Transcriptional profiling of the Arabidopsis root quiescent center

Project description:The Arabidopsis quiescent center (QC) is a small group of cells with low mitotic activity located at the center of the root stem cell niche. Its transcriptional profile was previously analyzed using two repeats of cells FACS isolated using the WOX5 marker. To get more power in analyzing QC transcriptional profile, we generated three additional samples of the QC, using the QC-specific marker WOX5.

Transcription profiling of Arabidopsis pvip1 pvip2 seedlings

Project description:Early establishment of the apical-basal axis is prerequesite for correct embryonic development in Arabidopsis. The hypophysis is derived from the basal cell of the early embryo and is indispensible for root development; it gives rise to the root quiescent center and the central columella. Arabidopsis pvip1 pvip2 mutants show defects in embryonic root development and give rise to rootless seedlings. We used microarrays to study the gene regulation of rootless mutant embryos in comparison with wild type. Experiment Overall Design: Arabidopsis pvip1 pvip2 mutant and Col-0 wild type seedlings (10 days after germination) were compared using Affymetrix ATH1 arrays. Roots of wild type seedlings were removed and the vestigial hypocotyl of mutants was cut to control for wounding effects.

Genetic and molecular regulation of increased photosynthetic cell number contributes to leaf size heterosis in Arabidopsis

Project description:Heterosis is an important genetic phenomenon that has been observed and widely utilized in agriculture. However, the genetic and molecular bases of heterosis are unclear. Through transcriptome-wide association studies (TWAS) and expression quantitative trait locus (eQTL) analysis to integrate genome, transcriptome, and phenotype of a half-sibling Arabidopsis hybrid population, we report that the genetic and molecular bases of variations in leaf growth heterosis can be explained by the varied expression levels of growth-regulating genes resulting from distinct sets of heterozygous eQTLs carried by the half-sibling hybrids. In F1 relative to parent, the degree of up-regulated gene expression in the cell cycle pathway in the shoot apex and the photosynthesis pathway in the true leaf positively correlates with true leaf area heterosis level, and this is affected by the accumulation of superior heterozygous eQTLs. This was further corroborated by the major contribution of increased photosynthetic cell number to leaf area heterosis in the population.

Transcript profiling of ERF115 transgenic Arabidopsis thaliana

Project description:This experiment was set up in order to identify the (direct) transcriptional targets of the Ethylene Response Factor 115 (ERF115) transcription factor. Because ERF115 expression occurs in quiescent center (QC) cells and strong effects on the QC cells were observed in ERF115 overexpression plants, root tips were harvested for transcript profiling in order to focus on root meristem and QC specific transcriptional targets.

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 “growth signal” and thus ensure the indeterminate root growth.
