Abstract: 
Abiotic stress is a major environmental factor adversely affects cotton growth and yield. But upland cotton still has widely geographic range from most tropical to subtropical regions of the world. In this study, we sought to identify genes involved in diverse stresses including cold, drought, salinity and heat by transcriptome sequencing analysis. Our results showed that there were thousands of transcripts induced or depressed by cold, drought, heat and salinity. Of these, only less 7% transcription factors (TFs) were included which are much less than the functional genes. In addition, the D-subgenome had more genes highly expressed and being selected but less being silence and lost. These indicate the D-subgenome may contribute greater to abiotic stress tolerance of upland cotton and TFs may play critical roles to adapt to various environments.
