Transcriptome analysis of genes regulated by overexpression of LATERAL ORGAN BOUNDARIES (LOB) in Arabidopsis thaliana

ABSTRACT: The Arabidopsis thaliana transcription factor LATERAL ORGAN BOUNDARIES (LOB) is expressed in the boundary between the shoot apical meristem and initiating lateral organs. To identify genes regulated by LOB activity, we used an inducible 35S:LOB-GR line. This analysis identified genes that are differentially expressed in response to ectopic LOB activity.

Project description:The Arabidopsis thaliana transcription factor LATERAL ORGAN BOUNDARIES (LOB) is expressed in the boundary between the shoot apical meristem and initiating lateral organs. To identify genes regulated by LOB activity, we used an inducible 35S:LOB-GR line. This analysis identified genes that are differentially expressed in response to ectopic LOB activity. 35S:LOB-GR and Col wild-type seedlings were treated with dexamethasone (DEX) or mock-treated. Three biological replicates were conducted for each treatment.

Transcriptome analysis of genes regulated by CUP-SHAPED COTYLEDON1 (CUC1) transcription factor in Arabidopsis thaliana

Project description:Samples 1 & 2: Comparison of gene expression between wild type (ecotype Ler) and 35S:CUC1, in which CUP-SHAPED COTYLEDON1, a master regulator of the shoot meristem and boundary establishment, is constitutively expressed under the cauliflower mosaic virus 35S promoter. Samples 3 & 4: Comparison of gene expression between stm-1 (ecotype Ler) and stm-1 35S:CUC1 RNA was isolated from cotyledons of 5-day-old (for Ler vs 35S:CUC1) or 10-day-old (for stm vs 35S:CUC1stm) seedlings. Two independent biological replicates were analyzed for each comparison.

Gene expression in leaf blades of the rice Os-LBD37 overexpressor line RK16331-13

Project description:The 5th and 6th leaf blades of the rice Os-LBD37 overexpressor line RK16331-13 and the empty vector control line FOX3 were examined. LBD37 belongs to the plant- specific LOB- (Lateral Organ Boundary) domain family proteins first characterized in Arabidopsis. Results point towards an involvement of the rice LBD37 (OsLBD37) ortholog of Arabidopsis in nitrogen metabolism- and senescence- related processes.

Transcriptomic analysis of REVOLUTA and mir165a cell-types of Arabidopsis shoot apical meristem

Project description:Dorso-ventral (DV) patterning at the Shoot Apical meristem (SAM) is essential for organogenesis in Arabidopsis. Dorsal and ventral gene expressed domains are separated by boundaries from where the new organ initiation starts. Here by using cell-types specific transcriptomics approach, we have identified dorsal, ventral and boundary specific genes in SAM.

CPL4 is a suppressor of de novo shoot organogenesis from roots of Arabidopsis thaliana

Project description:De novo shoot organogenesis (DNSO) is a commonly used pathway for plant biotechnology, and is a hormonally regulated process, where auxin and cytokinin coordinates suites of genes encoding transcription factors, general transcription factors, and RNA metabolism machinery genes. Here we report that silencing Arabidopsis thaliana CTD phosphatase-like 4 (CPL4RNAi), which increases phosphorylation level of RNA polymerase II (pol II) CTD, altered lateral root development and DNSO efficiency of the host plants, suggesting an importance of precise control of pol II activities during DNSO. Under standard condition, roots of CPL4RNAi lines produced no or few lateral roots. When induced by high concentration of auxin, CPL4RNAi lines failed to produce focused auxin maxima at the meristem of lateral root primordia, and produced fasciated lateral roots. By contrast, root explants of CPL4RNAi lines were highly competent for DNSO. Efficient DNSO of CPL4RNAi lines were observed even under 10 times less cytokinin required for wild type explants. Transcriptome analysis showed CPL4RNAi but not wild type explants expressed high levels of shoot meristem related genes during priming by high auxin/cytokinin ratio, and subsequent shoot induction with cytokinin. These results indicate that CPL4 functions as a repressor of the early stage of DNSO, during acquisition of competency by high auxin/cytokinin ratio, perhaps via regulation of pol II activities.
