摘　　要：天然彩棉是纤维含有天然色素类物质的特殊类型棉花。目前公认的商用天然彩棉主要是棕色和绿色两大类,颜色比较单一。为了丰富天然彩棉的品种和满足人们对色彩的需求,研究者们对彩色棉纤维色素的成分以及形成机理进行了多方面研究。该文以天然彩色棉纤维为论述对象,详细介绍了彩色棉纤维的发育、色素沉积和色素成分。通过对色素成分的研究,发现彩棉纤维色素与植物中重要的次生代谢途径——类黄酮生物合成途径相关。因此,对该途径中的结构基因和调节因子综合已有研究结果展开论述,这为利用基因工程技术改良和培育彩色棉新品种提供全面的理论基础,具有很好的参考价值。Naturally colored cotton is a special type cotton,which contains pigment in cotton fiber. Up to date,there are only two kinds of commercial colored cotton varieties in the world,brown cotton and green cotton. In order to breed new colored varieties and meet people’s need for different colors,many researches on pigment in naturally colored cotton fiber were studied. This review summarizes the molecular mechanism of the pigment formation of naturally colored cotton fiber. In this paper,the fiber development,pigment accumulation and composition of colored cotton are introduced in detail. The results of the composition analyzed in the colored fiber showed that the pigment was related to the flavonoid biosynthesis pathway,which was the important secondary metabolites pathway. Therefore,the structural genes and transcription regulator factors of the flavonoid biosynthesis pathway are mainly reviewed. It may provide important theory basis for colored cotton breeding and improvement by using the genetic engineering technology.
