Rice variation induced by the introduction of exogenous DNA has become an important method of improving rice varieties and creating new germplasms. In this study, we transferred maize genomic DNA fragments to the receptor of Nipponbare rice using a modified “pollen-tube pathway” method. Material from mutant rice B1 and B2 were acquired and 14 specific bands were obtained from the material using amplified fragment length polymorphism analysis. From the 14 specific sequences obtained, there were 3791 bp, including 144 base mutations with a base mutation rate of 3.80%.

OsMYB511 encodes a MYB domain transcription activator early regulated by abiotic stress in rice

P. Huang, Chen, H., Mu, R., Yuan, X., Zhang, H. S., and Huang, J., OsMYB511 encodes a MYB domain transcription activator early regulated by abiotic stress in rice, vol. 14, pp. 9506-9517, 2015.

The MYB-domain proteins exist universally across diverse organisms and regulate numerous processes during the plant life cycle. In the present research, a full-length MYB gene OsMYB511 was identified from rice seedlings through microarray data. Induction of OsMYB511 by cold stress was dramatic in japonica cultivar Jiucaiqing as compared to indica IR26.
