Studies to improve seed germination.

Maize is a valuable raw material for feed and food production. Healthy seed germination is important for improving the yield and quality of maize. Seed aging occurs relatively fast in crops and it is a process that delays germination as well as reducing its rate and even causing total loss of seed viability. However, the physiological and transcriptional mechanisms that regulate maize seeds especially aged seeds germination remain unclear. Coronatine (COR) which is a phytotoxin produced by Pseudomonas syringae and a new type of plant growth regulator can effectively regulate plant growth and development, regulate seed germination.
