Understanding the anticipated impact of climate change on agriculture, as well water conservation, is critical to achieving food security. Therefore, during this time and due reduced resources increased demand, it important study water-stress conditions crops. Two successive seasons were carried out through 2021 2022 estimate crop coefficient (Kc) effect abscisic acid red cabbage plants (Brassi...

Bean callus was induced to form roots (tissue differentiation) and vascular nodules (cell differentiation) by lowering the ratio of auxin to cytokinin in the growth medium. Both types of differentiation were inhibited by the addition of abscisic acid (at concentrations greater than I muM) to induction medium. Initiation of differentiation was inhibited, but its subsequent development was not, a...

Stomatal guard cells control CO(2) uptake and water loss between plants and the atmosphere. Stomatal closure in response to the drought stress hormone, abscisic acid (ABA), results from anion and K(+) release from guard cells. Previous studies have shown that cytosolic Ca(2+) elevation and ABA activate S-type anion channels in the plasma membrane of guard cells, leading to stomatal closure. How...

DnaJ proteins are essential co-chaperones involved in abiotic and biotic stress responses. Arabidopsis AtDjA3 gene encodes a molecular co-chaperone of 420 amino acids, which belongs to the J-protein family. In this study, we report the functional characterization of the AtDjA3 gene using the Arabidopsis knockout line designated j3 and the 35S::AtDjA3 overexpression lines. Loss of AtDjA3 functio...

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). Since the discovery of its structure, advances have been made in understanding ABA metabolism, synthesis, and hormone-responsi...

Abscisic acid (ABA) is a growth regulatory substance that plays an important role in various processes the cell, such as plant adaptation to environmental threats, seed development, dormancy, budding, and fruit ripening. Another of abscisic increased antioxidant capacity, total phenol content, carotenoid, anthocyanin content. The content bioactive compounds antioxidants parameter quality can de...

Abstract The aim of this research was to evaluate the effect abscisic acid (ABA) on gas exchange and activity antioxidant enzymes Ormosia arborea (Vell.) Harms seedlings under water deficit its influence recovery potential seedlings. experiment conducted using four treatments, being daily irrigation or restriction without with 10 μM ABA. Seedlings + ABA showed greater adjustment drought, when r...

In the current study, a simple cryopreservation method (desiccation) was applied to Corylus avellana L. callus. Accordingly, effects of abscisic acid (ABA) concentration, pretreatment duration on MS medium containing ABA + 10% sucrose, and storage length in liquid nitrogen (LN) callus survival rate were investigated. Calli’s assessed 8 weeks after exiting from LN. Callus significantly affected ...
