Abstract
Salinity stress affect plant growth and development by causing osmotic stress, and nutrient imbalances through excess Na+, K+ and Cl- ion accumulations that induce toxic effects during germination, seedling development, vegetative growth, flowering, and fruit set. However, the effects of salt stress on such processes, especially in polyploidised leguminous plants remains unexplored and scantly reported compared to their diploid counterparts. This paper discusses the physiological and molecular response of legumes towards salinity stress based osmotic and ionic imbalances in plant cells. A multigenic response involving various compatible solutes, osmolytes, ROS, polyamines and antioxidant activity, together with genes encoding proteins involved in the signal transduction, regulation and response mechanisms to this stress were identified and discussed. This discussion reaffirms polyploidisation as the driving force in plant evolution and adaptation to environmental stress constraints such as drought, feverish temperatures, and in particular, salt stress. As a result, thorough physiological and molecular elucidation of the role of gene duplication through induced autopolyploidisation and possible mechanisms regulating salinity stress tolerance in grain legumes must be further studied.
