Abstract Salinity and drought stress substantially decrease crop yield superiority, directly threatening the food supply needed to meet rising needs of growing total population. Nanotechnology is a step towards improving agricultural output tolerance by efficacy inputs in agriculture via targeted delivery, controlled release, enhanced solubility adhesion while also reducing significant damage. The direct application nanoparticles (NPs)/nanomaterials can boost performance effectiveness physio‐biochemical molecular mechanisms plants under conditions, leading advanced tolerance. Therefore, we presented effects plant responses explored potential nanomaterials for systems, discussed advantages applying NPs at various developmental stages alleviate negative salinity stress. Moreover, feature recent innovations state‐of‐the‐art nanobiotechnology, specifically NP‐mediated genome editing CRISPR/Cas system, develop stress‐smart crops. However, further investigations are unravel role nanobiotechnology addressing climate change challenges modern systems. We propose that combining speed breeding techniques could enable designing climate‐smart cultivars (particularly bred or genetically modified varieties) security world

Saline stress is one of the most critical abiotic factors that can lessen crops' productivity. However, emerging nanotechnology, nano-fertilizers, and developing knowledge phytochromes potentially mitigate negative effects saline on seed germination. Therefore, aim this study was to investigate priming either with zinc oxide nanoparticles (ZnO-NPs; 50 100 mg L-1) or 24-epibrassinolide (EBL; 0.2 0.4 μM) their combinations maize (Zea mays L.) grains sown in salt-stressed soil (50 mM NaCl). treatments significantly affected all germination traits chemical analysis seeds as well α-amylase activity. Compared un-primed seeds, ZnO-NPs EBL increased cumulative percentage, energy, imbibition rate, increase grain weight, K+ content, activity, reduced time, days 50% emergence, Na+ uptake, Na+/K+ ratio salt-stressed-soil The combination L-1 + μM resulted highest improvements for studied comparison other individual combined treatments.

Published: Dec. 24, 2021

Exposure of crops to stress is the most significant barrier agricultural output and food security worldwide. Stress induces changes in plants' physiological functions, which leads lower plant growth yield. Plants undergo a variety molecular, cellular, combat various abiotic stresses. suffer from increased osmotic pressure outside root due stresses like drought or salt that ultimately result reduced water availability roots. In addition morphological modifications, such as leaf potential, accumulation osmoprotectants, antioxidant activities, so on occur response Seed priming novel yet simple technique involves use beneficial eco-friendly biological agents improve functioning seeds. This also plays vital role restoring agro-ecological balances through improvement soil fertility by decreasing contamination. An understanding mechanisms involved seed bio-priming with growth-promoting microbes very crucial efficiently utilise this towards sustainability. It generally thought advancement metabolic processes along activation repairing systems during pre-germination stage are central reasons behind promotion acquired tolerance. The application rhizobacteria agriculture has been emerging resilience.

Food security has become the most challenging task in current scenario of population growth and future perspective everchanging environment. Cultivation management plants is now a major challenge for modern food production, which further compounded by lack common background among many disease control disciplines. All crop simultaneously engage with billions microbes from their surroundings, are harmless rather beneficial to plant as they promote provide protection opposition diseases. However, few species-specific adapted cause diseases devastating effects on yields. To prevent pathogen infection, have evolved an innate immune system that recognises conserved cell surface molecules species possess. Activation ceases non-adapted invasion, but this comes fitness cost significantly reduces leads yield penalty. Apart systems controlling pre-programmed defence reactions, can also increase responsiveness response selected environmental signals. This phenomenon known "defence priming". The costs priming lower than those constitutively activated defences, suggesting functions ecological adaptation respond faster hostile Although rarely provides full protection, its broad spectrum effectiveness, long-lasting durability, inheritance generations make it attractive integrated management.
