Regulation of inflorescence architecture by inter-tissue-layer ligand-receptor communication between endodermis and phloem

ABSTRACT: Inflorescence architecture of Arabidopsis thaliana is regulated by ER-EPFL4/6 signaling module. To analyze the genes governed by this module, the transcriptional profiles of er-2 (allelic to er-106) mutant and epfl4 epfl6 double mutant were investigeted.

Regulation of inflorescence architecture by inter-tissue-layer ligand-receptor communication between endodermis and phloem

Project description:Inflorescence architecture of Arabidopsis thaliana is regulated by ER-EPFL4/6 signaling module. To analyze the genes governed by this module, the transcriptional profiles of er-2 (allelic to er-106) mutant and epfl4 epfl6 double mutant were investigated. 9 samples are included in this study. Three biological replicates of 33 d post germination inflorescence tips of er-2 (allelic to er-106, Lease et al., 2001) and epfl4 epfl6 were compared with wild type (Col-0) sample for changes in gene expression.

Brassinosteroids modulate meristem fate and differentiation of unique inflorescence morphology in Setaria viridis

Project description:RNA-seq was performed to profile the transcriptomes of inflorescence primordia hand-dissected from the bristleless1-1 (bsl1-1)mutant in Setaria viridis compared to wild-type controls sampled under the same conditions. Bsl1 encodes a rate limiting enzyme in BR biosynthesis, which is the ortholog of D11 from rice. Mutants are characterized by a homeotic conversion of sterile bristles to spikelets in the inflorescence.

Comparison of infloresence transcriptome of bp er vs. bp er fil

Project description:BP and ER encode proteins that act synergistically to regulate Arabidopsis inflorescence architecture. To search for genes/proteins that influence the BP/ER signaling pathways, we conducted mutagenesis of the bp er double mutant and found that a mutation in FILAMENTOUS FLOWER (FIL) suppresses many of the morphological/developmental defects in bp er. Given that FIL encodes a Zn-finger containing transcription factor, microarray analysis was conducted on bp er vs. the bp er fil line to identify genes that are misregulated and which might implicate specific genes/proteins/pathways that are involved in regulating inflorescence development.

miR396-OsGRF6 module controls rice inflorescence architecture

Project description:Developing strategies to increase rice productivity to meet global demand is one of the main challenges for breeders around the world. Here, we report a novel microRNA mediated process that increases rice grain yield in field trials. Expression of target mimicry of microRNA396 (MIM396) significantly increases rice yield by modulating the development of the auxiliary branches and spikelets through promoting the expression of Growth Regulation Factor 6 (OsGRF6). OsGRF6 coordinately induces the expression of several key factors involved in branch and spikelet development, auxin (IAA) biosynthesis, and auxin signaling pathway. Our results demonstrate that the miR396b-GRF6 module acts as a key player in shaping the inflorescence architecture of rice, which could be engineered to generate high-yield rice. This dataset records the profile of the binding peaks of OsGRF6 with GFP antibody in 35S:GRF6-GFP overexpression lines and the differential expressed genes between MIM396 and WT plants. Examination of OsGRF6 regulated genes.
