Arbuscular mycorrhizal fungi (AMF) establish symbiotic associations with most terrestrial plants. These soil microorganisms enhance the plant’s nutrient uptake by extending root absorbing area. In return, symbiont receives plant carbohydrates for completion of its life cycle. AMF also helps plants to cope biotic and abiotic stresses such as salinity, drought, extreme temperature, heavy metal, diseases, pathogens. For stresses, mechanisms adaptation these are generally linked increased hydromineral nutrition, ion selectivity, gene regulation, production osmolytes, synthesis phytohormones antioxidants. Regarding involved in pathogen resistance including competition colonization sites improvement defense system. Furthermore, have a positive impact on ecosystems. They improve quality aggregation, drive structure bacteria communities, ecosystem stability. Thus, colonized will use more compared without mycorrhizae. this review, we present contribution growth performance stressed environments.

Plant sugars: Homeostasis and transport under abiotic stress in plants

Physiologia Plantarum, Год журнала: 2020, Номер 171(4), С. 739 - 755

Опубликована: Ноя. 20, 2020

The sessile nature of plants' life is endowed with a highly evolved defense system to adapt and survive under environmental extremes. To combat such stresses, plants have developed complex well-coordinated molecular metabolic networks encompassing genes, metabolites, acclimation responses. These modulate growth, photosynthesis, osmotic maintenance, carbohydrate homeostasis. Under given stress condition, sugars act as key players in perception, signaling, are regulatory hub for stress-mediated gene expression ensuring responses adjustment, scavenging reactive oxygen species, maintaining the cellular energy status through carbon partitioning. Several sugar transporters known regulate partitioning signal transduction steps involved perception biotic abiotic stresses. Sugar SUGARS WILL EVENTUALLY BE EXPORTED TRANSPORTER (SWEETs), SUCROSE TRANSPORTERS (SUTs), MONOSACCHARIDE (MSTs) loading unloading well long-distance transport (source sink) besides orchestrating oxidative tolerance.

Plants’ Response Mechanisms to Salinity Stress

Plants, Год журнала: 2023, Номер 12(12), С. 2253 - 2253

Опубликована: Июнь 8, 2023

Soil salinization is a severe abiotic stress that negatively affects plant growth and development, leading to physiological abnormalities ultimately threatening global food security. The condition arises from excessive salt accumulation in the soil, primarily due anthropogenic activities such as irrigation, improper land uses, overfertilization. presence of Na⁺, Cl-, other related ions soil above normal levels can disrupt cellular functions lead alterations essential metabolic processes seed germination photosynthesis, causing damage tissues even death worst circumstances. To counteract effects stress, plants have developed various mechanisms, including modulating ion homeostasis, compartmentalization export, biosynthesis osmoprotectants. Recent advances genomic proteomic technologies enabled identification genes proteins involved salt-tolerance mechanisms. This review provides short overview impact salinity on underlying mechanisms salt-stress tolerance, particularly salt-stress-responsive associated with these aims at summarizing recent our understanding tolerance providing key background knowledge for improving crops' which could contribute yield quality enhancement major crops grown under saline conditions or arid semiarid regions world.

Mitigating Soil Salinity Stress with Gypsum and Bio-Organic Amendments: A Review

Agronomy, Год журнала: 2021, Номер 11(9), С. 1735 - 1735

Опубликована: Авг. 29, 2021

Salinity impedes soil and crop productivity in over 900 million ha of arable lands worldwide due to the excessive accumulation salt (NaCl). To utilize saline soils agriculture, halophytes (salt-tolerant plants) are commonly cultivated. However, most food crops glycophytes (salt-sensitive). Thus, enhance soils, gypsum (CaSO4·2H2O) as well bio-organic (combined use organic materials, such compost straw with inoculation beneficial microbes) amendments have been continuously recognized improve biological, physical chemical properties soils. CaSO4·2H2O regulates exchange sodium (Na+) for calcium (Ca2+) on clay surfaces, thereby increasing Ca2+/Na+ ratio solution. Intracellularly, Ca2+ also promotes a higher K+/Na+ ratio. Simultaneously, furnishes sulfur (S) enhanced growth yield through increased production phytohormones, amino acids, glutathione osmoprotectants, which vital elicitors plants’ responses salinity stress. Likewise, matter carbon content, nutrient cycling, porosity, water holding capacity, enzyme activities biodiversity Overall, integrated application cultivating is highly promising strategy enhancing

MicroRNAs (miRNAs) are a class of non-coding endogenous small RNAs (long 20-24 nucleotides) that negatively regulate eukaryotes gene expression at post-transcriptional level via cleavage or/and translational inhibition targeting mRNA. Based on the diverse roles miRNA in regulating expression, research identification target genes has been carried out, and growing body demonstrated miRNAs act involved various biological functions plants. It an important influence plant growth development, morphogenesis, stress response. Recent case studies indicate miRNA-mediated regulation pattern may improve agronomic properties confer abiotic resistance plants, so as to ensure sustainable agricultural production. In this regard, we focus recent updates their targets responding including low temperature, high drought, soil salinity, heavy metals, well plant-growing development. particular, review highlights achieving desirable traits crops. Herein, main strategies crop improvement were summarized. Furthermore, miRNA-related challenges future perspectives plants have discussed. miRNA-based lays foundation for exploring regulatory mechanism, which aims provide insights into potential form breeding.

Soil salinity has become an increasingly serious problem worldwide, greatly limiting crop development and yield, posing a major challenge to plant breeding. Basic leucine zipper (bZIP) transcription factors are the most widely distributed conserved main regulators controlling various response processes against external stimuli. The bZIP protein contains two domains: highly conserved, DNA-binding alkaline region, diverse zipper, which is one of largest factor families in plants. Plant involved many biological processes, such as flower development, seed maturation, dormancy, senescence, plays important role abiotic stresses salt damage, drought, cold osmotic stress, mechanical ABA signal response. In addition, regulation insect pests pathogen infection through salicylic acid, jasmonic transduction pathways.

The unpredictable climatic perturbations, the expanding industrial and mining sectors, excessive agrochemicals, greater reliance on wastewater usage in cultivation, landfill leachates, are collectively causing land degradation affecting thereby reducing food production globally. Biochar can generally mitigate unfavourable effects brought about by perturbations (drought, waterlogging) degraded soils to sustain crop production. It also reduce bioavailability phytotoxicity of pollutants contaminated via immobilization inorganic and/or organic contaminants, commonly through surface complexation, electrostatic attraction, ion exchange, adsorption, co-precipitation. When biochar is applied soil, it typically neutralizes soil acidity, enhances cation exchange capacity, water holding aeration, microbial activity. Thus, has been was widely used as an amendment ameliorate abiotic/biotic stress. This review discusses addition under certain conditions (salinity, drought, flooding heavy metal stress) improve plant resilience undergoing these perturbations. with other stimulants like compost, humic acid, phytohormones, microbes nanoparticles could be synergistic some situation enhance survivorship especially saline, waterlogged arid conditions. Overall, provide effective low-cost solution, nutrient-poor highly cultivation.
