• Key message
  • The OsMYB2-overexpressing plants accumulated greater amounts of soluble sugars and proline than wild-type plants under salt stress
  • Overexpression of OsMYB2 enhanced up-regulation of genes encoding proline synthase and transporters
  • This study isolated a rice R2R3-type MYB gene, OsMYB2, and functionally characterized its role in tolerance to abiotic stress by generating transgenic rice plants with overexpressing and RNA interference OsMYB2
  • No difference in growth and development between the OsMYB2-overexpressing and wild-type plants was observed under normal growth conditions, but the OsMYB2-overexpressing plants were more tolerant to salt, cold, and dehydration stresses and more sensitive to abscisic acid than wild-type plants
  • These findings suggest that OsMYB2 encodes a stress-responsive MYB transcription factor that plays a regulatory role in tolerance of rice to salt, cold, and dehydration stress
  • Expression of OsMYB2 was up-regulated by salt, cold, and dehydration stress
  • A R2R3-type MYB gene, OsMYB2, is involved in salt, cold, and dehydration tolerance in rice
• Connection
  • Osmyb2, Osmyb5, Cloning and expression of five myb-related genes from rice seed, RT-PCR analysis showed that Osmyb2, Osmyb3 and Osmyb5 genes were expressed in all tissues examined
  • Osmyb2, Osmyb3~SG3~SMG3, Cloning and expression of five myb-related genes from rice seed, RT-PCR analysis showed that Osmyb2, Osmyb3 and Osmyb5 genes were expressed in all tissues examined
  • OsDREB2A, Osmyb2, A R2R3-type MYB gene, OsMYB2, is involved in salt, cold, and dehydration tolerance in rice, There was greater up-regulation of stress-related genes, including OsLEA3, OsRab16A, and OsDREB2A, in the OsMYB2-overexpressing plants
  • OsLEA3~OsLEA3-1, Osmyb2, A R2R3-type MYB gene, OsMYB2, is involved in salt, cold, and dehydration tolerance in rice, There was greater up-regulation of stress-related genes, including OsLEA3, OsRab16A, and OsDREB2A, in the OsMYB2-overexpressing plants
  • Osmyb2, OsWRKY5, Inactivating transcription factor OsWRKY5 enhances drought tolerance through abscisic acid signaling pathways., Transcriptome deep sequencing and RT-qPCR analyses demonstrated that the expression of abiotic stress-related genes including rice MYB2 (OsMYB2) was upregulated in oswrky5 knockout mutants and downregulated in oswrky5-D mutants
  • Osmyb2, OsWRKY5, Inactivating transcription factor OsWRKY5 enhances drought tolerance through abscisic acid signaling pathways., Moreover, dual-luciferase, yeast one-hybrid, and chromatin immunoprecipitation assays showed that OsWRKY5 directly binds to the W-box sequences in the promoter region of OsMYB2 and represses OsMYB2 expression, thus downregulating genes downstream of OsMYB2 in the ABA signaling pathways
  • OsbZIP14, Osmyb2, Integrated ATAC-Seq and RNA-Seq Data Analysis to Reveal OsbZIP14 Function in Rice in Response to Heat Stress., This study identified three TF genes, including OsbZIP14, OsMYB2, and OsHSF7, by integrating transcriptomic and epigenetic sequencing data analysis of rice in response to heat stress
