OAR@ICRISATResponses to Increased Moisture Stress and Extremes: Whole Plant Response to Drought under Climate ChangeVVadezauthorJKholovaauthorSChoudharyauthorZPaulauthorMTerrierauthorLKrishnamurthyauthorpRatna KumarauthorN CTurnerauthorIn this chapter, we tackle the physiology of plant water use from the angle of how this will be modified in a context of a changing climate. Two recent reviews cover a number of innovative aspects to drought research, in particular in relation to research on roots, and advocate the need to look at the soil–root–shoot–atmosphere water management in a comprehensive and dynamic manner (Vadez et al. 2007, 2008). In the present chapter, we revisit some of these aspects from the perspective of changing climatic conditions and explore the major issues that climate change will bring about, and how it will affect crop production and in particular under water-limited conditions. These issues can be broadly grouped into two categories: (1) thermodynamic aspects of the soil–plant–atmosphere water relations and (2) growth and development aspects.Climate Change2011WileyBook Section
