The global healthcare market in the post-pandemic era emphasizes a constant pursuit of therapeutic, adaptogenic, and immune booster drugs. Medicinal plants are only natural resource to meet this by supplying an array bioactive secondary metabolites economic, greener sustainable manner. Driven thrust demand for immunity imparting nutraceutical life-saving plant-derived drugs, acreage commercial cultivation medicinal has dramatically increased recent years. Limited resources land water, low productivity, poor soil fertility coupled with climate change, biotic (bacteria, fungi, insects, viruses, nematodes) abiotic (temperature, drought, salinity, waterlogging, metal toxicity) stress necessitate plant productivity enhancement through strategies. Plants evolved intricate physiological (membrane integrity, organelle structural changes, osmotic adjustments, cell tissue survival, reclamation, root-shoot ratio, antibiosis, hypersensitivity, etc.), biochemical (phytohormones synthesis, proline, protein levels, antioxidant enzymes accumulation, ion exclusion, generation heat-shock proteins, synthesis allelochemicals. cellular (sensing signals, signaling pathways, modulating expression stress-responsive genes etc.) mechanisms combat stresses. Endophytes, colonizing different tissues, synthesize novel compounds that can harness mitigate environmental cues, thus making agroecosystems self-sufficient toward green approaches. host set endophytes another interact highly complex manner involving adaptive mechanisms, including appropriate responses triggered stimuli received from sensors situated on cytoplasm transmitting signals transcriptional machinery nucleus withstand stressful environment effectively. Signaling pathways serve as crucial nexus sensing establishing plants’ proper molecular responses. However, underlying critical endophytic microbes meager. This review comprehends diversity endophyte-mediated plant-microbe interactions tolerance understanding cascades defined Leveraging knowledge, researchers design specific microbial formulations optimize health, increase nutrient uptake, boost crop yields, support resilient, agricultural system.

Location: root architecture structures rhizosphere microbial associations

Journal of Experimental Botany, Journal Year: 2023, Volume and Issue: 75(2), P. 594 - 604

Published: Oct. 26, 2023

Abstract Root architectural phenotypes are promising targets for crop breeding, but root effects on microbial associations in agricultural fields not well understood. Architecture determines the location of within systems, which, when integrated with soil vertical gradients, functions and metabolic capability rhizosphere communities. We argue that variation architecture crops has important implications exudation, recruitment function, decomposition fate tissues exudates. Recent research shown microbiome changes along axes among classes, tips have a unique microbiome, exudates change system depending physicochemical conditions. Although fresh produced larger amounts tips, mature segments also plays role influencing gradients. more is needed to understand specific structure discuss candidate may determine hotspots systems relevance systems.

Microbiome-Mediated Strategies to Manage Major Soil-Borne Diseases of Tomato

Plants, Journal Year: 2024, Volume and Issue: 13(3), P. 364 - 364

Published: Jan. 25, 2024

The tomato (Solanum lycopersicum L.) is consumed globally as a fresh vegetable due to its high nutritional value and antioxidant properties. However, soil-borne diseases can severely limit production. These diseases, such bacterial wilt (BW), Fusarium (FW), Verticillium (VW), root-knot nematodes (RKN), significantly reduce the yield quality of tomatoes. Using agrochemicals combat these lead chemical residues, pesticide resistance, environmental pollution. Unfortunately, resistant varieties are not yet available. Therefore, we must find alternative strategies protect tomatoes from diseases. One most promising solutions harnessing microbial communities that suppress disease promote plant growth immunity. Recent omics technologies next-generation sequencing advances help us develop microbiome-based mitigate This review emphasizes importance interdisciplinary approaches understanding utilization beneficial microbiomes improve crop productivity.
