  • drought tolerance mechanisms;
  • drought tolerance phenotypes;
  • glycophytic plants;
  • regulatory mechanisms


This chapter focuses on drought tolerance mechanisms about which less is known at the molecular level. All of authors discussion in the chapter is about glycophytic plants that are unable to shut down under severe drought and instead must maintain metabolic activity as well as possible at low water potentials. They discuss some important drought tolerance phenotypes for which there is a relative lack of information on the underlying molecular mechanisms. Conversely, they also discuss some regulatory mechanisms likely to be of importance in drought tolerance but that are only beginning to be characterized in detail. They focus on some drought tolerance phenotypes where there is a great potential for molecular genetics to uncover how these processes are regulated and better understand how they contribute to overall drought tolerance. They also focus on drought tolerance traits and some relatively uncharacterized signaling mechanisms that may control them.
