Gene Details:

• MSU gene ID: LOC_Os02g44310
• RAPdb gene ID: Os02g0662000
• Gene Symbol: RCc3
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Overexpression of RCc3 improves root system architecture and enhances salt tolerance in rice.
• In this study, we investigated the biological role of the rice root-specific gene RCc3 in improving root growth and responses to abiotic stress by overexpressing RCc3 in rice plants.
• RCc3 overexpression produced pleiotropic phenotypes of improved root system architecture, including increased growth of primary root, adventitious roots and lateral roots at the seedling stage.
• Further study indicated that auxin accumulation in the root was increased through auxin local biosynthesis and polar auxin transport in RCc3 overexpression lines.
• Under osmotic and heat stress conditions, the root and shoot growth were less severely inhibited in RCc3 overexpressing transgenic plants than that in wild-type plants, and the transcript levels of abiotic stress-related genes were significantly increased.
• Taken together, the data showed that RCc3 overexpression can improve rice root system, promote plant growth, and enhance plant tolerance to salt stress.
• Moreover, overexpression of RCc3 remarkably enhanced the tolerance to salt stress, with the elevated activities of antioxidant enzymes.
• RCc3 was induced by osmotic and heat stress.
