Interspecific hybridization in tomatoes influences endogenous viral srnas and alters gene expression

HIGHLIGHTS

SUMMARY

The hypothesis that sRNAs influence gene_expression in hybrids is based on findings that they are associated with transposable_elements and that they can act either in cis or trans through their ability to base-pair with sequence motifs in a target gene or RNA. As an alternative approach, the authors crossed the same Solanum species and analyzed the selfed F4 progeny for changes to the gene_expression and sRNA relative to the parents. The findings reported here are that gene_expression and sRNA changes in independent lineages were non-random: changes to gene_expression and sRNA were more . . .
