Glycosyltransferase gene family 1, also known as uridine diphosphate glycosyltransferase (UGT), is the largest glycosyltransferase family in plants, playing a vital role in their growth and development. In this study, 244
UGT
genes with conserved PSPG motifs were identified in the genome of
Quercus robur
L. The collinearity analysis results showed that tandem repeat was the main way of
UGT
genes expansion in
Q. robur
, with 21 groups of 55 tandem repeat genes.
UGT
genes were divided into 15 subgroups A–P; group K was lost, and the gene structure and conserved domain of the same subgroup were basically the same. Cis-element analysis showed that upstream 2,000 bp promoter sequence of
UGT
genes contained light response elements, plant hormone response elements, and stress-related cis-elements, which indicated that
UGT
genes of
Q. robur
might be regulated by various metabolic pathways. In particular, some
UGT
s in group L of
Q. robur
contained a conserved promoter structure. The expression pattern analysis results demonstrated that
UGT
genes of groups B, D, E, and I were differentially expressed under
Tortrix viridana
L. stress. The expression of
UGT
s in group E decreased under stress, the expression of group L increased, and that of genes in groups D and B were different. The functions of
UGT
genes in E and L groups are relatively conservative, and their functions may also conserve among species. The study results have a particular reference value for further research on the function of
Q. robur UGT
genes.
