leaves to that of total leaves) of
rice under drought

discussion
Plants are sessile and have evolved an array of distinct mechanisms to respond and adapt to abiotic stresses. Increasingly frequent occurrences of drought are the major challenges for rice production (Zhang 2007). We showed here that decreased or elevated expression of OsDIL in rice reduced or enhanced, respectively, the tolerance to drought at the vegetative and reproductive stages.
summary
In summary, OsDIL is a positive regulator for improving drought tolerance. OsDIL might transfer lipid molecules to synthesize cuticle in leaves to reduce water loss under drought and to facilitate sufficient pollen exine synthesis for microspores against drought. OsDIL could improve the plant cellular environment and promote ROS elimination to protect tapetal cells and other tissues.
