Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the bisulfite sequencing (methylome). Tissue from the msh1 mutant and dcl2,3,4,msh1 quadruple mutants used as rootstocks was similarly collected at the bolting stage and used for the bisulfite sequencing.
Project description:Transcriptional profiling of the vegetative part of Arabidopsis comparing wild type with the shr scl23 scr triple mutant. The latter is produced by crossing the strong null alleles of shr (shr-2), scl23 (scl23-1) and scr (scr-5). The goal was to determine the effects of the GRAS transcription factors SHR, SCL23 and SCR on growth and development of the Arabidopsis shoot system by global transcriptome analysis. Two-condition experiment: Col-0 vs. shr scl23 scr triple mutant. Biological replicates: 2 WT vs. triple mutant replicates, 2 WT vs. triple mutant replicates dye-swap replicates.

Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the total RNA sequencing.
Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1) and on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on 0.5M MS growth medium and root tissue was collected after 12 days and used for the RNA sequencing.
Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the small RNA sequencing. Tissue from the msh1 mutant and dcl2,3,4,msh1 quadruple mutants used as rootstocks was similarly collected at the bolting stage and used for the small RNA sequencing.

Project description:The Jasmonate pathway regulators MYC2, MYC3 and MYC4 are central nodes in plant signaling networks integrating environmental and developmental signals to fine-tune jasmonate defenses and plant growth. Hence, their activity needs to be tightly regulated in order to optimize plant fitness. Among the increasing number of mechanisms regulating MYCs activity, protein stability is arising as a major player. However, how the levels of MYCs proteins are modulated is still poorly understood. Here, we report that MYC2, MYC3 and MYC4 are targets of BPM proteins, which act as substrate adaptors of CUL3-based E3 ubiquitin ligases. Reduction-of-function of CUL3BPM in amiR-bpm lines, bpm235 triple mutants and cul3ab double mutants enhances MYC2 and MYC3 stability and accumulation, and potentiates plant responses to JA such as root-growth inhibition, and MYC-regulated gene expression. BPM3 protein is stabilized by JA, suggesting a new negative feed-back regulatory mechanism to control MYCs activity. Our results uncover a new layer for JA-pathway regulation by CUL3BPM–mediated degradation of MYC TFs.
