Molecular characterization of superoxide dismutase (SOD) genes for optimizing nitrogen-use efficiency and enhancing crop resilience against drought stress in rice.
Rehman OU, Uzair M, Alafari HA, Hu X, Farooq MS
Summary
PubMedResearchers studied genes that help rice plants manage stress from drought and low nitrogen, finding that superoxide dismutase (SOD) enzymes play a key role in protecting rice crops and improving how efficiently they use nitrogen fertilizer—potentially reducing input costs and improving yields under harsh conditions.

Key Findings
SOD genes were molecularly characterized in rice, revealing their role in neutralizing harmful reactive oxygen species during drought stress
SOD activity is linked to improved nitrogen-use efficiency (NUE), meaning plants can grow better with less fertilizer input
Overexpression or targeted regulation of specific SOD genes enhanced rice resilience under drought conditions

Species Mentioned
Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
