HKT1和HAK1等转运子介导钾离子的高亲和吸收以及K+/Na+共运转,从而可能增强Na+替代K+的能力;KAT1和KST1等离子通道介导钾离子的累积和转运,从而调节气孔细胞的渗透压,控制气孔运动.阐述了植物生物膜上离子转运机制和钾营养高效机理的某种可能的关系.这些转运子和通道的高效表达可能与植物钾营养高效有很大的相关性.

HKT1 and HAK1 transporters mediates high-affinity K+ uptake and K+/Na+ co-transport, which can enhance the substitution of Na+ for K+. KAT1 and KST1 channels mediate K+ accumulation, which can regulate the osmotic pressure in stomotal cells and control the movement of stomata. We present a putative relationship between the membrane transport systems and potassium use efficiency in plants. The quantity and quality of expression of the above transporter or channels may greatly correlate with potassium use efficiency in plants.
