The plant glycosyltransferase clone collection for functional genomics

Area of Science:

• Plant biochemistry
• Enzymology
• Molecular biology

Background:

• Glycosyltransferases (GTs) are crucial enzymes in plant glycan and glycoside biosynthesis.
• Plants possess large GT families (e.g., >450 in Arabidopsis, >600 in rice) classified into over 40 families.
• Despite their importance in cell-wall and secondary metabolite synthesis, few GTs are functionally characterized.

Purpose of the Study:

• To create a comprehensive plant GT clone resource for functional genomic studies.
• To facilitate the research community's ability to investigate GT functions in plants.

Main Methods:

• Cloning of 403 (88%) CAZy-defined Arabidopsis GTs and 96 (15%) rice GTs.
• Generation of Gateway®-compatible, full-length coding sequence clones without termination codons.
• Construction of particle bombardment plasmids (pBullet) with endomembrane markers to demonstrate clone utility.

Main Results:

• A significant resource of cloned plant GTs was established, including updates to Arabidopsis GT gene models.
• The pBullet plasmids enabled localization of Arabidopsis GT14 family members to the Golgi apparatus and endoplasmic reticulum (ER).

Conclusions:

• The JBEI GT Collection provides a valuable resource for plant functional genomics.
• The developed plasmids and clones facilitate GT functional characterization and subcellular localization studies in plants.
