Microarray analysis of the abscission-related transcriptome in the tomato flower abscission zone in response to auxin depletion.
The abscission process is initiated by changes in the auxin gradient across the abscission zone (AZ) and is triggered by ethylene. Although changes in gene expression have been correlated with the ethylene-mediated execution of abscission, there is almost no information on the molecular and biochemical basis of the increased AZ sensitivity to ethylene. We examined transcriptome changes in the t...

متن کاملPistillate Flower Abscission - 1990
Evaluation of the pistillate flower abscission (PFA) potential of UC-67-13 and UC-67-11 was continued at two sites. At a high PFA site UC-67-13 PFA was only moderately lower than Serr for the third year. UC-67-11 demonstrated low PFA potential for a seconq year at this site. Higher PFA potential of UC-67-13 than UC-67 -11 was also found at a second site for a second year. No further evaluation ...
متن کاملPistillate Flower Abscission (pfa)
PFA was not different with shaded vs. exposed limbs of the same trees nor between shaded interior trees and outside ones with high light exposure. Tehama trees expressed lower PFA than adjacent Serre PFA of Tehama was also low at a site where Serr trees (removed 1982) had very high drop the previous three years. Fruitfulness of all monitored limbs in 1982 ranged from 6 to 97% and the earlier co...
متن کاملAbscission responses to moisture stress, auxin transport inhibitors, and ethephon.
The three abscission-inducing agents - water stress, Ethephon, and auxin transport inhibitors-acted synergistically to promote leaf fall in cotton (Gossypium hirsutum L.). However, the synergism was primarily between stress and Ethephon. Auxin transport inhibitors did not promote the effect of stress alone, only promoted the effect of Ethephon in well watered plants and gave a very small promot...
