Gene Details:

• MSU gene ID: LOC_Os01g03720
• RAPdb gene ID: Os01g0128000
• Gene Symbol: MYB1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• MYB1 was transcriptionally induced in leaf sheaths and old leaf blades.
• Furthermore, MYB1 affected the elongation of the primary root in a Pi-dependent manner and lateral roots in a Pi-independent manner.
• Moreover, gibberellic acid (GA)-triggered lateral root elongation was largely suppressed in wild-type plants under Pi starvation conditions, whereas this suppression was partially rescued in MYB1 mutant lines, correlating with the up-regulation of a GA biosynthetic gene upon MYB1 mutation.
• Taken together, the findings of this study highlight the role of MYB1 as a regulator involved in both Pi starvation signaling and GA biosynthesis.
• Mutation of MYB1 led to an increase in Pi uptake and accumulation, accompanied by altered expression of a subset of Pi transporters and several genes involved in Pi starvation signaling.
