Abstract The classic plant growth‐promoting phytohormone cytokinin has been identified and established as a mediator of pathogen resistance in different species. However, the effect structurally cytokinins appears to vary may regulate diverse mechanisms establish resistance. Hence, we comparatively analysed impact six adenine‐ phenylurea‐type on well‐established pathosystem Nicotiana tabacum ‐ Pseudomonas syringae . efficiency effects was evaluated based impacts host defence response by scoring infection symptoms direct assessment proliferation planta To identify common cytokinin‐specific components involved effects, transcriptome profiling targeted metabolomics were conducted leaves treated with cytokinins. We observed clearly potentials tested either suppressing or proliferation. Gene regulation metabolite analyses revealed cytokinin‐type specific components, such salicylic acid related signalling, expression PR proteins, specialised metabolism. Cytokinins also strongly affected cell physiological parameters, remarkable decrease amino pools. this study provides comparative information mediating one well‐studied insights into mediated molecules. This is particularly relevant for studies function other phytohormones compounds interacting activities context infections stress scenarios, considering present plants.

Plants must effectively respond to various environmental stimuli achieve optimal growth. This is especially relevant in the context of climate change, where drought emerges as a major factor globally impacting crops and limiting overall yield potential. Throughout evolution, plants have developed adaptative strategies for stimuli, with plant hormones reactive oxygen species (ROS) playing essential roles their development. Hormonal signaling maintenance ROS homeostasis are interconnected, indispensable growth, development, stress responses orchestrating diverse molecular during adversities. Nine principal classes phytohormones been categorized: auxins, brassinosteroids, cytokinins, gibberellins primarily oversee developmental growth regulation, while abscisic acid, ethylene, jasmonic salicylic strigolactones main orchestrators responses. Coordination between transcriptional regulation crucial effective responses, stress. Understanding interplay pivotal elucidating mechanisms involved review provides an overview intricate relationship ROS, redox metabolism, nine different plants, shedding light on potential enhancing tolerance sustainable crop production.

Sulfur (S), one of the crucial macronutrients, plays a pivotal role in fundamental plant processes and regulation diverse metabolic pathways. Additionally, it has major function protection against adverse conditions by enhancing tolerance, often interacting with other molecules to counteract stresses. Despite its significance, thorough comprehension how plants regulate S nutrition particularly involvement phytohormones this process remains elusive.

Abstract In reaction to a stimulus, signaling molecules are made, generate response, and then degraded. Nucleotides classically associated with central metabolism nucleic acid biosynthesis, but there number of nucleotides nucleotide derivatives in plants which this simple definition molecule applies whole or at least part.

Bacterial pathogens manipulate host signaling pathways and evade defenses using effector molecules, coordinating their deployment to ensure successful infection. However, host-derived metabolites as signals, critical role in regulating bacterial virulence requires further insights. Effective regulation of virulence, which is essential for pathogenic bacteria, involves controlling factors that enable colonization, defense evasion, tissue damage. This dynamic, influenced by environmental cues including signals from plants like exudates. Plant exudates, comprising diverse compounds released roots tissues, serve rich chemical affecting the behavior associated bacteria. nutrients act molecules are sensed through membrane-localized receptors intracellular response mechanisms review explains how different bacteria detect answer secreted gene expression.

Pathogenesis-related (PR) proteins are critical defense signaling molecules induced by phytopathogens. They play a vital role in plant's pathways and innate immunity, particularly systemic acquired resistance (SAR) serve as key molecular markers of plant defense. Overexpressing PR genes, such chitinase, thaumatin, glucanase, thionin defensin, either individually or combination, have significantly boosted plants' responses against various pathogens. However, regulating the expression these versatile remain only partially understood. Plant hormones like salicylic acid (SA) jasmonic (JA) known for their well-established roles gene to pathogens other stress conditions. genes interact with components hormonal pathways, including receptors (e.g., NPR1 SA signaling), transcription factors MYC2 JA cis-regulating elements W-box), modulate responses. Recent studies highlighted contributions different immunity interactions process crosstalk, which helps coordinate activation. This review provides comprehensive overview proteins, complexity, crosstalk aiming understand improved pathogen resistance.
