Publication
- OsMYB511 encodes a MYB domain transcription activator early regulated by abiotic stress in rice., 2015, Genet Mol Res.

Genbank accession number
Key message
- In the present research, a full-length MYB gene OsMYB511 was identified from rice seedlings through microarray data
- Tissue-specific expression analysis indicated that OsMYB511 was highly expressed in rice panicles at earlier development stage
- Induction of OsMYB511 by cold stress was dramatic in japonica cultivar Jiucaiqing as compared to indica IR26
- OsMYB511 encodes a MYB domain transcription activator early regulated by abiotic stress in rice.
- The subcellular localization and yeast hybrid assay suggested that OsMYB511 is nucleus-localized transcription activator
- Compared with wild-type (WT) plants, transgenic plants over-expressing OsMYBR1 exhibited much greater tolerance to drought stress and decreased sensitivity to abscisic acid (ABA)
- Our results provide evidence that OsMYBR1 is involved in mediating plant responses to ABA and drought
