Background:

Glycosyltransferases (GTs) play crucial roles in synthesizing plant cell-wall polysaccharides.
These enzymes are also vital for N-linked glycan addition to glycoproteins.
GTs attach sugar moieties to small molecules like hormones and flavonoids.

Purpose of the Study:

To highlight recent advancements in the identification and cloning of glycosyltransferase genes.
To report on the discovery of numerous putative glycosyltransferase genes within the Arabidopsis genome.

Main Methods:

Gene identification and cloning.
Bioinformatic analysis of the Arabidopsis genome sequence.

Main Results:

Significant progress in identifying and cloning genes encoding glycosyltransferases.
The Arabidopsis genome contains several hundred additional genes for putative glycosyltransferases.

Conclusions:

The glycosyltransferase gene family in plants is extensive.
Further research into these genes will advance our understanding of plant biochemistry and development.
