摘要： Small RNAs have emerged as critical regulators in the expression and function of eukaryotic genomes at the post-transcriptional level. To elucidate the functions of microRNA (miRNAs) and endogenous small-interfering RNAs (siRNAs) in tomato fruit ripening process, the deep sequencing and bioinformatics methods were combined to parse the small RNAs landscape in three fruit-ripening stages (mature green, breaker and red-ripe) on a whole genome. Two species-specific miRNAs and two members of TAS3 family were identified, 590 putative phased small RNAs and 125 cis-natural antisense (nat-siRNAs) were also found in our results which enriched the tomato small RNAs repository and all of them showed differential expression patterns during fruit ripening. A large amount of the targets of the small RNAs were predicted to be involved in fruit ripening and ethylene pathway. Furthermore, the promoters of the conserved and novel miRNAs were found to contain the conserved motifs of TATA-box and CT microsatellites which were also found in Arabidopsis and rice, and several species-specific motifs were found in parallel.
