MSH1-induced heritable enhanced growth vigor through grafting is associated with the RdDM pathway in plants.

Project description:Plants transmit signals long distances, as evidenced in grafting experiments that create distinct rootstock-scion junctions. Noncoding small RNA is a signaling molecule that is graft transmissible, participating in RNA-directed DNA methylation; but the meiotic transmissibility of graft-mediated epigenetic changes remains unclear. Here, we exploit the MSH1 system in Arabidopsis and tomato to introduce rootstock epigenetic variation to grafting experiments. Introducing mutations dcl2, dcl3 and dcl4 to the msh1 rootstock disrupts siRNA production and reveals RdDM targets of methylation repatterning. Progeny from grafting experiments show enhanced growth vigor relative to controls. This heritable enhancement-through-grafting phenotype is RdDM-dependent, involving 1380 differentially methylated genes, many within auxin-related gene pathways. Growth vigor is associated with robust root growth of msh1 graft progeny, a phenotype associated with auxin transport based on inhibitor assays. Large-scale field experiments show msh1 grafting effects on tomato plant performance, heritable over five generations, demonstrating the agricultural potential of epigenetic variation.

RNA sequencing of progenies of Col-0 grafted on msh1; Col-0 grafted on dcl2,3,4,msh1 quadruple mutant in Arabidopsis [msh1_graft_root_RNA-seq]

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.

Small RNA sequencing of progenies of Col-0 grafted on msh1; Col-0 grafted on dcl2,3,4,msh1; msh1 mutant; dcl2,3,4,msh1 quadruple mutant in Arabidopsis [msh1_graft_sRNA-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). 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.

MSH1 disruption in plants triggers RdDM-mediated reprogramming of phenotypic plasticity (RNA-Seq)

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.

MSH1 disruption in plants triggers RdDM-mediated reprogramming of phenotypic plasticity (Bisulfite-Seq II)

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).
