Plant diseases are still the main problem for reduction in crop yield and a threat to global food security. Additionally, excessive usage of chemical inputs such as pesticides fungicides control plant have created another serious human environmental health. In view this, application growth-promoting rhizobacteria (PGPR) controlling disease incidences has been identified an eco-friendly approach coping with security issue. this review, we different ways by which PGPRs capable reducing phytopathogenic infestations enhancing yield. PGPR suppresses diseases, both directly indirectly, mediated microbial metabolites signaling components. Microbial synthesized anti-pathogenic siderophores, antibiotics, lytic enzymes, hydrogen cyanide, several others act on phytopathogens. The indirect mechanisms infestation caused stimulation immune responses known initiation systemic resistance (ISR) is triggering elicited through pathogen-associated molecular patterns (PAMPs). ISR triggered infected region leads development acquired (SAR) throughout making resistant wide range pathogens. A number including Pseudomonas Bacillus genera proven their ability stimulate ISR. However, there some challenges large-scale acceptance pest management. Further, discuss newly formulated inoculants possessing activities suppression holistic sustaining health productivity.

Enabling sustainable crop protection with induced resistance in plants

Frontiers in Science, Journal Year: 2024, Volume and Issue: 2

Published: Oct. 15, 2024

Induced resistance (IR), which enables plants to increase their resilience against insect pests and microbial pathogens by promoting own immunity, has been recognized for its value in crop protection schemes. Despite promising applications, the use of IR remained marginal compared with pesticides single genes. This review aims shed light on this disparity examining scientific milestones achieved over past decades both internal (immunological) external (ecological) strategies. The multifaceted advantages IR, particularly ability provide broad-spectrum enhance nutritional nutraceutical certain crops, are also discussed. various obstacles hindering widespread adoption strategies then revealed. After considering recent discoveries insights, potential solutions proposed, including leveraging epigenetic approaches understand mechanisms involved IR. By acknowledging that future sustainability is irreconcilable single-use technologies, proposes taking advantage latest insights regarding adaptive nature plant immune system ecological interactions safely integrate into existing emphasizing need comprehensive holistic basic translational research, sets stage alongside other foster a resilient, environmentally friendly, economically viable future, thereby ensuring health crops.

Heat Stress and Plant–Biotic Interactions: Advances and Perspectives

Plants, Journal Year: 2024, Volume and Issue: 13(15), P. 2022 - 2022

Published: July 23, 2024

Climate change presents numerous challenges for agriculture, including frequent events of plant abiotic stresses such as elevated temperatures that lead to heat stress (HS). As the primary driving factor climate change, HS threatens global food security and biodiversity. In recent years, have negatively impacted physiology, reducing plant's ability maintain disease resistance resulting in lower crop yields. Plants must adapt their priorities toward defense mechanisms tolerate challenging environments. Furthermore, selective breeding long-term domestication higher yields made varieties vulnerable multiple stressors, making them more susceptible events. Studies on predict concurrent biotic will become severe future, potentially occurring simultaneously or sequentially. While most studies focused singular effects systems examine how plants respond specific stresses, simultaneous occurrence pose a growing threat agricultural productivity. Few explored interactions between plant-biotic interactions. Here, we aim shed light physiological molecular (bacteria, fungi, oomycetes, nematodes, insect pests, pollinators, weedy species, parasitic plants), well combined impact growth We also advances designing developing various strategies address multi-stress scenarios related factors.

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.

Abstract Salicylic acid (SA) is an important phytohormone, well‐known for its regulatory role in shaping plant immune responses. In recent years, significant progress has been made unravelling the molecular mechanisms underlying SA biosynthesis, perception, and downstream signalling cascades. Through concerted efforts employing genetic, biochemical, omics approaches, our understanding of SA‐mediated defence responses undergone remarkable expansion. general, following biosynthesis through Avr effectors pathogens, newly synthesized undergoes various biochemical changes to achieve active/inactive forms (e.g. methyl salicylate). The activated subsequently triggers pathways associated with perception pathogen‐derived signals, expression genes, induction systemic acquired resistance (SAR) tailor intricate networks that coordinate Nonetheless, mechanistic regulation currently limited because crosstalk other networks, which makes this hormone more challenging.
