Since the beginning of 21st century, climate change has been pervasive. Such climatic instabilities not only trigger plants' adaptability and survivability in harsh environments, but also sustain spread a broad spectrum pathogens including bacteria, fungi, viruses, that create disease pressure by affecting plant health immune barrier. Salicylic acid (SA) is potent phytohormone signaling molecule plays pivotal roles physio-biochemical processes during development. In addition to its widely known role abiotic stress response, SA vital response biotic stresses through their pathways, molecular interactions, corresponding interactions with other phytohormones like jasmonic acid, ethylene, abscisic etc. this perspective, dictated plethora interacting genes, proteins, transcription factors (TFs). The genes genetic regulators (TFs regulatory proteins) are associated fine-tune activating systemic localized cascade, triggering for pathogenesis-related (PR) phytoalexins, etc., modulate pathogen effectors. way, boosts plant's system acquired resistance (SAR) induced (ISR). addition, gene editing epigenetic regulation SA-responsive valuable innovative tools understand decipher complex SA-involved mechanism future utilities make climate-adaptive plants resistance.

Synergistic Effects of Rhizobacteria and Salicylic Acid on Maize Salt-Stress Tolerance

Plants, Год журнала: 2023, Номер 12(13), С. 2519 - 2519

Maize (Zea mays L.) is a salt-sensitive plant that experiences stunted growth and development during early seedling stages under salt stress. Salicylic acid (SA) major hormone has been observed to induce resistance in plants against different abiotic stresses. Furthermore, growth-promoting rhizobacteria (PGPR) have shown considerable potential conferring salinity tolerance crops via facilitating promotion, yield improvement, regulation of various physiological processes. In this regard, combined application PGPR SA can wide applicability supporting We investigated the impact on attributes maize explored role mitigating effect Three levels were developed (original, 4 8 dS m-1) pots using NaCl. seeds inoculated with salt-tolerant Pseudomonas aeruginosa strain, whereas foliar was given at three-leaf stage. stress adversely affected growth, yield, compared control. However, both individual applications alleviated negative effects improved all measured attributes.

The Multifaceted Role of Jasmonic Acid in Plant Stress Mitigation: An Overview

Plants, Год журнала: 2023, Номер 12(23), С. 3982 - 3982

Опубликована: Ноя. 27, 2023

Plants, being sessile, have developed complex signaling and response mechanisms to cope with biotic abiotic stressors. Recent investigations revealed the significant contribution of phytohormones in enabling plants endure unfavorable conditions. Among these phytohormones, jasmonic acid (JA) its derivatives, collectively referred as jasmonates (JAs), are particular importance involved diverse signal transduction pathways regulate various physiological molecular processes plants, thus protecting from lethal impacts Jasmonic has emerged a central player plant defense against stress alleviating multiple stressors such drought, salinity, vernalization, heavy metal exposure. Furthermore, growth regulator, JA operates conjunction other through cascade balance development stresses. Although studies reported intricate nature biomolecular entity for mitigation stressors, their underlying mechanism biosynthetic remain poorly understood. Therefore, this review offers an overview recent progress made understanding biosynthesis JA, elucidates complexities pathways, emphasizes pivotal role mitigating Moreover, we also discuss current issues future research directions JAs responses.

Salicylic acid alleviates the effects of cadmium and drought stress by regulating water status, ions, and antioxidant defense in Pterocarya fraxinifolia

Frontiers in Plant Science, Год журнала: 2024, Номер 14

Опубликована: Янв. 12, 2024

Introduction Pterocarya fraxinifolia (Poiret) Spach (Caucasian wingnut, Juglandaceae) is a relict tree species, and little known about its tolerance to abiotic stress factors, including drought heavy metal toxicity. In addition, salicylic acid (SA) has been shown have pivotal role in plant responses biotic stresses. Methods The current study focused on evaluating the impact of foliar application SA mediating Caucasian wingnut physiological biochemical responses, growth, relative water content (RWC), osmotic potential (Ψs), quantum yield (Fv/Fm), electrolyte leakage, lipid peroxidation, hydrogen peroxide, antioxidant enzymes, cadmium (Cd; 100 µM) stress, as well their interaction. Moreover, activity (e.g., ascorbate peroxidase, catalase, glutathione reductase, superoxide dismutase activities) stressed trees was investigated. conducted 6-month-old seedlings under controlled environmental conditions greenhouse for 3 weeks. Results discussion Leaf length, RWC, Ψs, Fv/Fm were decreased all treatments, although effect most pronounced. An efficient defense mechanism detected wingnut. SA-treated plants had lower one indicators oxidative when compared non-SA-treated groups, suggesting this Cd combination. Cadmium also changed ion concentrations causing excessive accumulation leaves. These results highlight beneficial function reducing negative effects plants.
