As Jatropha is targeted to be grown in marginal land where soil
nutrient is low, the requirement for soil fertilizer will be higher
than other crops. Today, worldwide, there is also a profound need
to explore varied agroecological niches for the presence of native
beneficial microorganisms. Thus, a better understanding of the
presence of the plant growth promoting endophytic actinobacteria
in Jatropha is important. From our study, we may speculate that
habitat adapted symbiotic ACC deaminase-producing PGPE actinobacteria
from Jatropha plant could be beneficial to its ecological
fitness. This interaction could be very helpful for enhancement of
Jatropha plant growth and development in abiotic stress soil
environment.
