Abstract
Glycosylation mediated by Family-1 UDP-glycosyltransferases (UGTs) plays crucial roles in plant growth and adaptation to various stress conditions. Prunus mume is an ideal crop for analyzing flowering for its early spring flowering characteristics. Revealing the genomic and transcriptomic portfolio of the UGT family in P. mume, a species in which UGTs have not yet been investigated, is therefore important. In this study, 130 putative UGT genes were identified and phylogenetically clustered into 14 groups. These PmUGTs were distributed unevenly across eight chromosomes and 32 tandem duplication and 8 segmental duplication pairs were revealed. A highly conserved intron insertion event was revealed on the basis of intron/exon patterns within PmUGTs. According to RNA-seq data, these PmUGTs were specifically expressed in different tissues and during the bud dormancy process. In addition, we confirmed the differential expression of some representative genes in response to abscisic acid treatment. Our results will provide important information on the UGT family in P. mume that should aid further characterization of their biological roles in response to environmental stress.
Highlights
Increasing evidence is suggesting that glycosylation mediated by glycosyltransferases (GTs) plays crucial roles in plant growth and response to biotic and abiotic stresses [1]
Increasing studies indicate that UGT proteins play important roles in plant growth and adaptation to environmental stress
To identify the candidate UGT genes in P. mume, a total of 120 Arabidopsis UGT protein sequences were retrieved from CAZy and 168 peach UGT proteins were downloaded from Phytozome V12.1
Summary
Increasing evidence is suggesting that glycosylation mediated by glycosyltransferases (GTs) plays crucial roles in plant growth and response to biotic and abiotic stresses [1]. 105 GT families have been identified in the carbohydrate-active enzyme database (CAZy, available online: http://www.cazy.org/) the largest of which is family 1 (GT1) [5,6]. Because it uses UDP-glucose as the sugar donor molecule, GT1 is known as UDP-glycosyltransferase (UGT) [1]. Putative UGT genes have recently been identified in many plants, including 107 in Arabidopsis, 148 in Glycine max and 148 in Zea mays [4,9,10,11]. The number of isolated putative UGT genes includes 168 in Prunus persica, 254 in Malus domestica and 184 in Vitis vinifera [12,13]
