Recent advancement of molecular understanding for combating salinity stress in maize.

This chapter reviews recent progress in the fundamental understanding of maize salt tolerance and the advancement of molecular breeding for salt-tolerant maize. Great progress has been made towards the molecular understanding of maize salt tolerance in recent years. Nevertheless, the breeding of commercial salt-tolerant maize hybrids remains challenging. Some issues that may facilitate maize molecular breeding for combating salinity stress are enumerated.
