Genome-wide analysis of PHABULOSA targets in Arabidopsis root meristem

Project description:We report the discovery of a root growth program in Arabidopsis that is independent of a functional quiescent center (QC). In this regulatory program, PHABULOSA (PHB), posttranscriptionally regulated by SHR and SCR, plays a central role. In phb shr and phb scr mutants, root meristem/growth activity recovers significantly. Interestingly, this recovery does not accompany the resurgence of QC cells. PHB regulates apical root growth in stele cells of the root meristem, located proximal to the QC. Our genome-wide investigation suggests that PHB exerts its influence on root growth by regulating auxin-cytokinin homeostasis. Apical root growth was restored when cytokinin levels were genetically reduced in the shr mutant. Conversely, when miRNA-resistant PHB was expressed in the root stele cells, apical root growth and meristem functions were significantly inhibited without blocking the QC identity. Taken together, our investigation reveals two mechanisms through which SHR regulates root growth and stem cell activities: one is to specify and maintain the QC and the other is to regulate the proximal meristem activity through PHB and cytokinin. In this regulation, QC seems to be more involved in maintaining the M-bM-^@M-^\growth signalM-bM-^@M-^] and thus ensure the indeterminate root growth. Total 7 samples (2 replicates of shr-2 mutant (high PHABULOSA expression) vs. 2 replicates of shr-2 phb-6 (low/absent PHABULOSA expression). 3 replicates of Wild type used as reference sample.

Genome-wide transcriptome analysis bZIP29 dominant negative repressor line in root tips of Arabidopsis

Project description:The Arabidopsis basic leucine zipper transcription factor bZIP29 of the bZIP group I TF family, expressed mainly in proliferative tissues, is functionally characterized in this study. In roots, bZIP29 is highly expressed in the quiescent centre and the columella cells of the root apical meristem. Mutant analyses demonstrate that bZIP29 regulates root meristem cell number and root gravitropic responses. RNA-seq transcriptome profiling of the root meristem shows that bZIP29 target genes are linked to cell wall organization, and that gene regulatory networks controlling proper root meristem organization are intensively rewired upon its perturbation.

Brassica rapa subsp. chinensis Transcriptome

Project description:Deep RNA-Seq of two Brassica rapa genotypes—R500 (var. trilocularis, Yellow Sarson) and IMB211 (a rapid cycling variety)—using eight different tissues (root, internode, leaf, petiole, apical meristem, floral meristem, silique, and seedling) grown across three different environments (growth chamber, greenhouse and field) and under two different treatments (simulated sun and simulated shade) generated 2.3 billion high-quality Illumina reads.
