Overexpression of OsMYB305 in Rice Enhances the Nitrogen Uptake Under Low-Nitrogen Condition.

Excessive nitrogen fertilizer application causes severe environmental degradation and drives up agricultural production costs. Thus, improving crop nitrogen use efficiency (NUE) is essential for the development of sustainable agriculture. Here, we characterized the roles of the MYB transcription factor in nitrogen uptake and assimilation in rice.

Contributes to Arsenate Uptake and Transport in Rice.

Arsenic (As) is toxic to organisms, and elevated As accumulation in rice () grain may pose a significant health risk to humans. The predominant form of As in soil under aerobic conditions is As(V), which has a chemical structure similar to that of PO. Rice roots take up As(V) by phosphate (Pi) transporters, such as OsPT1 and OsPT8.
