(Naphthalene-2-sulfonyl)-piper

萘乙酸（naphthalene acetic acid，NAA）

　　 一种人工合成的具有与生长素类似生理效应的有机物。有效成分为α -NAA，分子式 C12 H10 O2 ，白色结晶，不溶于水，溶于酒精等有机溶剂，其钠盐溶于水，效应与 NAA相同，但应用浓度较高。生产容易，活性强，为农业及园艺上使用最广泛的人工合成生长素之一。它可以促进发芽、单性结实及花芽形成（波罗），抑制器官脱落以及刺激插枝生根等。由于生根量少且较粗，故宜与吲哚丁酸（刺激插枝生根数目多且较细）共用。

A genetically encoded fluorescent amino acid（基因编码的荧光氨基酸）

. The fluorescent amino acid 2-amino-3-(5-(dimethylamino) naphthalene-1-sulfonamide)propanoic acid (dansylalanine) was genetically encoded in Saccharomyces cerevisiae by using an amber nonsense codon and corresponding
