AI Article Synopsis
- Ethylene influences petal abscission in roses by decreasing the flower's fresh weight and altering the cell structure in the abscission zone (AZ).
- The study investigated the role of reactive oxygen species (ROS) and related gene expressions in petals and AZ cells when treated with different substances (MOCK, ETH, STS, ETH + STS).
- Results indicated that ethylene promotes ROS accumulation by boosting the expression of certain ROS production genes while inhibiting those that manage ROS scavenging, ultimately leading to petal abscission.
Article Abstract
Petal abscission affects the growth, development, and economic value of plants, but the mechanism of ethylene-ROS-induced petal abscission is not clear. Therefore, we treated roses with different treatments (MOCK, ETH, STS, and ETH + STS), and phenotypic characteristics of petal abscission, changed ratio of fresh weight, morphology of cells in AZ and the expression of were analyzed. On this basis, we measured reactive oxygen species (ROS) content in petals and AZ cells of roses, and analyzed the expression levels of some genes related to ROS production and ROS scavenging. Ethylene promoted the petal abscission of rose through decreasing the fresh weight of the flower, promoting the stacking and stratification of AZ cells, and repressing the expression of . During this process, ethylene induced the ROS accumulation of AZ cells and petals mainly through increasing the expressions of some genes (, , , , , , , , , and ) related to ROS production and repressing those genes (, , , , and ) related to ROS scavenging. In summary, ROS and related regulatory factors involved in ethylene induced petal abscission in roses.
