Identification and characterization of mRNAs and lncRNAs in G. hirsutum fibers. A Representative images of individual seeds with attached fibers from 0 DPA to 35 DPA. Cotton fibers undergo three major sequential and overlapping developmental stages before maturity, including initiation, elongation and secondary cell wall biosynthesis. Transition-1 and -2 are two fiber developmental transition stages, which are from initiation to elongation and from elongation to secondary cell wall biosynthesis, respectively. The scale bars in all panels are 0.5 cm. B The pipeline of mRNAs and lncRNAs identification. C Length density distributions of lincRNAs, lncNATs and mRNAs. D Exon number per transcript of lincRNAs, lncNATs and mRNAs. E FPKM distributions of lincRNAs, lncNATs and mRNAs
