Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized provide defensive functions and regulate defense signaling pathways safeguard plants against herbivores. Herbivore injury initiates complex reactions which ultimately lead synthesis accumulation of PSMs. The biosynthesis these is regulated by the interplay molecules comprising phytohormones. volatile released upon attack capable directly inducing or priming hormonal pathways. Secondary enable quickly detect attacks respond a timely way rapidly changing scenario pest environment. Several studies suggested that potential for adaptation and/or resistance insect herbivores limited. These cause direct toxicity pests, stimulate antixenosis mechanisms herbivores, and, recruiting natural enemies, indirectly protect plants. Herbivores adapt up/down regulation sensory genes, sequestration detoxification toxic metabolites. PSMs modulate multi-trophic interactions involving host plants, enemies pollinators. Although role plant-pollinator has been little explored, reports suggest both pollinators mutually benefited. Molecular insights into regulatory proteins genes involved will pave metabolic engineering biosynthetic pathway intermediates improving plant tolerance This review throws light on modulating interactions, contributing knowledge plant-herbivore their management an eco-friendly sustainable manner.

Biostimulants on Crops: Their Impact under Abiotic Stress Conditions

Horticulturae, Год журнала: 2022, Номер 8(3), С. 189 - 189

Опубликована: Фев. 22, 2022

Biostimulants are agronomic tools that have been gaining importance in the reduction of fertilizer applications. They can improve yield cropping systems or preventing crop losses under abiotic stresses. be composed organic and inorganic materials most components still unknown. The characterization molecular mechanism action biostimulants obtained using omics approach, which includes determination transcriptomic, proteomic, metabolomic changes treated plants. This review reports an overview biostimulants, taking stock on recent studies contributing to clarify their mechanisms. provide overall evaluation a crop’s response, connecting with physiological pathways activated performance without stress conditions. multiple responses plants must correlated phenotype changes. In this context, it is also crucial design adequate experimental plan statistical data analysis, order find robust correlations between biostimulant treatments performance.

The Application of Arbuscular Mycorrhizal Fungi as Microbial Biostimulant, Sustainable Approaches in Modern Agriculture

Plants, Год журнала: 2023, Номер 12(17), С. 3101 - 3101

Опубликована: Авг. 29, 2023

Biostimulant application can be considered an effective, practical, and sustainable nutritional crop supplementation may lessen the environmental problems related to excessive fertilization. Biostimulants provide beneficial properties plants by increasing plant metabolism, which promotes yield improves quality of crops; protecting against stresses such as water shortage, soil salinization, exposure sub-optimal growth temperatures; promoting via higher nutrient uptake. Other important benefits include enzymatic microbial activities, changing architecture roots, solubility mobility micronutrients, enhancing fertility soil, predominantly nurturing development complementary microbes. are classified microbial, arbuscular mycorrhizae fungi (AMF), plant-growth-promoting rhizobacteria (PGPR), non-pathogenic fungi, protozoa, nematodes, or non-microbial, seaweed extract, phosphite, humic acid, other inorganic salts, chitin chitosan derivatives, protein hydrolysates free amino acids, complex organic materials. Arbuscular mycorrhizal among most prominent biostimulants have role in cultivating better, healthier, more functional foods agriculture. AMF assist acquisition; enhance stress tolerance salinity, drought, heavy metals; reduce erosion. proven a environmentally friendly source supplements. The current manuscript gives many examples potential for production different crops. However, further studies needed better understand effectiveness review focuses on how overcome limitations typical systems improving availability, uptake, assimilation, consequently reducing gap between conventional yields. aim this literature is survey impacts presenting case successful paradigms crops well introducing main mechanisms action biostimulant products.

Survey of the Influences of Microbial Biostimulants on Horticultural Crops: Case Studies and Successful Paradigms

Horticulturae, Год журнала: 2023, Номер 9(2), С. 193 - 193

Опубликована: Фев. 2, 2023

Sustainable farming of horticultural plants has been the focus research during last decade, paying significant attention to alarming weather extremities and climate change, as well pressure biotic stressors on crops. Microbial biostimulants, including plant growth-promoting bacteria (PGPB) arbuscular mycorrhizal fungi (AMF), have proven increase growth via both direct indirect processes, availability uptake nutrients, boosting soil quality, increasing plants’ tolerance abiotic stress overall quality attributes various crops (e.g., vegetables, fruit, herbs). The positive effects microbial biostimulants confirmed so far, mostly through symbiotic interactions in plant–soil–microbes ecosystem, which are considered a biological tool parameters decrease degradation. However, more is needed address future challenges crop production revealing mechanisms action identifying response patterns products. present review aims most up-to-date results regarding practical applications species, case studies successful paradigms for important genera PGPB AMF. Moreover, actions briefly described while remarks also discussed, aiming suggest further needs be addressed establishment sustainable production.

Plant metabolites and signaling pathways in response to biotic and abiotic stresses: Exploring bio stimulant applications

Plant Stress, Год журнала: 2024, Номер 12, С. 100454 - 100454

Опубликована: Март 29, 2024

Plants are constantly exposed to a wide array of complex interactions involving various environmental factors, leading disruptions in their metabolic processes and incurring physiological costs when faced with biotic abiotic stress. In response these stimuli, plants have developed diverse signaling mechanisms adapt the prevailing conditions. equipped different pathways undergo changes at transcriptomic level survive stress stimuli. The divided into four major subsections: signal perception, transduction, regulation gene expression responses. Transcription factors (TFs) play crucial role organization defense by regulating downstream expression. Primary metabolites (PMs) Secondary (SMs) represent fundamental compounds involved plant mechanisms. These extracts promising method increasing tolerance stresses can be used as biostimulants. This review aimed elucidate contributions PMs SMs reactions, well biosynthesis pathways. Additionally, interplay between was discussed. molecular physiology responses stimuli via pathway described this research. Ultimately, were introduced bio stimulants that mitigate adverse effects stresses.
