Genome-wide identification and characterization of DUF789 genes in cotton: implications for fibre development.

ABSTRACT:

Background

Proteins containing domains of unknown function (DUFs) play a crucial role in plant growth, development and stress adaptation, but many of them are still uncharacterized. The DUF789 family is one of the least studied of these, especially in economically significant crops like cotton (Gossypium spp.), whose possible function in fibre production and abiotic stress response is yet unknown.

Results

In a comprehensive genome-wide analysis, a total of 91 DUF789 genes were identified in four Gossypium species: G. arboreum, G. barbadense, G. raimondii and G. hirsutum. Evolutionary and phylogenetic analyses placed the GhDUF789 proteins into different clades, with purifying selection identified as the major evolutionary force.
