本研究通过对GoPGF基因的功能研究，解析棉花腺体分化和形成的分子机制

This study analyzes the molecular mechanism of cotton gland differentiation and formation by studying the function of GoPGF gene, and provides an important theoretical basis for the research on the regulation of the differentiation and development of other plant gland organs, such as artemisia annua. Compared with the glandless trait controlled by the double recessive gene gl2gl3, Gl2e (GoPGF) is a dominant single gene that controls the presence or absence of glands, and has a very prominent advantage in breeding and utilization. It effectively solves the problem that recessive glandless genes are prone to natural hybridization, resulting in unsafe food consumption. After being transferred to upland cotton varieties, it has no adverse effects on the main agronomic traits of the transferred varieties. The GoPGF gene-transformed cotton strain created in this study provides a valuable resource for the cultivation of cotton varieties with "plants having glands and seeds without glands."

Through the functional study of GoPGF gene, this study analyzes the molecular mechanism of the differentiation and formation of cotton glands, and provides an important theoretical basis for the study of the differentiation and developmental regulation of other plant glands, such as artemisinin glands. Compared with the adenophysical traits controlled by the double recessive gene gl2gl3, Gl2e (GoPGF) is a dominant single gene that controls the presence and absence of glands and has a very prominent advantage in breeding utilization. It effectively solves the problem that recessive glandless gene is prone to natural hybridization and leads to unsafe consumption, and has no adverse effect on the main agronomic traits of the transferred varieties after being transferred to the land cotton varieties. The transGoPGF gene cotton strain created in this study provides valuable resources for the cultivation of cotton varieties with "aglines, seeds and no glands".

Through the functional study of gopgf gene, this study analyzed the molecular mechanism of cotton gland differentiation and formation, and provided an important theoretical basis for the study of differentiation and development regulation of other plant gland organs, such as Artemisia annua gland. Compared with glandular trait controlled by gl2gl3, gl2e (gopgf) is a dominant single gene which controls whether glandular is present or not. It has a very prominent advantage in breeding. It can effectively solve the problem that recessive glandular gene is easy to cross naturally and lead to food insecurity. After being transferred to upland cotton varieties, it has no adverse effect on the main agronomic characters of the transferred varieties. The transgenic cotton lines with gopgf gene created in this study provide valuable resources for the cultivation of "plants with glands, seeds without glands".<br>
