Plasticity of wheat seedling responses to K⁺ deficiency highlighted by integrated phenotyping of roots and root hairs over the whole root system.

ABSTRACT: The availability in the soil of potassium (K⁺), a poorly mobile macronutrient required in large quantities for plant growth, is generally suboptimal for crop production in the absence of fertilization, making improvement of the ability of crops to adapt to K⁺ deficiency stress a major issue. Increasing the uptake capacity of the root system is among the main strategies to achieve this goal. Here, we report an integrative approach to examine the effect of K⁺ deficiency on the development of young plant entire root system, including root hairs which are known to provide a significant contribution to the uptake of poorly mobile nutrients such as K⁺, in two genetically distant wheat varieties. A rhizobox-type methodology was developed to obtain highl
