Exploiting the functionality of root systems for dry, saline, and nutrient deficient environments in a changing climate.

Abstract

The authors highlight a few research topics related to abiotic stresses - mostly drought stress, but also nutrient limitation (especially phosphorus) and salt stress - where roots and their hydraulics are at the center stage. First, they provide an update on root structure, root hydraulics, and modes of water and nutrient absorption, mainly focusing on how inter- and intra-specific variations in these aspects can modify the way roots respond to a range of abiotic stresses. They then review scattered reports across a range of crops showing the contribution of roots to stress tolerance, and then report their own assessment of the role of roots using near isogenic lines (NILs)
