Abstract

Soils abiotic stress is the biggest individual stress that limits the productivity of crops and distribution of plant species worldwide. Salt and drought soils affects the development of the radical system and thereby the entire plants organisms. Many aspects on how roots grow, develop and respond to changes in soil conditions are poorly understood. To achieve adaptation to soil environment of root growth, plants can adjust their root growth rate and direction determining the architecture of the radical system and the exploration of the medium. Almost all of this growth happens in the first millimeters of the root apex. What happens in this relatively small mass of cells can impact the performance of the crops under not optimal conditions like the hydric and salt stress. Many of the phenomena implicated in root cells response to external stimulus are regulated by membrane transport activity and their regulation factors. This review focuses in what we have learnt about the adaptation of plants to drought and salinity: how the roots sense and continues his growth in soils under abiotic stress.
