Cellulase Activity, Endogenous Abscisic Acid, and Ethylene in Four Citrus Cultivars during Maturation.
At maturity, the fruit of two early maturing orange cultivars, Hamlin and Pineapple (Citrus sinensis [L.] Osbeck), contained more ethylene and abscisic acid than the late maturing Valencia and Lamb Summer (C. sinensis [L.] Osbeck) cultivars. Ethylene (up to 95 nl/l in internal atmosphere) and abscisic (50 mug/kg dry weight flavedo) increased most rapidly in Pineapple, leading to increased cellu...
متن کاملInteractions between abscisic acid and ethylene signaling cascades.
We screened for mutations that either enhanced or suppressed the abscisic acid (ABA)-resistant seed germination phenotype of the Arabidopsis abi1-1 mutant. Alleles of the constitutive ethylene response mutant ctr1 and ethylene-insensitive mutant ein2 were recovered as enhancer and suppressor mutations, respectively. Using these and other ethylene response mutants, we showed that the ethylene si...
متن کاملThe reciprocal regulation of abscisic acid and ethylene biosyntheses.
Ethylene and abscisic acid (ABA) have compact effects on plant development and stress responses. It is not well understood about the mechanism of ABA modulation in ethylene biosynthesis. In our recent research, HY5-AtERF11 regulon was evidenced to connect the ABA action and ethylene biosynthesis. In this paper, by analyzing the expression of ABA biosynthesis genes and the ABA concentration in e...
متن کاملPlant water stress: Associations between ethylene and abscisic acid response
Agriculture is severely impacted by water stress due either to excess (hypoxia/anoxia) or deficit of water availability. Hypoxia/anoxia is associated with oxygen (O2) deficiency or depletion, inducing several anatomical, morphological, physiological, and molecular changes. The majority of these alterations are adaptive mechanisms to cope with low O2 availability; among them, alterations in shoo...
متن کاملAuxin-induced ethylene triggers abscisic acid biosynthesis and growth inhibition.
The growth-inhibiting effects of indole-3-acetic acid (IAA) at high concentration and the synthetic auxins 7-chloro-3-methyl-8-quinolinecarboxylic acid (quinmerac), 2-methoxy-3,6-dichlorobenzoic acid (dicamba), 4-amino-3,6, 6-trichloropicolinic acid (picloram), and naphthalene acetic acid, were investigated in cleavers (Galium aparine). When plants were root treated with 0.5 mM IAA, shoot epina...
