Figure 1: Phenotypically variable msh1 mutants produce enhanced growth progeny on crossing to wild type.
From: Arabidopsis MSH1 mutation alters the epigenome and produces heritable changes in plant growth
(a) Crossing scheme for creating epi-lines. (b) The epiF4 plants show enhanced plant biomass, rosette diameter and floral stem diameter relative to Col-0. (c) Enhanced growth phenotype of the epiF4; this enhanced growth is observed in ~100% of F4 progeny deriving from a selected epiF3 line. (d) The epiF4 phenotype at maturity. (e) Scheme to derive early-generation msh1 materials for methylome analysis. (f) Segregating progeny from a single hemizygous plant. First-generation msh1 −/− plants are marked with triangles. (g) Second-generation siblings from a single first-generation msh1 −/− parent exhibited variegation and size variation.
