FUZHOU， April 8 (Xinhua) -- Chinese researchers have recently discovered the formation mechanism behind self-pollination in cultivated tomatoes， providing valuable insights for increasing tomato yield.
官网-源高海种苗有限公司企业-福环威干果有限公司企业-汇洁全水产有限公司Researchers from the Fujian Agriculture and Forestry University have found that tomatoes can alter the structure of floral organs by regulating the development of trichomes in themselves， thus adopting a self-pollination method to enhance their fruiting rates.
Domesticated tomatoes achieve this anatomically by forming a cone around the male anthers， which ensures that pollen can easily reach the stigma. The anther cone is held together by a dense network of hairs called zipper trichomes.
Researchers identified a set of homeodomain-leucine zipper (HD-ZIP) genes that regulate the formation of these trichomes. Simultaneously， these genes regulate the length of the female style，电脑外设 allowing coordinated development of a self-pollinating reproductive structure.
In agriculture， self-pollination in plants leads to higher fruiting rates and ensures the inheritance of excellent traits， making it one of the key objectives in crop modification for humanity， said Wu Minliang， a researcher of the study.
The research findings was published in the journal Science. ■电脑外设
