  Endobiotics moderate ROS formation in plant cells during drought stress.

Global food security strongly depends on high-nutrient crops such as pulses.  However, long and severe drought affects negatively crop growth and yield due to an increased level of reactive oxygen species or ROS (H2O2, âOH) formed in plants exposed to stress. ROS levels can increase dramatically thus resulting in significant damage to cell structures.  In this study, we assessed the effects of fungal endobiotics on pulses in terms of balancing the formation of ROS with their elimination by scavenging system. The overproduction of ROS resulted in oxidative cell damage in control plants, whereas plant cells colonized by endophytes showed down-regulated expression of ROS. Pea (Pisum sativum) and chickpea (Cicer arietinum) germinants were assessed in terms of ROS level, formation of antioxidant enzymes, and expression of antioxidant genes under drought conditions. The knowledge from this study will help to improve crop production under drought stress conditions.
