Project description:Enriched BR-body samples (JS299) samples and negative control samples (JS221) from a strain lacking BR-bodies. BR-body enrichment was performed by differential centrifugation as in 10.1016/j.xpro.2020.100205. Each sample was collected in three biological replicates.

Project description:BR-body mutant strains were globally profiled for mRNA half-lives using rifampicin treatment followed by RNA-seq. JS38 (wild type) was compared to JS221 (lacking the intrinsically disordered CTD and unable to form BR-bodies), JS233 (unable to recruit degradosome components into BR-bodies), and JS299 (active site mutant of RNase E).

Project description:Divergence has occured between the B10.BR-H2k H2-T18a/SgSnJJrep and B10.BR-H2k H2-T18a/SgSnJ (drifted) mouse strains, resulting in altered antigenic recognition and differential bone marrow engraftment capability. The microarray data demonstrate that the transcriptional profile of genes associated with hematopoiesis differs between lineage negative (as a marker for hematopoietic stem cells) bone marrow cells isolated from the B10.BR-H2k H2-T18a/SgSnJJrep and B10.BR-H2k H2-T18a/SgSnJ (drifted) mouse strains.

Project description:Brassinosteroids (BRs) are growth-promoting steroid hormones in plants. BRs affect plant growth by regulating panels of downstream genes. Much effort has been made to establish BR-regulated gene expression networks, but these published expression networks poorly overlap. To address this, here we build an optimal BR-regulated gene expression network. 7- and 24-day-old seedlings of constitutive photomorphogenesis and dwarfism (cpd) mutant and bri1-701 (brassinosteroid-insensitive 1) brl1 (BRI1-like receptor genes 1) brl3 (BRI1-like receptor genes 3) triple mutant seedlings were treated with brassinolide (BL), and RNA sequencing (RNA-seq) was used to detect differentially expressed genes (DEGs). By this approach, we generated a transcriptomic database of 4498 DEGs and identified 110 transcription factors specifically respond to BR at different stage. Moreover, we found that among the identified BR-responsive transcription factors, ABSCISIC ACID-INSENSlTIVE4 (ABI4), an ethylene response factor (ERF) transcription factor, inhibits BR-regulated growth. Compared to wild-type plants, the abi4-102 mutant was less sensitive to brassinazole (BRZ) and more sensitive to BR. Next, we performed a chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) assay and found that ABI4 directly binds to the BAK1 (BRI1 Associated receptor Kinase 1) promoter and inhibits transcription. These results provide new insights into BR-responsive gene functions in regulating plant growth at different stages and may serve as a basis for predicting gene function, selecting candidate genes, and improving the understanding of BR regulatory pathways.

Project description:Although a wide range of interactions between BRs and auxin have been recognized, knowledge about the direct molecular mechanism of interaction between them in specific physiological processes is very limited. In this study we found that auxin resisitent mutant msg2/iaa19 and arf7 were also resisitant to the BR effect on morphogenensis of dark-grown Arabidosis seedlings. Moreover, BR signaling transcription factor BZR1 can directly bind to promoter regions of IAA19 and ARF7. Microarray analysis revealed that a number of gene transcripts showed reduced BR response in msg2 and the control mutant axr2, suggesting the crucial role of IAA19 in mediating BR effects. Taken together, our results suggested that BRs regulate morphogenesis of dark-grown seedling by employing auxin signaling components IAA19 and ARF7.

Project description:MicroRNAs and phytophormes are all small molecular signals that play important roles in regulating development and environmental responses in plants. The interplay between them allow the plants to better converge multiple inner and outer signals to optimizing their survival strategy. So far, the knowledge of how miRNAs are involved in brassinosteroid (BR) signaling is lacking. Here, we report the finding of miR394 and its target gene LEAF CURLING RESPONSENESS (LCR), which were transcriptionally responsive to BR, participate in BR signaling in regulating hypocotyls elongation in Arabidopsis. By phenotypic analyzing of a set of transgenic and mutants, miR394 was found to act as a negative regulator in BR signaling in hypocotyls elongation, while its target gene on the contrary. Genetically, miR394 functions upstream of BIN2 and BZR1/BES1, but partially downstream or independent with BRI1 and BSU1. RNA-seq analysis further supports that miR394 inhibits BR signaling through BIN2 because miR394 co-regulate significant number of genes together with BIN2. Additionally, miR394 improved the accumulation of BIN2 but decreased the protein amount of BZR1 and BES1, which can be phosphorylated by BIN2. miR394 also repressed the transcription of PRE1/5/6 and EXP8, the key hypocotyls elongation regulating genes, which had been reported to be BZR1/BES1 targets. These findings revealed a new pathway that miRNA involved in BR signaling in Arabidopsis.
