Conteúdo: | Plants in nature encounter a combination of environmental conditions that may include stresses such as drought or heat shock. The response of plants to a combination the stress abiotc induction of a large number of defense genes, and changes in genes involved in sugar metabolism. Galactinol synthase (GolS) is a key enzyme in the raffinose and stachyose biosynthetic pathway (RFOs family). This protein functions a galactosyl transferase, which catalyses the key regulatory reaction utilizing UDP-galactose and myo-inositol as substrates to form galactinol and UDP. GolS genes have often been identified as stress responsive genes in many plant species. To study the function of different isoforms of GolS during heat stress in Coffea arabica, this work was carried out with the objective to characterize the expression of three Galactinol synthase isoforms: CaGolS1, CaGolS2 and CaGolS3.
