 ± 0.11 and 1.00 ± 0.18 nmol mg−1 protein h−1, respectively. These values are within the range of VKORC1-specific activities measured in rat liver microsomes (0.4–11.8 nmol mg−1 protein h−1) at the same substrate concentration (Fasco et al., 1982; Lasseur et al., 2005). The background formation of quinol measured in the vector-only control is attributable to non-specific oxidoreductase activities, as yeast does not contain vitamin K and lacks orthologs of VKORC1 ... To corroborate this result and to test for the substrate specificity of the Arabidopsis VKORC1 homolog, microsomal fractions were assayed using various conjugated naphthoquinone or benzoquinone species as substrates. Menaquinone-4 that only differs from phylloquinone by the degree of unsaturation of its side chain was as efficiently reduced to its quinol form than phylloquinone (Table 1). As for phylloquinone, the specific activities of the fused and separate VKORC1 domains were not statistically different (Table 1). On the other hand, unlike the mammalian VKORC1 enzyme, the fused and separate plant VKORC1 domains did not reduce phylloquinone epoxide into phylloquinone (Table 1). Nor was any activity detected with the conjugated benzoquinone species plastoquinone-9 and ubiquinone-10 (Table 1). Both VKORC1-Trx-like and its separate VKORC1 domains are thus functional, and display strict specificity for the quinone forms of naphthalenoid conjugates

Visit the PubMed ArticleOur data show that degradation of the 5′ ETS in Arabidopsis requires cooperation between the 5′→3′ and 3′→5′ exoribonucleolytic pathways. The main degradation route for the 5′ ETS upstream of the P site involves XRN2 and XRN3 (Figure 6a) (Zakrzewska-Placzek et al., 2010). A second cleavage at P′ releases the remaining part of the 5′ ETS, possibly after generation of the P–A3 fragment by cleavage in the ITS1. The excised 3′ fragment of the 5′ ETS is rapidly degraded by a 3′→5′ exoribonucleolytic pathway involving the RNA helicase AtMTR4 and RRP6L2

When resolved on a 6% acrylamide gel, the signal actually corresponds to two bands, the lower of which is absent in rrp6l2 (Figure 6c).

Córdoba-Cañero D, Roldán-Arjona T, Ariza RR - Arabidopsis ARP endonuclease functions in a branched base excision DNA repair pathway completed by LIG1
Visit the PubMed ArticleTo rule out the possibility that the BER deficiency in lig1 RNAi plants was an indirect effect of their pleiotropic phenotype, we looked for additional evidence of LIG1 function during repair. We performed DNA repair reactions with WT cell extracts in the presence of increasing amounts of anti-LIG1 antibody (Figure 6) (Waterworth et al., 2009). The results show that the anti-LIG1 serum strongly inhibits SN- and LP-BER of uracil (Figure 6, lanes 13–15 and 16–18), but does not affect either AP incision (lanes 1–3) or gap filling (lanes 4–6 and 7–9). We also confirmed that the anti-LIG1 serum inhibits ligation of a DNA substrate that mimics a nicked DNA repair intermediate (Figure 6b). Furthermore, we found that the BER capacity of extracts inhibited by anti-LIG1 was restored to near-WT levels by addition of exogenous T4 DNA ligase (Figure 6c). Altogether, these results indicate that LIG1 is required to perform the ligation step during plant BER

Lee S, Seo PJ, Lee HJ, Park CM - Accelerated cell death 2 suppresses mitochondrial oxidative bursts and modulates cell death in Arabidopsis
Visit the PubMed ArticleTo examine whether the NTL4 protein possesses transcriptional activity, the full-size NTL4 and truncated 4ΔC sequences were fused in-frame to the GAL4 DNA binding domain-coding sequence, and the fusion constructs were transformed into yeast cells (Saccharomyces cerevisiae) (Kim et al., 2006). Yeast cells expressing either the NTL4 or the 4ΔC construct grew equally well on selective medium lacking histidine and adenine, and showed elevated β-galactosidase activity (Figure 1d). We also performed a GAL4 transient expression assay using Arabidopsis protoplasts (Miura et al., 2007). The effector plasmid, the reporter plasmid containing the GUS (β-glucuronidase) reporter gene, and the plasmid containing the Renilla luciferase gene (Yoo et al., 2007), which was used to normalize the measurements, were co-transformed into Arabidopsis protoplasts (Figure 1e, left panel). The assays revealed that transient expression of the NTL4 and 4ΔC genes enhanced GUS activity approximately threefold compared to the vector control (Figure 1e, right panel), indicating that the NTL4 protein is a transcriptional activator

Both proteins are capable of catalyzing the production of acetoacetyl CoA from acetyl CoA, but, as indicated by the kcat constants for the two enzymes (503 ± 26 and 87 ± 5 min−1, respectively), AACT2 is a more efficient catalyst than AACT1 by a factor of six. The higher catalytic efficiency is primarily due to a higher Vmax value, and the Km is twofold lower for AACT2 (Figure S2

Bao C, Wang J, Zhang R, Zhang B, Zhang H, Zhou Y, Huang S - Arabidopsis VILLIN2 and VILLIN3 act redundantly in sclerenchyma development via bundling of actin filaments
Visit the PubMed ArticleAs shown in Figure 6(a), no obvious breaks along actin filaments were detected after introduction of buffer only (see also Video Clip S1). However, after perfusion of 1 nm VLN2 in the presence of 1 μm Ca2+, numerous breaks along actin filaments were detected (Figure 6b and Video Clip S2), and an increasing number of breaks were detected after the concentration of VLN2 was increased (Figure 6d, Table S1 and Video Clips S2 and S3), suggesting that VLN2 severs actin filaments in a dose-dependent manner. To determine the threshold of calcium concentration required for severing activity, 1 nm VLN2 and various concentrations of free Ca2+ were introduced into the perfusion chamber. After free [Ca2+] was elevated to 1 μm, the actin filament-severing activity of VLN2 was very prominent (Figure 6c, Table S1, and Video Clips S2, S4 and S5), implying that the actin filament-severing activity of VLN2 is biologically relevant. The severing frequency is much greater than that of VLN3 and VLN5 (Khurana et al., 2010; Zhang et al., 2010). Taken together, these results suggest that VLN2 severs actin filaments in a dose-dependent manner, and that physiological Ca2+ levels are sufficient to trigger severing activity

Visit the PubMed ArticleWe next decided to determine whether VLN2 can bundle actin filaments. The results showed that the amount of sedimented actin increased substantially in the presence of 500 nm VLN2 (Figure 5e, lane 4) compared to actin alone (Figure 5e, lane 2) under low-speed centrifugation, suggesting that VLN2 is able to form actin filament higher-order structures. Moreover, we found that the amount of sedimented actin decreased when the free calcium concentration was increased (Figure 5f). As the increase in calcium concentration did not decrease the affinity of VLN2 binding to actin filaments (Figure 5d), it may be that the elevation in the concentration of free calcium increased VLN2-mediated actin depolymerization, which probably resulted from both VLN2-mediated filament severing and barbed end capping
Bao C, Wang J, Zhang R, Zhang B, Zhang H, Zhou Y, Huang S - Arabidopsis VILLIN2 and VILLIN3 act redundantly in sclerenchyma development via bundling of actin filaments
Visit the PubMed ArticleA seeded actin elongation assay was then performed to test whether VLN2 caps the barbed end of actin filaments. VLN2 inhibited actin elongation in a dose-dependent manner (Figure S9A). A representative Kd value of 9.4 nm was calculated by fitting the data in Figure S7A to equation 1 (Figure S9B). A mean Kd value of 9.4 ± 1.4 nm was calculated from three independent experiments. We also determined whether the variation in calcium concentration affected the affinity of VLN2 for the barbed end of actin filaments, and found that the inhibitory effect of VLN2 on actin elongation increased while the free calcium concentration was elevated (Figure S9C), implying that the capping activity may be regulated by calcium

Most actin filaments behave as single filaments in the absence of villins (Figure 5g, left). However, in the presence of VLN2, actin filaments were organized into large bundles (Figure 5g, middle). VLN5 (Zhang et al., 2010) was used as a positive control

Visit the PubMed ArticleWe next addressed biochemical parameters of the CPK28 protein and investigated whether CPK28 enzyme activity is correlated with CPK28 function in shoot development. Firstly, Strep-tagged versions of full-length CPK28 protein and its D188A variant were generated. Due to this single amino acid exchange in the active centre of the enzyme, the phospho-transfer can no longer be catalysed rendering the kinase inactive. After transient expression in the heterologous Nicotiana benthamiana plant system, affinity purified and immobilised protein was subsequently subjected to in vitro kinase assays using the synthetic peptide, Syntide 2, as a substrate (Witte et al., 2010). Full-length CPK28 was active only in the presence of calcium (Figure 5a) and this calcium-dependent CPK28 kinase activity was shown to be time dependent (Figure 5b). Almost no activity could be detected in the absence of calcium or when the D188A variant of the protein kinase was assayed

Visit the PubMed ArticleSTA1 has a major role in pri-miRNA splicing. In fact, of all tested pri-miRNAs, accumulation of apparent splicing intermediates or misspliced transcripts was observed in se-1 and hyl1-2, but not in sta1-1 (Figure 5), strongly suggesting a significant role of STA1 in pri-miRNA splicing steps, rather than in the cleavage of pri-miRNAs into mature miRNAs

Visit the PubMed ArticleWe measured the expression levels of each intron that contains at least three unique probes and found that 695 introns had a significantly higher expression in sta1-1 than in Col-RD29A-LUC (Supplementary Table S1), indicating that they were not spliced properly in sta1-1. This list includes the first intron in the COR15A transcript as expected from our published result (34). Among 695 retained introns, 295 (42%) were the first intron and 104 (15%) were the second intron, indicating that similar to CBC and SE (31), STA1 has significant effect on splicing at the 5'-end of the transcripts. These results confirm our previous conclusion that STA1 functions in pre-mRNA splicing

The effector plasmid had a WRKY57 or WRKY8 gene driven by the cauliflower mosaic virus (CaMV) 35S promoter. As shown in Figure 2C, coexpression of the WRKY57 gene resulted in significantly lower GUS activity than coexpression of the WRKY8 gene. This supported the hypothesis that WRKY57 is a negative regulator of senescence-associated genes

Visit the PubMed ArticleBoth atLSG1 proteins belong to the YlqF/YawG /family of GTPases (Figure 1a). Common for such GTPases is a kcat in the range of 0.1–0.2 min−1 (Table 1). To check if atLSG1-1 and atLSG1-2 possess GTPase activity in vitro, we expressed both proteins as His14-MBP fusions in E. coli. The proteins were purified by affinity chromatography using NiNTA followed by TEV cleavage and further purification by size exclusion chromatography. The purified proteins were incubated with [α-32P]-GTP and products at different time points were analysed on TLC plates (Figure 1d). Both proteins hydrolysed [α-32P]-GTP and released [α-32P]-GDP in a time-dependent manner (Figure 1d). No hydrolysis occurred in the negative control without protein (Figure 1d). The kcat calculated from multiple turnover experiments (Jelic et al., 2003) is 0.19 ± 0.02 min−1 and 0.13 ± 0.03 min−1 for atLSG1-1 and atLSG1-2, respectively.
