Genome-wide characterization of the UDP-glycosyltransferase gene family in upland cotton.

ABSTRACT: Uridine diphosphate (UDP)-glycosyltransferases (UGTs) involved in many metabolic processes are ubiquitous in plants, animals, microorganisms and other organisms and are essential for their growth and development. Upland cotton contains a large number of UGT genes. In this study, we aimed to identify UGT family members in the genome of upland cotton (Gossypium hirsutum L.) and analyze their expression patterns. Bioinformatics methods were used to identify UGT genes from the whole genome of upland cotton (Gossypium hirsutum L. acc. TM-1). Phylogenetic analysis was conducted based on alignment of UGT proteins from upland cotton, and the gene structure, motif and chromosome localization were analyzed for the H subgroup of the UGT family. And the physical and chemical properties and expressions of the genes in the H subgroup of this family were also analyzed. A total of 274 UGT genes were identified from the whole genome of upland cotton and were divided into nine subgroups based on phylogenetic analyses. In subgroup H, 36 genes were distributed on 18 chromosomes. The subfamily genes were simple in the structure, 19 of its members contained two introns, and the others contained only one intron. The qRT-PCR results and transcriptomic data indicated that most of the genes had a wide range of tissue expression characteristics. And the phylogenetic analysis results and expression profiles of these genes revealed tissues and different UGT genes from this crop. Taking RNA-seq, RT-qPCR, and quantitative trait locus (QTL) mapping together, our results suggested that GhUGT6 and GhUGT105 in subgroup H of the GhUGT gene family could be potential candidate genes for cotton yield, and GhUGT16, GhUGT103 might play a vital role in fiber development.

Project description:BackgroundGlycosyltransferases comprise a highly divergent and polyphyletic multigene family that is involved in widespread modification of plant secondary metabolites in a process called glycosylation. According to conserved domains identified in their amino acid sequences, these glycosyltransferases can be classified into a single UDP-glycosyltransferase (UGT) 1 superfamily.ResultsWe performed genome-wide comparative analysis of UGT genes to trace evolutionary history in algae, bryophytes, pteridophytes, and angiosperms; then, we further investigated the expansion mechanisms and function characterization of UGT gene families in Brassica rapa and Brassica oleracea. Using Hidden Markov Model search, we identified 3, 21, 140, 200, 115, 147, and 147 UGTs in Chlamydomonas reinhardtii, Physcomitrella patens, Selaginella moellendorffii, Oryza sativa, Arabidopsis thaliana, B. rapa, and B. oleracea, respectively. Phylogenetic analysis revealed that UGT80 gene family is an ancient gene family, which is shared by all plants and UGT74 gene family is shared by ferns and angiosperms, but the remaining UGT gene families were shared by angiosperms. In dicot lineage, UGTs among three species were classified into three subgroups containing 3, 6, and 12 UGT gene families. Analysis of chromosomal distribution indicates that 98.6 and 71.4% of UGTs were located on B. rapa and B. oleracea pseudo-molecules, respectively. Expansion mechanism analyses uncovered that whole genome duplication event exerted larger influence than tandem duplication on expansion of UGT gene families in B. rapa, and B. oleracea. Analysis of selection forces of UGT orthologous gene pairs in B. rapa, and B. oleracea compared to A. thaliana suggested that orthologous genes in B. rapa, and B. oleracea have undergone negative selection, but there were no significant differences between A. thaliana -B. rapa and A. thaliana -B. oleracea lineages. Our comparisons of expression profiling illustrated that UGTs in B. rapa performed more discrete expression patterns than these in B. oleracea indicating stronger function divergence. Combing with phylogeny and expression analysis, the UGTs in B. rapa and B. oleracea experienced parallel evolution after they diverged from a common ancestor.ConclusionWe first traced the evolutionary history of UGT gene families in plants and revealed its evolutionary and functional characterization of UGTs in B. rapa, and B. oleracea. This study provides novel insights into the evolutionary history and functional divergence of important traits or phenotype-related gene families in plants.
