SPA regulation of light induced gene expressions in dark-grown Arabidopsis thaliana

ABSTRACT: The total mRNA and polysomal RNA expression profiles of wild type (Col-0) and the quadruple spa mutant (spaQ) were analyzed under dark or in 4 hour light treated condition. The gene expression changed in spaQ mutant was analyzed and compared with Col-0.

Bisulfite (methylome) sequencing of progenies of Col-0 grafted on msh1; Col-0 grafted on dcl2,3,4,msh1; Col-0 grafted on Col-0; msh1 mutant; dcl2,3,4,msh1 quadruple mutant in Arabidopsis [msh1_graft_BS-seq]

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.

Arabidopsis dark-induced senescence: wild type (Col-0) vs. pif quadruple (pif1pif3pif4pif5) mutant

Project description:Transcriptional profiling of Arabidopsis dark-induced senescence comparing wild type (Col-0) with pif quadruple (pif1/3/4/5) mutant. After synchronized germination, the plants were grown under continuous white light for 7 days and transferred to darkness for 2 days to induce senescence. Goal was to determine the effect of PIFs on transcriptomic regulation during dark-induced senescence.

Genomic evidence reveals SPA-regulated developmental and metabolic pathways in dark-grown Arabidopsis seedlings

Project description:Background: Photomorphogenesis is repressed in the dark mainly by an E3 ubiquitin ligase complex comprising CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) and four homologous proteins called SUPPRESSOR OF PHYA-105 (SPA1-SPA4) in Arabidopsis. This complex induces the ubiquitination and subsequent degradation of positively acting transcription factors (e.g., HY5, HFR1, PAP1 and others) in the dark to repress photomorphogenesis. Genomic evidence showed a large number of genes regulated by COP1 in the dark, of which many are direct targets of HY5. However, the genomic bases for the constitutive photomorphogenic phenotypes of spaQ remain unknown. Results: Here, we show that >7200 genes are differentially expressed in the spaQ background compared to wild type in the dark. Comparison of the RNAseq data between cop1 and spaQ revealed a large overlapping set of genes regulated by the COP1-SPA complex. In addition, many of the genes coordinately regulated by the COP1-SPA complex are also regulated by HY5 directly and indirectly. Moreover, a large number of genes (~2790) are predominantly regulated by SPA proteins and not by COP1, suggesting that SPA proteins might regulate many biological processes independently of COP1. Conclusions: Taken together, our data reveal that SPA proteins repress photomorphogenesis by controlling expression of a large number of genes in concert with COP1, likely through regulating the abundance of downstream transcription factors in light signaling pathways. Moreover, SPA proteins may function both in a COP1-dependent and –independent manner in regulating many biological processes and developmental pathways in Arabidopsis.
