Plant Secondary Metabolites: The Weapons for Biotic Stress Management

Metabolites, Journal Year: 2023, Volume and Issue: 13(6), P. 716 - 716

Published: May 31, 2023

The rise in global temperature also favors the multiplication of pests and pathogens, which calls into question food security. Plants have developed special coping mechanisms since they are sessile lack an immune system. These use a variety secondary metabolites as weapons to avoid obstacles, adapt their changing environment, survive less-than-ideal circumstances. Plant include phenolic compounds, alkaloids, glycosides, terpenoids, stored specialized structures such latex, trichomes, resin ducts, etc. Secondary help plants be safe from biotic stressors, either by repelling them or attracting enemies, exerting toxic effects on them. Modern omics technologies enable elucidation structural functional properties these along with biosynthesis. A better understanding enzymatic regulations molecular aids exploitation modern pest management approaches biopesticides integrated management. current review provides overview major plant that play significant roles enhancing stress tolerance. It examines involvement both indirect direct defense mechanisms, well storage within tissues. Additionally, this explores importance metabolomics elucidating significance application metabolic engineering breeding for resistance is discussed, sustainable

Microorganisms in Plant Growth and Development: Roles in Abiotic Stress Tolerance and Secondary Metabolites Secretion

Microorganisms, Journal Year: 2022, Volume and Issue: 10(8), P. 1528 - 1528

Published: July 28, 2022

Crops aimed at feeding an exponentially growing population are often exposed to a variety of harsh environmental factors. Although plants have evolved ways adjusting their metabolism and some also been engineered tolerate stressful environments, there is still shortage food supply. An alternative approach explore the possibility using rhizosphere microorganisms in mitigation abiotic stress hopefully improve production. Several studies shown that rhizobacteria mycorrhizae organisms can help tolerance by enhancing plant growth; stimulating production phytohormones, siderophores, solubilizing phosphates; lowering ethylene levels; upregulating expression dehydration response antioxidant genes. This article shows secretion secondary metabolites as additional mechanism employed against stress. The understanding these mechanisms will efficacy plant-growth-promoting microorganisms.

Cobalt: An Essential Micronutrient for Plant Growth?

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

Published: Nov. 16, 2021

Cobalt is a transition metal located in the fourth row of periodic table and neighbor iron nickel. It has been considered an essential element for prokaryotes, human beings, other mammals, but its essentiality plants remains obscure. In this article, we proposed that cobalt (Co) potentially micronutrient plants. Co growth many lower plants, such as marine algal species including diatoms, chrysophytes, dinoflagellates, well higher family Fabaceae or Leguminosae. The to leguminous attributed role nitrogen (N) fixation by symbiotic microbes, primarily rhizobia. integral component cobalamin vitamin B12, which required several enzymes involved N2 fixation. addition symbiosis, group fixing bacteria known diazotrophs able situate plant tissue endophytes closely associated with roots economically important crops, barley, corn, rice, sugarcane, wheat. Their action provides crops macronutrient N. proteins, participating metabolism. Plants may exhibit deficiency if there severe limitation supply. Conversely, toxic at concentrations. High levels result pale-colored leaves, discolored veins, loss leaves can also cause anticipated advance omics, constitute proteins specific metabolism will be exclusively revealed. confirmation enrich our understanding mineral nutrition improve practice crop production.

Arsenic-Induced Oxidative Stress and Antioxidant Defense in Plants

Stresses, Journal Year: 2022, Volume and Issue: 2(2), P. 179 - 209

Published: April 2, 2022

The non-essential metalloid arsenic (As) is widely distributed in soil and underground water of many countries. Arsenic contamination a concern because it creates threat to food security terms crop productivity safety. Plants exposed As show morpho-physiological, growth developmental disorder which altogether result loss productivity. At physiological level, As-induced altered biochemistry chloroplast, mitochondria, peroxisome, endoplasmic reticulum, cell wall, plasma membrane causes reactive oxygen species (ROS) overgeneration damage through disintegrating the structure lipids, proteins, DNA. Therefore, plants tolerance ROS-induced oxidative stress vital strategy for enhancing plants. having enhanced antioxidant defense system greater toxicity. Depending upon plant diversity (As hyperaccumulator/non-hyperaccumulator or tolerant/susceptible) mechanisms accumulation, absorption toxicity response may differ. There can be various management practices such as exogenous application nutrients, hormones, antioxidants, osmolytes, signaling molecules, different chelating agents, microbial inoculants, organic amendments etc. effective against information gap understanding mechanism (damage response) This review presents uptake accumulation plants, responses under stress, ROS generation response, approaches from available literatures will make date knowledge, knowledge future guideline worked out development tolerant cultivars.
