Genome-wide identification and expression analysis of PUB genes in cotton.

ABSTRACT:

Background

The U-box gene encodes a ubiquitin ligase that contain U-box domain. The plant U-box gene (PUB) plays an important role in the response to stresses, but few reports about PUBs in cotton were available. Therefore research on PUBs is of great importance and a necessity when studying the mechanisms of stress- tolerance in cotton.

Results

In this study, we identified 93, 96, 185 and 208 PUBs from four sequenced cotton species G. raimondii (D₅), G. arboreum (A₂), G. hirsutum (AD₁) and G. barbadense (AD2), respectively. Prediction analysis of subcellular localization showed that the PUBs in cotton were widely localized in cells, but primarily in the nucleus. The PUBs in cotton were classified into six subfamilies (A-F) on the basis of ph
