Arabidopsis lyrata flowering tissues small RNAs

ABSTRACT: Small RNA sequences from Arabidopsis lyrata flowering tissues, as isolated from flowering tissues of two biological replicates. These data were analyzed to 1) discover new micoRNAs in A. lyrata 2) examine microRNA processing accuary in A. lyrata and 3) to examine patterns of 24nt siRNA accumulation in A. lyrata. Two small RNA libraries from flowering tissues of two biological replicates were analyzed using an Applied Biosystems SOLiD™ System

Twenty-one-nucleotide microRNAs (miRNAs) and 24-nucleotide Pol IV-dependent small interfering RNAs (p4-siRNAs) are the most abundant types of small RNAs in angiosperms. Some miRNAs are well conserved among different plant lineages, whereas others are less conserved, and it is not clear whether less-conserved miRNAs have the same functionality as the well conserved ones. p4-siRNAs are broadly produced in the Arabidopsis genome, sometimes from active hot spot loci, but it is unknown whether indivi  ...[more]
