Metabolic bypass of the tricarboxylic acid cycle during lipid mobilization in germinating oilseeds. Regulation Of nad+-dependent isocitrate dehydrogenase versus fumarase

abstract：:This report examines the effect of anaerobic stress on the expression of sucrose synthase in maize (Zea mays L.). Following 24 hours of anaerobic treatment, alcohol dehydrogenase displayed the classical characteristics of induction: increased mRNA and protein levels. However, there was no detectable increase in sucros...
