Modifying expression of closely related UDP-glycosyltransferases from pea and Arabidopsis results in altered root development and function
doi: 10.1111/j.1399-3054.2007.00900.x Glycosyltransferases (GTs) play diverse roles in cellular metabolism by modifying the activities of structural and regulatory metabolites. Previous studies indicated that a Pisum sativum UDP-glycosyltransferase (PsUGT1) is essential for plant development, and suggested a role for this enzyme in the regulation of the cell division cycle. Here we report that ...
متن کاملMeristem-localized inducible expression of a UDP-glycosyltransferase gene is essential for growth and development in pea and alfalfa.
PsUGT1, which encodes a microsomal UDP-glucuronosyltransferase, was cloned from root tips of Pisum sativum. PsUGT1 expression is correlated with mitosis and strongly induced in dividing cells. A region at the C terminus of the encoded protein is closely related to the UDP-glucuronic acid binding site consensus sequence, and the protein encoded by PsUGT1 catalyzes conjugation of UDP-glucuronic a...

expansins are cell wall proteins that due to changes in ph, causing the expansion of the cell wall .these proteins are causing deformation of walls through loosening hydrogen bonds between the cellulose and polymer matrix microfibrils .in this study, a root specific gene called atexpa18 -that directly affect the formation of root hairs and also its role have been proved in other parts of the p...
متن کاملPiscine UDP-glucuronosyltransferase 1B.
Glucuronidation is an important detoxification pathway for organic pollutants in fish. We report here the isolation and characterisation of UDP-glucuronosyltransferases (UGT) genes from the closely related marine flatfish, plaice (Pleuronectes platessa) and flounder (Platichthys flesus). The deduced amino acid sequences share greater similarity with mammalian UGT1 family genes than UGT2 genes (...
متن کاملCharacterization of Arabidopsis AtUGT85A and AtGUS gene families and their expression in rapidly dividing tissues.
In humans, uridine 5'-diphosphate glucuronosyltransferase (UGT) operates in opposition to glucuronidase (GUS) to control activity of diverse metabolites such as hormones by reversible conjugation with glucuronic acid. Previous data revealed that, as in mammals, these enzymes are required for plant life in that a UGT from Pisum sativum (PsUGT1) controls plant development by opposing endogenous G...
