Optimal distribution of NO3-in plant tissues is an important prerequisite for improving NO3-metabolism and increasing nitrogen use efficiency(NUE).In order to test the hypothesis that long transport of NO3-from root to shoot tissues is regulated by NO3-in the protoplast outside of the vacuoles,we used Brassica napus cultivars that demonstrated either high-(Xiangyou15) or low-(814) nitrogen use efficiency(NUE)and Arabidopsis thaliana plants raised under a hydroponics system.Plants were subjected to inhibitors of selected proton pumps and 1-aminocyclopropane-1-carboxylic acid(ACC) treatments in B.napus.

海藻糖-6-磷酸合成酶(TPS)在植物蔗糖代谢和生长发育中发挥重要作用。但迄今为止,对其相关的调控机制知之甚少,已有认识主要基于对模式植物拟南芥的研究。橡胶树乳管是以蔗糖为原料进行橡胶生物合成的一种功能特化细胞,橡胶烃占其细胞质(胶乳)干物质的90％以上,推测TPS 基因可能参与胶乳蔗糖代谢和产胶调控。发现橡胶树基因组上共有14 个TPS 基因(HbTPS),其中4个归为I 类(HbTPS1～4)
