Predisposition results from abiotic stresses occurring prior to infection that affect susceptibility of plants to disease. The environment is seldom optimal for plant growth, and even mild, episodic stresses can predispose plants to inoculum levels they would otherwise resist. Plant responses that are adaptive in the short term may conflict with those for resisting pathogens. Abiotic and biotic stress responses are coordinated by complex signaling networks involving phytohormones and reactive…

Combined Abiotic Stresses Repress Defense and Cell Wall Metabolic Genes and Render Plants More Susceptible to Pathogen Infection

The data emphasize that the combination of global warming-associated abiotic stresses such as heat and osmotic stresses makes plants more susceptible to pathogen infection, thus threatening future global food security.

The Effects of Combined Abiotic and Pathogen Stress in Plants: Insights From Salinity and Pseudomonas syringae pv lachrymans Interaction in Cucumber

C cucumber plants exposed to salt stress and thereafter infected with Pseudomonas syringae pv lachrymans were more prone to infection and this effect was determined by changes in the hormonal and redox balance as well as the carboxylate metabolism and activities of some NADPH-generating enzymes.

Defining the combined stress response in wild Arachis

Nematodes and drought are major constraints in tropical agriculture and often occur simultaneously. Plant responses to these stresses are complex and require crosstalk between biotic and abiotic

ABA-Dependent Salt Stress Tolerance Attenuates Botrytis Immunity in Arabidopsis

A regulatory role of ABA is proposed in attenuating Botrytis immunity in this plant under salt stress conditions because abscisic acid levels were already elevated before pathogen infection and application of exogenous ABA substituted for salt-watering in increasing Arabidopsis susceptibility toward B. cinerea infection.

Tailored Responses to Simultaneous Drought Stress and Pathogen Infection in Plants

The effects of combinatorial drought stress and pathogen infection on plants are discussed with an emphasis on the molecular and physiological mechanisms that underpin how plants tolerate simultaneously occurring stresses.

Impact of Concurrent Drought Stress and Pathogen Infection on Plants

The recent studies indicate that concurrent stress conditions lead to the activation of unique combat pathways that are otherwise not elicited under independent stresses, and it is proposed that further efforts should be directed to identify the potential pathways conferring concurrent stress tolerance.

The interaction of plant biotic and abiotic stresses: from genes to the field.

This review aims to characterize the interaction between biotic and abiotic stress responses at a molecular level, focusing on regulatory mechanisms important to both pathways.

Abscisic acid in salt stress predisposition to phytophthora root and crown rot in tomato and chrysanthemum.

Several lines of evidence support ABA as a critical and dominant factor in the salinity-induced predisposition to Phytophthora spp.

The roles of ABA in plant–pathogen interactions

This review presents examples demonstrating the importance of crosstalk between ABA and the key biotic stress phytohormone salicylic acid in determining the outcome of plant–pathogen interactions and discusses future directions for studies of ABA in plant immunity.

Disease resistance or growth: the role of plant hormones in balancing immune responses and fitness costs

Novel insights are addressed on the regulatory roles of the ABA, SA, and auxin in plant resistance to pathogens and the complex interactions among their signal transduction pathways are described.

Global switches and fine-tuning-ABA modulates plant pathogen defense.

This article aims to evaluate and review the reported modes of ABA action on pathogen defense and highlight recent advances in deciphering the complex role of A BA in plant-pathogen interactions.

Antagonism between salicylic and abscisic acid reflects early host-pathogen conflict and moulds plant defence responses.

It is predicted that hormonal perturbations, either induced or as a result of environmental stress, have a marked impact on pathological outcomes, and a mechanistic basis for understanding priming events in plant defence is provided.

Stress Signaling I: The Role of Abscisic Acid (ABA)

This review concentrates on two aspects of how ABA is involved with the adaptation of plants to abiotic stress: (a) the perception of the stress and the resulting ABA response network of

Role of DREB transcription factors in abiotic and biotic stress tolerance in plants

This review intends to focus on the structure, role of DREBs in plant stress signaling and the present status of their deployment in developing stress tolerant transgenic plants.

Abiotic stresses affect Trichoderma harzianum T39-induced resistance to downy mildew in grapevine.

The evidence reported here suggests that exposure of crops to abiotic stress should be carefully considered to optimize the use of resistance inducers, especially in view of future global climate changes.
