• 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, 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
