mRNA-seq data of cotton fiber at 5DPA and 10DPA

A total of 421 Upland cotton (Gossypium hirsutum) core germplasm resources were cultivated in the field in Anyang, Henan, China. Cotton boll were tagged on the day of flowering as 0 DPA (day post anthesis) samples. Three replicates were set up for each accession, fibers at 5 DPA from at least 5 cotton bolls of different plants were collected and bulked together. Fibers at 10 DPA takes the same approach to collect. A total of 38 semi-wild cotton resources were cultivated in the field in Sanya, Hainan, China. Fibers at 10 DPA were collected by the same method. RNA extraction was performed on these fiber samples followed by sequencing.
