A novel calix[4]arene,based fluorescent chemosensor bearing a 2,aminopyridine moiety and a naphthalenic fluorophore was synthesized The chemical structure of the product was elucidated by FT,IR, MS,FAB, NMR and elemental analyses. Then, the properties and identification mechanism of the synthesized chemosensor were investigated. The results show that the chemosensor exhibits selective fluorescent quenching in the presence of aromatic organic acid in acetonitrile solution, and that the binding ability of the chemosensor with organic acid is in the order of p,cyanic,benzyl acid＞p,chloric,benzyl acid＞p,methoxyl,benzyl acid＞benzyl acid.

水稻是最重要的粮食作物之一,也是目前植物分子生物学研究的重要模式生物之一。水稻基因功能的鉴定不仅可以为水稻育种提供有力的理论指导,而且也是我们了解植物生长发育的最有效途径。正是由于水稻本身的特殊性,人们对水稻优良种质的筛选和各类生物学过程机理的研究从未停止过,其中包括稻米品质研究。水稻胚乳中蛋白质含量又恰恰是稻米品质重要组成部分,所以水稻蛋白质含量遗传研究作为水稻品质育种的基础,十分重要。水稻蛋白
