PhaseTank: genome-wide computational identification of phasiRNAs and their regulatory cascades

Emerging evidence has revealed phased siRNAs (phasiRNAs) as important endogenous regulators in plants. However, the integrated prediction tools for phasiRNAs are still limited. In this article, we introduce a stand-alone package PhaseTank for systematically characterizing phasiRNAs and their regulatory networks. (i) It can identify phasiRNAs/tasiRNAs functional cascades (miRNA/phasiRNA -> PHAS loci -> phasiRNA -> target) with high sensitivity and specificity. (ii) By one command analysis, it generates comprehensive annotation and quantification of the predicted PHAS genes from any given sequences. (iii) PhaseTank has no restriction with regards to prior information of sequence homology of unrestricted organism origins.
