Relationship between Peanut Aspergillus flavus Resistance and Glycogen Synthase Kinase-3

doi:10.7668/hbnxb.2011.05.001

Abstract

Abstract: It has been reported that Glycogen synthase kinase-3 was upregulated in peanut developing seed coat of Aspergillus flavus sensitive line.In this paper,we analyszed the expression differences of GSK3β gene in developing seeds between Aspergillus flavus resistant lines and susceptible lines with bioinformatic methods and QPCRmethods.The results indicated in early fruits stage,GSK3β gene was upregulated in Aspergillus flavus resistant lines.GSK3β is negative regulator for brassinosteroids,which inhibits cell elongation.Thus it′s possible that GSK3β is a inhibitative factor in sizes of seeds and fruits in peanut development,direct or indirect related to the resistance to Aspergillus flavus.

Key words: Peanut, Glycogen synthase kinase-3, Bioinformatics, Aspergillus flavus resistance, Fruit development
