Project description:Arabidopsis msh1 mutants display developmental reprogramming (dr) phenotypes, include reduction in growth, enhanced branching, and delayed maturation and flowering time. MSH1-epi lines were derived by crossing MSH-dr lines with Col-0 wild type, followed by selection for homozygous MSH1/MSH1 F2 plants and serial self-pollination. MSH1-epiF3 plants displayed phenotypic variation in plant growth, showing enhanced growth, larger rosette diameter, thicker floral stems and earlier flowering time. We carried bisulfite sequencing and uncover the methylome changes accompany the heritable MSH1-epi phenotypes that condition dramatic variation in plant growth. 3 samples examined: wild type, Msh1-epiF3, msh1 mutant
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.
