Several cDNAs encoding animal K+ channel beta subunits have been recently cloned and sequenced. We report the molecular cloning of a rice plant homolog of these animal beta subunits. The rice cDNA (KOB1) described in this report encodes a 36 kDa polypeptide which shares 45% sequence identity with these animal K+ channel beta subunits. and 72% identity with the only other cloned plant (Arabidopsis thaliana) K+ channel beta subunit (KAB1). The KOB1 translation product was demonstrated to form a tight physical association with a plant K+ channel alpha subunit. These results are consistent with the conclusion that the KOB1 cDNA encodes a K+ channel beta subunit. Expression studies indicated that KOB1 protein is more abundant in leaves than in either reproductive structures or roots. 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. Leaf sheaths are known to accumulate excess K+ and act as reserve sources of this cation when new growth requires remobilization of K+. Leaf sheaths were found to contain higher levels of KOB1 protein than the blade portions of leaves. It was further determined that when K+ was lost from older leaves of plants grown on K+-deficient fertilizer, the loss of cellular K+ was associated with a decline in both KOB1 mRNA and protein. This finding represents the first demonstration (in either plants or animals) that changes in cellular K+ status may specifically alter expression of a gene encoding a K+ channel subunit."xsd:string |
