MicroRNAs (miRNAs) are 20 to 24 nucleotides short RNAs involved in posttranscriptional regulation in plants and animals. MiRNAs are processed from larger precursors with extensive secondary structure. In plants, a total of 286 miRNA genes in Arabidopsis, rice and maize had been identified by March 2005, clustered in 43 families. Here, we report the bioinformatic identification of 200 members of the 43 miRNA families in the genomes of maize, sorghum, medick and poplar. Furthermore, we report… CONTINUE READING
