• Information
  • Symbol: OsDIS1
  • MSU: LOC_Os03g24040
  • RAPdb: Os03g0356414
• Publication
  • The SINA E3 ligase OsDIS1 negatively regulates drought response in rice, 2011, Plant Physiol.
  • OsDIS1-mediated stress response pathway in rice, 2011, Plant Signal Behav.
• Genbank accession number
  • AK058336
• Key message
  • Here we also show that OsDIS1 interacts with OsSKIPa, a drought and salt stress positive regulator in rice
  • Overexpression of OsDIS1 reduced drought tolerance in transgenic rice plants, while RNA interference silencing of OsDIS1 enhanced drought tolerance
  • We recently showed that OsDIS1 (Oryza sativa drought-induced SINA protein 1), a SINA type E3 ligase, is involved in the drought-stress signal transduction in rice
  • OsDIS1 plays a negative role in drought stress tolerance through the transcriptional regulation of diverse stress-related genes and also possibly through the posttranslational regulation of its interacting protein OsNek6 in rice
  • Here, we report that OsDIS1 (for Oryza sativa drought-induced SINA protein 1), a C3HC4 RING finger E3 ligase, is involved in drought-stress signal transduction in rice (O
  • The expression of OsDIS1 was up-regulated by drought treatment
  • Microarray analysis revealed that a large number of drought-responsive genes were induced or suppressed in the OsDIS1 overexpression plants under normal and drought conditions
  • Together, these results demonstrate that OsDIS1 plays a negative role in drought stress tolerance through transcriptional regulation of diverse stress-related genes and possibly through posttranslational regulation of OsNek6 in rice
  • The SINA E3 ligase OsDIS1 negatively regulates drought response in rice
• Connection
  • OsDIS1, OsSKIPa, OsDIS1-mediated stress response pathway in rice, Here we also show that OsDIS1 interacts with OsSKIPa, a drought and salt stress positive regulator in rice
  • OsDIS1, OsPUB67, A U-box E3 ubiquitin ligase OsPUB67 is positively involved in drought tolerance in rice., OsPUB67, a U-box E3 ubiquitin ligase, may interact with two drought tolerance negative regulators (OsRZFP34 and OsDIS1) and improve drought tolerance by enhancing the reactive oxygen scavenging ability and stomatal closure
  • OsDIS1, OsPUB67, A U-box E3 ubiquitin ligase OsPUB67 is positively involved in drought tolerance in rice., Further evidence showed that several E3 ubiquitin ligases interacted with OsPUB67, especially OsRZFP34 and OsDIS1, which are negative regulators of drought tolerance
