Abscission: Role of Abscisic Acid [PDF]
Plant Physiology, 1969 The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase.

Plant Physiology, 2010 Abscisic acid (ABA), a sesquiterpenoid phytohormone, was first discovered in the 1960s, and has since been found to be a key regulator of such diverse processes as dormancy, germination, seed development, and responses to biotic and abiotic stress ([Cutler et al., 2010][1]).

Animal Research and One Health, EarlyView., 2023 In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this

Response of Cultured Maize Cells to (+)-Abscisic Acid, (-)-Abscisic Acid, and Their Metabolites [PDF]
Plant Physiology, 1994 The metabolism and effects of (+)-S- and (-)-R-abscisic acid (ABA) and some metabolites were studied in maize (Zea mays L. cv Black Mexican Sweet) suspension-cultured cells. Time-course studies of metabolite formation were performed in both cells and medium via analytical high-performance liquid chromatography.

Action of Natural Abscisic Acid Precursors and Catabolites on Abscisic Acid Receptor Complexes [PDF]
Plant Physiology, 2011 AbstractThe phytohormone abscisic acid (ABA) regulates stress responses and controls numerous aspects of plant growth and development. Biosynthetic precursors and catabolites of ABA have been shown to trigger ABA responses in physiological assays, but it is not clear whether these are intrinsically active or whether they are converted into ABA in ...

Control of abscisic acid synthesis [PDF]
Journal of Experimental Botany, 2000 The abscisic acid (ABA) biosynthetic pathway involves the formation of a 9-cis-epoxycarotenoid precursor. Oxidative cleavage then results in the formation of xanthoxin, which is subsequently converted to ABA. A number of steps in the pathway may control ABA synthesis, but particular attention has been given to the enzyme involved in the oxidative ...

Agricultural and Biological Chemistry, 1970 Oxidation of 2-cis-α-ionylidene-ethanol (II) with active MnO2 afforded a mixture of 2-cis and 2-trans-α-ionylideneacetaldehydes (III and IV). Reduction of methyl epoxy-α- and -β-ionylideneacetates (Vb, Xb XXIb and XXIIb) with LiAlH4 gave the diols (VI, XI, XXIII and XXIV).

Abscisic Acid and Stomatal Regulation [PDF]
Plant Physiology, 1972 The closure of stomata by abscisic acid was examined in several species of plants through measurements of CO(2) and H(2)O exchange by the leaf. The onset of closure was very rapid, beginning at 3 minutes from the time of abscisic acid application to the cut base of the leaf of corn, or at 8 or 9 minutes for bean, Rumex and sugarbeet; rose leaves were ...
