This review delves into the role of plant growth-promoting microbes (PGPMs) in sustainable agriculture by enhancing soil health, improving stress tolerance, and controlling diseases. PGPMs, which include bacteria, fungi, other microorganisms, are increasingly recognized as important contributors to promoting eco-friendly agricultural practices. Their ability improve nutrient availability, stimulate growth, protect crops from environmental stressors makes them a cornerstone for resilient efficient farming systems. By reducing dependency on synthetic fertilizers pesticides, PGPMs play vital preserving resources, minimizing greenhouse gas (GHG) emissions, combating climate change’s negative impacts. article thoroughly explores complex interactions between nutrients, pathogens, abiotic stressors. It also examines how these influence phytohormone production signaling pathways, ultimately impacting crop growth development. Furthermore, this discusses enhance uptake, modulate immune responses, resilience, offering holistic understanding their multifaceted contributions farming. synthesizing current research highlighting future directions, underscores potential revolutionize activities, ensuring food security sustainability face global challenges.

Abstract Food safety and security are now among the most urgent problems to be resolved as world’s population continues grow. Intensive agriculture is required meet demands of a growing guarantee greater agricultural yield. Chemical pesticides fertilizers an essential part intensive farming. Their extensive use accelerates depletion other important minor nutrients, resulting in poor soil fertility nutritional imbalance. There serious health environmental hazards associated with several these hazardous chemicals. In context, for first time, this study represents innovative experiment exploring impact exogenously applied k-carrageenan on plant growth, physiological parameters, phytochemical content, macronutrients, oil percentage Ocimum basilicum plants. The investigation assessed effect varying levels; 0.30, 0.60, 0.90, 1.20 mM versus untreated control. findings revealed that all treatments significantly enhanced growth indicators compared analysis demonstrated foliar application k-carrageenan, particularly at mM, total chlorophyll, chlorophyll a, b, carbohydrate O. oils show rich, nuanced flavors higher levels Methyl cinnamate, Camphor, trans-methyl Eucalyptol, Linalool, β-Caryophyllene treatments. Treatment effects were also observed macroelements content Nitrogen (N), phosphorus (P), potassium (K). k-carrageenan-induced alterations noted contents compounds. These results suggest can growth-promoting agent enhance yield,

Abstract Salinization, as a serious climate change phenomenon, continues to cause critical issues for soils and crops. Abundance of genetic diversity plants could contribute in solving the impacts salinity. However, relations between physiological molecular traits plant species need deep investigation interpretation. Pot experiments were conducted greenhouse investigate difference behavior two amaranth when they beforehand subjected salinity-stress conditions, specifically on some specific characteristics. After 45 days from transplanting, salt stress was induced using 150 mM sodium chloride solution. Treatments arranged randomized complete block design three replications. 0, 2, 6, 10, 24 h, samples collected evaluate data well gene expression. The immediately frozen liquid nitrogen stored -80⁰ C ultralow temperature refrigerators. Findings revealed that red ( Amaranthus cruentus ) more tolerant saline than green hypochondriacus ). Result malondialdehyde (MDA) content increased after 2 h then decreased (after 6 10 h) before rising again h. In amaranth, MDA initially increasing later decreasing zigzag pattern ending an increase There initial steep rise proline which continued still moderately till it stopped. Results also showed gave higher value superoxide dismutase (SOD) activity compared with all tested salinity exposure times. expression four genes assessed through quantitative PCR indicated efficiency SOS1, HKT1, NHX1, DGR2 genes, encode adaptation-related proteins under stress. summary, current work demonstrated be efficient resource improving salt-tolerant genotypes belonging genus.
