Scientists Work on New Rice Drought-Proofing Method

October 3, 2012

Scientists from the International Rice Research Institute (IRRI) have conducted a study that attempts to link root proteases to drought-tolerance mechanisms in rice. Proteases can reportedly act on proteins, peptides, and microbes that could be nitrogen sources for plants to help them cope with nutrient imbalances under drought condition.

The study illustrated the important mechanism of proteases for plant's nutrient uptake especially under drought conditions. It further concluded that root proteases can positively affect nutrient and water status more than any other class of proteins under drought, where some metabolic processes in plant's source tissues start suffering even before critically low levels of water are reached.
