• Information
  • Symbol: KOB1
  • MSU: LOC_Os02g57240
  • RAPdb: Os02g0817500
• Publication
  • Ectopic expression of the K+ channel beta subunits from Puccinellia tenuiflora KPutB1 and rice KOB1 alters K+ homeostasis of yeast and Arabidopsis, 2011, Mol Biotechnol.
  • Molecular cloning and expression characterization of a rice K+ channel beta subunit, 1998, Plant Mol Biol.
• Genbank accession number
  • U46758
• Key message
  • Leaf sheaths were found to contain higher levels of KOB1 protein than the blade portions of leaves
  • Yeast co-expressing PutAKT1 and the beta subunits (KPutB1 and KOB1) had better growth and higher K+-uptake ability than yeast expressing PutAKT1 alone
  • In contrast, yeast co-expressing the beta subunits (KPutB1 and KOB1) with OsAKT1 had slower growth and lower K+ uptake than yeast expressing OsAKT1 alone
  • Later-developing leaves on a rice plant were found to contain increasing levels of the protein with the flag leaf having the highest titer of KOB1
  • Expression studies indicated that KOB1 protein is more abundant in leaves than in either reproductive structures or roots
  • Ectopic expression of the K+ channel beta subunits from Puccinellia tenuiflora (KPutB1) and rice (KOB1) alters K+ homeostasis of yeast and Arabidopsis
