Gene Details:

• MSU gene ID: LOC_Os02g57240
• RAPdb gene ID: Os02g0817500
• Gene Symbol: KOB1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
