smallRNA-seq of Solanum lycopersicum bearing the sulfurea epiallele in nrpe1 versus WT. smallRNA-seq of Solanum lycopersicum bearing the sulfurea epiallele in nrpe1 versus WT

Plants bearing a sulfurea epiallele (TAB2sulf) were crossed with nrpe1 (largest polV subunit) mutants in Solanum Lycopersicum. 7 plants of a F3 progeny expected to be 100% TAB2sulf and segregating for the nrpe1 mutation were sequenced. 4 plants bear the nrpe1 mutation and 3 plants have NRPE1 WT alleles. The aim of the experiment was to compare sRNA accumulation between nrpe1 and WT F3 plants with particular interest on SlTAB2 (Solyc02g005200) which has been previously associated with paramutation in the sulfurea background. Both WT and nrpe1 F3 plants had methylation levels consistent with the TAB2sulf epiallele. nrpe1 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.
