Flower abscission
WebOct 15, 2024 · Ethylene is a gaseous phytohormone that controls various biological processes including growth, flowering, fruit ripening, abscission, and senescence ( Seesangboon et al., 2024 ). Plant flowers are very sensitive to the presence of ethylene, which participates directly in the abscission and senescence of plant flowers ( Kamiab … Webformation of abscission zone cells that surround the vascular tissue and inner cortex (Goren and Hubennan 1976; Greenberg et a1 1975). Cells of the AZ-C undergo numerous anatomical changes that lead to abscission. Prior to the onset of abscission, the cell layers that will be involved in the abscission process can readily be

WebMar 1, 1993 · Shade reduced pod numbers and the reductions were due to both increased flower and pod abscission and fewer flowers per plant. Both the number of nodes on the main stem and flowers per node were affected by the shade. Shade during any part of the R1 to R6 period reduced pod numbers in the greenhouse. These data indicate that … WebMar 31, 2024 · NaJAZh had been found to regulate a subset of defense response genes to resist herbivores and spontaneous leaf necrosis, while NaJAZd protein was essential for counteracting flower abscission in Nicotiana attenuata plants [25,26]. The PnJAZ1 confers moss salinity tolerance through the abscisic acid signaling pathway .
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 ... WebFeb 16, 2024 · Flower senescence is commonly enhanced by the endogenous hormone ethylene and suppressed by the gibberellins (GAs) in plants. However, the detailed mechanisms for the antagonism of these hormones during flower senescence remain elusive. ... It is typically characterized by wilting, discoloration, and even abscission due …
WebFlowers of fragrant roses such as Rosa bourboniana are ethylene-sensitive and undergo rapid petal abscission while hybrid roses show reduced ethylene sensitivity and delayed abscission. To understand the molecular mechanism underlying these differences, a comparative transcriptome of petal abscission zones (AZ) of 0 h and 8 h ethylene … WebOct 15, 2024 · Exogenous ethephon treatment promoted tea flower abscission and reduced the numbers of tea flowers and flower buds in the tea plantations, which was partly due to ethylene production and inducibility of antioxidant enzymes.
