Near the time of abscission, PFA-type flowers show signs of necrosis at the tips of the stigma, in the integument, and throughout the placental evaginations (Catlin and Polito, 1989). Flower abscission due to PFA is clearly distinguishable from abscission that results from lack of ...

WebJA treatment delayed flower opening as well as petal abscission by more than 24h in R. bourboniana and also increased transcription of the JA pathway genes, unlike ethylene. The strong and rapid reduction of the entire JA pathway in the AZ in R. bourboniana flowers, prior to flower opening and petal abscission, suggests a negative role for JA ... WebAbstract Abscission of floral organs from the main body of a plant is a dynamic process that is developmentally and environmentally regulated. In the past decade, genetic studies in Arabidopsis have identified key signaling components and revealed their interactions in the regulation of floral organ abscission.
