An Expression Alteration of Small RNA Profiling in Autotriploids Derived from Rice Twin-Seedlings

ABSTRACT: Although closely related to plant evolution, polyploid sRNAs (small RNAs) were seldom studied with experiments, especially on genome-wide range. In this study, a rice twin-seeding (two seedlings from the same grain) line SARII-658 was employed to isolate autotriploids. Those autotriploids possess unique merits to study the two interesting topics: (i) natural polyploids; (ii) the autonomy of epigenetic variations (i.e. sRNAs) from genome doubling per se. sRNA libraries were prepared from those diploid-autotriploid twin-seedlings and then were sequenced to produce 13,308,226 short sequence reads in total. Out of the 35,429 miRNA genes and siRNA clusters, 1,547 (4.36%) changed their expression levels for two folds or above after genome doubling (thereinafter, referred those sRNAs as ploidy-se
