棉花是集棉、油、粮、饲多位一体的新型高效作物。棉籽是棉花生产中重要的副产品。棉籽富含蛋白和油脂，所含的植物蛋白与大豆类似，氨基酸结构合理；含油量更是高达35%以上，能与花生、油菜相媲美，且棉籽油中的不饱和脂肪酸含量较高，特别是亚油酸含量极高，有益人类心血管健康，是一种优质的植物油资源。但是，由于棉籽中有毒物质棉酚的存在，极大的限制了棉籽的综合利用。棉酚等倍半萜醛类物质积累在腺体中，无腺体棉地上部分不含棉酚。腺体是植物次生代谢物合成积累的主要器官，深入解析棉花腺体分化和形成的分子机制，可为其他药用植物腺体器官的分化发育调控的研究提供重要的理论基础。此外，通过培育“植株有腺体，种子无腺体”的棉花新种质，有效的去除种子中的棉酚，而保留植株中其他组织中的棉酚，保持植株自身对虫、病的抗性，对于提高棉籽的综合利用价值具有重大的经济效益。

Cotton is a new and efficient crop, which integrates cotton, oil, grain and feed. Cottonseed is an important by-product in cotton production. Cottonseed is rich in protein and oil. The plant protein contained in cottonseed is similar to soybean, and the structure of amino acid is reasonable. The oil content is more than 35%, which is comparable to peanut and rape. Moreover, the content of unsaturated fatty acid in cottonseed oil is high, especially the content of linoleic acid, which is beneficial to human cardiovascular health. It is a high-quality plant oil resource. However, due to the existence of gossypol in cottonseed, the comprehensive utilization of cottonseed is greatly limited. Gossypol and other sesquiterpene aldehydes were accumulated in glands, but gossypol was not found in the aboveground part of glandless cotton. Gland is the main organ of plant secondary metabolite synthesis and accumulation. The analysis of the molecular mechanism of cotton gland differentiation and formation can provide an important theoretical basis for the study of differentiation and development regulation of gland organs of other medicinal plants. In addition, it is of great economic benefit to improve the comprehensive utilization value of cottonseed by cultivating a new cotton germplasm with "plants with glands and seeds without glands", which can effectively remove gossypol from seeds, and retain gossypol from other tissues of the plant, and maintain the resistance of the plant to insects and diseases.<br>
