|a The role of DELLAs in response to light intensity under salt stress is largely unknown. Therefore, the effect of three light intensities-low (35), medium (60), and high (155) μmol m-2 s-1 on Arabidopsis plants growth under saline condition (150 mM NaCl) was evaluated. High light intensity exhibited significant growth in the number of lateral roots related to the low light. Immunoblot assay revealed increased DELLA accumulation at the seedling stage under high light intensity. High light promotes seed germination by 24-44%, whilst, lateral roots by 25-90% in wild-type ecotypes. The lateral roots increased significantly in gai (gibberellic acid insensitive mutant) as compared with gai-t6 (wild type like gibberellic acid insensitive mutant) in response to low to medium and high to medium light intensity. High light increased seedling survival rate by 67% in Col-0 (Columbia) and 60% in Ler (Landsberg erecta) and showed a 28% increase in survival rate in gai mutant under salt stress as compared to gai-t6. Furthermore, salt-stress responsive genes' expression in gai-mutant establishes the relationship of DELLA proteins with salt resistance. Together, light is a cardinal element, its optimum quantity is highly beneficial and promotes salt stress resistance through DELLA protein at seedling stage in plants
