Nanotechnology and biological advances, novel tools for plant genetics and physiological role of newly crops and limited factors affecting growth

Nano-pesticides are essential for the successful and sustainable management of different pests, and they can decrease the use of agrochemicals, thereby mitigating current environmental dangers. Nevertheless, advancements in nano-particles or micro-particles, as well as distribution models for biolistic gene delivery in various plants, are still needed to enhance grain growth and crop and plant protection. , seed priming is being used effectively to expedite and synchronize germination, increase seedling vigor, and make plants extra resilient to various biotic and abiotic stresses, resulting in increased efficiency and quality of food. Nano fertilizers have distinct properties like mega absorption, increase in production, enhanced activity of photosynthesis, and a substantial improvement in leaf surface area. Growth of plants is changed to a particular environment conditions at different phases of development; and hence, a proper choice of planting date increases photosynthesis efficacy. In this perspective, providing carbon nano-tubes in to the chloroplasts has resulted in a progress for plants' enhanced capacity to collect more energy from the sun. Lower rates of photosynthetic activity in the crop plants under the cold stress limited metabolic pathways for Carbon assimilation.
