UGTs through the genus Brassica
Contents
Introduction
The genus Brassica
The Brassica genome has undergone more polyploidy than Arabidopsis thaliana. Arabidopsis thaliana is notable for being a model organism because of its complexity paired with a relatively small genome. (I think.)
Duplication Events
The Brassica genome has undergone two tetraploidy and two hexaploidy events, one more than Arabidopsis, since the eudicot paleohexaploidy event which gave rise to Vitis, Prunus, Arabidopsis, and Brassica.
Triangle of U
The "Triangle of U" describes the genetic relationship between six species of Brassica: Brassica rapa, Brassica nigra, Brassica oleracea, Brassica juncea, Brassica carinata, and Brassica napus. B. juncea, B. carinata and B. napus are allotetraploids, hybrids with four times the chromosome set of haploids.
UGT Gene Family
UGT functions
Uridine diphosphate (UDP) glycosyltransferases (UGTs) mediate transfer of glycosyl residues from activated nucleotide sugars to acceptor molecules (Tang Unleashing the Genome of the Brassica rapa).
UGT chemistry
By mediating transfer of glycosyl residues from activated nucleotide sugars to acceptor molecules, UGTs regulate properties of those acceptors such as bioactivity, solubility and transport within cells and throughout organisms (Ross Higher plant glycosyltransferases).
