The study on metabolic changes and regulation mechanism of Aspergillus flavus spores during germnation

the transcriptomic results showed that the differential genes at different germination stages had significant characteristics. In the early stage of germination, the spores entered an active state from a dormant state, with enhanced respiration, intensified energy metabolism, and began to synthesize amino acids, lipid and other substances. This stage had the largest number of differential genes; in the middle stage of germination, spores began to divide, and the main differential genes are nutrient trasport-related genes; in the late stage, the differential genes were also mainly nutrient transport-related genes, and the expression of secondary metabolism-related genes continued to be up-regulated.
