^a P, N, and L stand for PA64s, 93-11, and LYP9, respectively. Numbers 1, 2, and 3 denote libraries made from materials of panicles at the pollen-maturing stage, leaves at the milking stage, and roots at the first tillering stage, respectively. ^b Mapped tags refer to those that mapped to the virtual transcripts based on predicted genes that are (a) supported by transcripts that have authentic 3'-UTR sequences and (b) lacking supporting evidence but defined by adding an artificial 3'-UTRs).
