Abundant, unusual RNAs on the leaf surface
Plant Science Research WeeklyIt seems that there is no end to the surprises that RNA provides. To the old-school trio of mRNA, tRNA, and rRNA, the past 20 years have added miRNA, siRNA, tasiRNA and others, all with unique and specific roles in regulating gene activity. More recently, evidence has been accumulating that demonstrates…
Plant cells secrete diverse RNA species, including small RNAs, long noncoding RNAs and circular RNAs
