The Apple Mitogen-Activated Protein Kinase MdMAPK6 Increases Drought, Salt, and Disease Resistance in Plants

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(7), P. 3245 - 3245

Published: March 31, 2025

As sessile organisms, plants are exposed to a variety of environmental stresses caused by biotic and abiotic factors during their life cycle; as result, have evolved complex defense mechanisms cope with these stresses, among which the mitogen-activated protein kinase cascade signaling pathway is particularly critical. This study focused on MdMAPK6, specific gene in Malus domestica, illuminate its functions stress responses. MdMAPK6 was successfully cloned from apple shown respond various stressors, including drought, salt, abscisic acid. Overexpressing calli resulted enhanced resistance Botryosphaeria dothidea. Ectopic expression Arabidopsis thaliana Pseudomonas syringae pathovar tomato DC3000. These results indicated that apples traditional kinase, plays an important role both stresses.

Abstract A field experiment was conducted during the 2022-2023 season in an agricultural Babil Governorate, Iraq, with aim of understanding role MAPKs genes enhancing faba bean resistance to different salinity levels. The carried out using a Randomized Complete Block Design (RCBD) split-plot arrangement three replications. main plots included levels saline water irrigation (2, 4, and 8 dS/m), while subplots consisted genotypes (local, Turkish, Spanish). results indicated that third level (8 dS/m) significantly increased content SOD, CAT, GR enzymes, average values 83.78, 60.77, 34.01 U/min/g FW, respectively. On other hand, first (2 showed superiority APX enzyme value 75.84 FW. Turkish genotype outperformed APX, 76.84, 59.04, 52.74, Meanwhile, Spanish excelled leaf area, number seeds per plant, total yield, averages 2437.58 cm 2 , 29.69 2.48 tons hectare, local 500-seed weight 503.54 grams. Additionally, significant interactions were observed between study factors across all traits under investigation. revealed elevated enhance activity antioxidant enzymes beans, which may contribute their salinity. It also found respond differently changes increase content, productive such as yield. These findings highlight importance selecting appropriate cope conditions agriculture.

A close-up of regulatory networks and signaling pathways of MKK5 in biotic and abiotic stresses

Critical Reviews in Biotechnology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 18

Published: May 26, 2024

Mitogen-activated protein Kinase 5 (MKK5) is a central hub in the complex phosphorylation chain reaction of kinases (MAPK) cascade, regulating plant responses to biotic and abiotic stresses. This review manuscript aims provide comprehensive analysis regulatory mechanism MKK5 involved stress adaptation. will delve into intricate post-transcriptional post-translational modifications MKK5, discussing how they affect its expression, activity, subcellular localization response signals. We also discuss integration signaling pathways, orchestrating immunity against pathogens modulating role stresses, such as: drought, cold, heat, salinity, through phytohormonal pathways. Furthermore, we highlight potential applications for engineering stress-resilient crops future perspectives that may pave way studies. valuable insights mechanisms underlying regulation, bridge gap from numerous previous findings, offer firm base knowledge roles, involvement environmental regulation.

Plant Responses and Adaptations to Salt Stress: A Review

Horticulturae, Journal Year: 2024, Volume and Issue: 10(11), P. 1221 - 1221

Published: Nov. 18, 2024

Salinity poses a significant environmental challenge, limiting plant growth and development. To cultivate salt-tolerant plants, it is crucial to understand the physiological, biochemical, molecular responses adaptations salt stress, as well explore natural genetic resources linked tolerance. In this review, we provide detailed overview of mechanisms behind morphological physiological triggered by including damage disturbance cell osmotic potentials ion homeostasis, lipid peroxidation, suppression photosynthesis growth. We also describe that confer tolerance in such adjustments, reactive oxygen species (ROS) scavenging, photosynthetic responses, phytohormone regulation, regulation. Additionally, summarize salt-stress sensing signaling pathways, gene regulatory networks, salt-tolerance plants. The key pathways involved signal perception transduction, Ca2+-dependent protein kinase (CDPK) cascades, overly sensitive (SOS) pathway, abscisic acid (ABA) are discussed, along with relevant salt-stress-responsive genes transcription factors. end, important issues challenges related for future research addressed. Overall, review aims essential insights cultivation breeding crops fruits.
