Review on Role of Proline on Coffee Under Drought Conditions

Abstract

Drought is one of the major constraints that limiting production of crop worldwide. Plants tolerate drought by many ways like morphological, physiological and biochemical tolerance mechanisms. Plants develop mechanisms to tolerant abiotic stress by osmotic adjustment that is usually accomplished by uptake of inorganic ions, as well as the accumulation of proline. Proline is a universal osmo-protectant and acts as an osmolyte and antioxidant, and it is one of the most important compatible solutes that play a vital role in osmotic adjustment in crops under drought stress. Accumulation of proline considered as adaptive mechanisms in drought-tolerant coffee genotypes. In general, more attention on biochemical traits for drought tolerant mechanisms on coffee should be given. Therefore, looking for high proline accumulation genotype under drought conditions is important for further coffee breeding program to release drought tolerant genotypes.
