Induction of dormancy during seed development by endogenous abscisic acid: studies on abscisic acid deficient genotypes of Arabidopsis thaliana (L.) Heynh.

abstract：MAIN CONCLUSION:Dysfunctional mutation of OsNDPK4 resulted in severe defects in root development of rice. However, the resistance of Osndpk4 against bacterial blight was significantly enhanced. Nucleoside diphosphate kinases (NDPKs) are an evolutionarily conserved family of important enzymes balancing the energy curren...
