Abstract
The response of two root associated bacteria Pseudomonas pseudoalcaligenes and Bacillus pumilus were studied in the saltsensitive rice GJ17 cultivar to salinity under controlled environmental growth conditions for protection of plant from adverse effect of salinity Salinity affects the growth of saltsensitive cultivar but inoculation of plant growth promoting rhizobacteria PGPR reduces the harmful effect of salinity The present study states that PGPR helps to reduce lipid peroxidation and superoxide dismutase activity in saltsensitive GJ17 cultivar under salinity and play an important role in the growth regulation for positive adaptation of plants to salt stress This study shows that inoculation of paddy Oryza sativa with such bacteria could provide salttolerant ability by reducing the toxicity of reactive oxygen species by reducing plant cell membrane index cell caspaselike protease activity and programmed cell death and hence resulted in increase cell viability As these isolates remain associated with the roots the effects of tolerance against salinity are observed here Results also indicate that isolated PGPR strain help in alleviating up to 15 salinity stress as well as improve tolerance
