• Information
  • Symbol: PI3K
  • MSU: LOC_Os05g08810
  • RAPdb: Os05g0180600
• Publication
  • Phosphatidylinositol 3-kinase plays a vital role in regulation of rice seed vigor via altering NADPH oxidase activity, 2012, PLoS One.
• Genbank accession number
  • AK111613
• Key message
  • Phosphatidylinositol 3-kinase (PI3K) has been reported to be important in normal plant growth and stress responses
  • In this study, it was verified that PI3K played a vital role in rice seed germination through regulating NADPH oxidase activity
  • Suppression of PI3K activity by inhibitors wortmannin or LY294002 could abate the reactive oxygen species (ROS) formation, which resulted in disturbance to the seed germination
  • Taken together, these data favored the novel conclusion that PI3K regulated NADPH oxidase activity through modulating the recruitment of Rac-1 to plasma membrane and accelerated the process of rice seed germination
• Connection
  • Osrboh9~OsRBOHH, PI3K, Phosphatidylinositol 3-kinase plays a vital role in regulation of rice seed vigor via altering NADPH oxidase activity, Pharmacological experiment and RT-PCR demonstrated that PI3K promoted the expression of Os rboh9
