We have found that a major target for effectors secreted by Pseudomonas syringae is the abscisic acid (ABA) signalling pathway. Because of its essential function in plant stress physiology, elucidating the abscisic acid (ABA) signalling pathway holds enormous promise for application in agriculture.

Many ABA signaling components have been identified, but their interconnections and a consensus on the structure of the ABA signaling network have eluded researchers.

Genes upregulated by effector delivery share a 42% over-lap with ABA-responsive genes and are also components of 5:23.

This is the first reported reconstitution of a plant hormone signalling pathway. Abscisic acid (ABA) is a plant hormone.ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure. Loading... Unsubscribe from Jeffrey Hong? In an attempt to determine negative regulators of ABA signaling, we identified mutants, designated enhanced response to ABA3 ( era3 ), that increased the sensitivity of the seed to … A breakthrough in ABA signaling occurred in 2009, i.e. Microarray data identified a prominent group of effector‐induced genes that were associated with ABA biosynthesis and also responses to this plant hormone.

A breakthrough in ABA signaling occurred in 2009, i.e. Several proteins have been reported to function as ABA receptors, and many more are known to be involved in ABA signalling.

We have found that a major target for effectors secreted by Pseudomonas syringae is the abscisic acid (ABA) signalling pathway. It is especially important for plants in the response to environmental stresses, including drought, soil salinity, cold tolerance, freezing tolerance, heat stress and heavy metal ion tolerance. Microarray data identified a prominent group of effector‐induced genes that were associated with ABA biosynthesis and also responses to this plant hormone. This page has been accessed 807 times.

Several proteins have been reported to function as ABA receptors, and many more are known to be involved in ABA signalling. Because of its essential function in plant stress physiology, elucidating the abscisic acid (ABA) signalling pathway holds enormous promise for application in agriculture.

Abscisic Acid.

Signalling of abscisic acid (ABA) in plants is characterized by an amazing number of secondary messengers that are part of the pathway or modulate the specific hormonal responses by interference with other signal transduction chains. Microarray data identified a prominent group of effector-induced genes that were associated with ABA biosynthesis and also responses to this plant hormone. Physiological CO2 elevations activate anion channels in these mutants.

The phytohormone abscisic acid (ABA) regulates the expression of many genes in plants; it has critical functions in stress resistance and in growth and development. The plant hormone abscisic acid (ABA 1) plays important roles in various physiological and developmental processes.Seed maturation and dormancy, and adaptive responses to water deficit, are the two major processes involving ABA signalling (Bray, 1997; McCarty, 1995).ABA levels are elevated in response to developmental or environmental cues produced in such processes.
