Abscisic Acid Levels during Early Seed Development in Sechium edule Sw.
The time-course growth of single tissues in pollinated and unpollinated ovules of Sechium edule Sw. is described in relation to the endogenous levels of abscisic acid. Quantitation of abscisic acid (ABA) in the minute amounts of material obtained after ovule dissection has been performed by using a highly specific and sensitive solid-phase radioimmunoassay based on a monoclonal antibody raised ...
متن کاملProgrammed cell death of the nucellus during Sechium edule Sw. seed development is associated with activation of caspase-like proteases.
The nucellus is a maternal tissue that embeds and feeds the developing embryo and secondary endosperm. During seed development, the cells of the nucellus suffer a degenerative process soon after fertilization as the cellular endosperm expands and accumulates reserves. Nucellar cell degeneration has been considered to be a form of developmentally programmed cell death (PCD). It was investigated ...
متن کاملA comparative assessment of morphological and molecular diversity among Sechium edule (Jacq.) Sw. accessions in India
Genetic variation of 36 Sechium edule accessions collected across 12 states in India was assessed using morphological traits and DAMD markers. Eighteen fruit morphological traits (both qualitative and quantitative) were evaluated to confirm the variations in the present collection. Quantitative traits showed major variations with respect to fruit weight (7.85-498.33 g/fruit), fruit length (5.8-...
متن کاملAbscisic Acid levels and seed dormancy.
Dormant seeds from Fraxinus species require cold-temperature after-ripening prior to germination. Earlier, we found that abscisic acid (ABA) will inhibit germination of excised nondormant embryos and that this can be reversed with a combination of gibberellic acid and kinetin. Using Milborrow's quantitative "racemate dilution" method the ABA concentration in 3 types of Fraxinus seed and pericar...
متن کاملExtracts and Fractions from Edible Roots of Sechium edule (Jacq.) Sw. with Antihypertensive Activity
Sechium edule is traditionally used in Mexico as a therapeutic resource against renal diseases and to control high blood pressure. The purpose of this work is to evaluate the antihypertensive effect of the hydroalcoholic extract obtained from the roots of this plant, including its fractions and subfractions, on different hypertension models induced with angiotensin II (AG II). The hydroalcoholi...
