Melatonin as a Key Factor for Regulating and Relieving Abiotic Stresses in Harmony with Phytohormones in Horticultural Plants — a Review

Journal of soil science and plant nutrition, Journal Year: 2023, Volume and Issue: 24(1), P. 54 - 73

Published: Dec. 26, 2023

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

This study was conducted from 2021–2022 solar greenhouse under artificially controlled conditions. We determined biomass, agronomic indexes, photosynthetic parameters, three treatments: normal supply (CK), mild drought (LD), (HD). The results revealed that inhibited aboveground belowground growth compared with CK; yield decreased increasing drought. net rate, stomatal conductance, transpiration rate leaves significantly stress. leaves’ intercellular CO2 concentration (Ci) up to 50 days after transplanting but increased 75 transplanting. zeatin riboside (ZR) indole-3-acetic acid (IAA) contents were lower tubers LD HD treatments CK, whereas abscisic (ABA) content higher.

Published: May 7, 2024

The post-harvest phase of potato tuber dormancy and sprouting are essential in determining the economic value. intricate transition from to active growth is influenced by multiple factors, including environmental carbohydrate metabolism, hormonal regulation. Well-established factors such as temperature, humidity, light play pivotal roles these processes. However, recent research has expanded our understanding encompass other novel influences magnetic fields, cold plasma treatment, UV-C irradiation. Hormones like abscisic acid (ABA), gibberellic (GA), cytokinins (CK), auxin, ethylene (ETH) act crucial messengers, while brassinosteroids (BRs) have emerged key modulators sprouting. In addition, jasmonates (JAs), strigolactones (SLs), salicylic (SA) also regulate This review article delves into study sprouting, emphasizing impact conditions, It explores how various affect Additionally, it highlights role carbohydrates interplay, particularly BRs. underscores complexity interactions their importance optimizing for agricultural practices.
