ABSTRACT: 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 msh1 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. Arabidopsis Col-0 wild type and epiF3 plant tissues were collected for RNA extration and hybridization on Affymetrix.

Project description:The Arabidopsis msh1 mutant show various growth phenotype. We use microarray analysis to characterize gene expression pattern for two of the phenotypes - variegation and stunted growth. Wild type and msh1 RNAi variegated and stunted tissues were collected for RNA extration and hybridization on Affymetrix.
Project description:The soybean msh1 RNAi transgenic line show various growth phenotype. We use microarray analysis to characterize gene expression pattern for two of the phenotypes - variegation and stunted growth. Wild type and Arabidopsis msh1 mutant albino tissues were collected for RNA extration and hybridization on Affymetrix.

Project description:To generate msh1 memory revertant population, msh1 memory plant was used to pollinate Col-0 to generate F1 population. Derived F1 progenies were self-pollinated to generate F2 populations. F2 plants were self-pollinated to produce F3 families that were segregationg for the msh1 memory phenotype (small dwarf plants with delayed flowering).
Project description:Col-0 plants were transformed with MSH1 RNAi construct. Transgene positive plant was self pollinated and transgene was segregated in subsequent generation, and screened for presence of transgene using PCR assay. Of transgene null plants, 20% plants displayed delayed in flowering, smaller in size, and lighter green termed as memory phenotype.
Project description:To generate epi-lines, two third-generation msh1 T-DNA mutant (SAIL_877_F01) plants were used to pollinate Col-0 to generate two independent F1 populations. Derived F1 progenies were self-pollinated to generate F2 populations that were genotyped for the msh1 T-DNA mutation. MSH1 F2 plants were self-pollinated to produce F3 families that were used in the study.
