Transcriptome analysis reveals the molecular mechanism of yield increases in maize under stable soil water supply.

This study explored the physiological and molecular mechanisms of yield increase in maize under stable soil water content (SW) conditions. Results of the study showed that under SW conditions, corn yield increased by 38.72 and 44.09% in 2019 and 2020, respectively. Further, it was found that dry mat...
