smallRNA-seq of Solanum lycopersicum segregating for the sulfurea epiallele in cmt3 versus WT. smallRNA-seq of Solanum lycopersicum segregating for the sulfurea epiallele in cmt3 versus WT

Plants bearing a sulfurea epiallele (TAB2sulf) were crossed with cmt3 mutants in Solanum Lycopersicum. 6 plants of a F2 progeny segregating both for TAB2sulf and cmt3 mutation were sequenced. 4 plants bear the cmt3 mutation and 2 plants have CMT3 WT alleles. the aim of the experiment was to compare sRNA accumulation between cmt3 and WT plants with particular interest on SlTAB2 (Solyc02g005200) which has been previously associated with paramutation in the sulfurea background. The WT plants had methylation levels consistent with the TAB2sulf epiallele and the cmt3 plants had methylation levels consistent with TAB2+ (low DNA methylation). cmt3 and sulfurea parental controls are added in single replicates and a WT cv M82 plant is also sequenced as control. More replicates of WT and M82 are sequenced in a related experiment.
