Raffinose and its precursor galactinol accumulate in plant leaves during abiotic stress. RAFFINOSE SYNTHASE (RAFS) catalyzes raffinose formation by transferring a galactosyl group of galactinol to sucrose. However, whether RAFS contributes to plant drought tolerance and, if so, by what mechanism
Maize (Zea mays) GALACTINOL SYNTHASE (GolS) is a key enzyme in the raffinose biosynthetic pathway. We have previously characterized the maize GolS2 (ZmGolS2) gene as heat shock induced in maize germinating seeds and cultured cells. Here we report the identification, isolation and characterization of
To investigate the natural variability of leaf metabolism and enzymatic activity in a maize inbred population, statistical and network analyses were employed on metabolite and enzyme profiles. The test of coefficient of variation showed that sugars and amino acids displayed opposite trends in their
GALACTINOL SYNTHASE is the first committed enzyme in the raffinose biosynthetic pathway. We have previously characterized the maize (Zea mays) GALACTINOL SYNTHASE2 gene (ZmGOLS2) as abiotic stress induced. To further investigate the regulation of ZmGOLS2 gene expression, individual luciferase
Pathogenic fungi drastically affect plant health and cause significant losses in crop yield and quality. In spite of their impact, little is known about the carbon sources used by these fungi in planta and about the fungal transporters importing sugars from the plant-fungus interface. Here, we
Plant cell walls play a fundamental role in several ways, providing structural support for cells, resistance against pathogens and facilitating the communication between cells. The glycosyltransferase family 8 (GT8) is involved in the formation of the plant cell wall. However, the evolutionary
