项目摘要

Aluminum (Al) ion inhibits sugar uptake which leads to the inhibition of water uptake as well as cell elongation. Inhibition of sugar uptake by Al seems to be compensated by the stimulation of translocation of photosynthates. Novel strategy for Al tolerance differing from the known strategy based on the release of organic acid anions was found. Higher sterols in plasma membrane lipid layer of root-tip were demonstrated to be the cause of Al tolerance. Genomic and genetic approaches in Arabidopsis revealed that acid and Al tolerances were co-regulated by the same signal transduction pathway, but with the distinct functional genes for tolerance. Comparative microarray analysis showed that common alterations involved in the metabolisms of sugars and lipids contributed to P recycling. It was suggested that responses in flavonoids synthesis were specific in leguminous plants.
铝 (Al) 离子抑制糖的摄取,从而抑制水的摄取以及细胞伸长。铝对糖吸收的抑制似乎可以通过刺激光合产物的易位来补偿。发现了与基于有机酸阴离子释放的已知策略不同的新的铝耐受策略。根尖质膜脂质层中较高的甾醇被证明是铝耐受的原因。拟南芥的基因组和遗传学方法表明,酸和铝耐受性是由相同的信号转导途径共同调节的,但具有不同的耐受功能基因。比较微阵列分析表明,糖和脂质代谢中常见的改变有助于磷的回收。有人认为类黄酮合成的反应在豆科植物中是特异的。
