OsHMGB1 functions as a transcriptional repressor of OsNRT2.2 in rice: Calcium-regulation and additive function with OsCCA1.
OsHMGB1 is identified as a key repressor of OsNRT2.2, associated with OsCBL1-dependent nitrate signaling and act additively with OsCCA1 to enhance LN tolerance, suggesting that OsHMGB1 expression levels correlate with NUE-related traits under LN conditions.
