Zinc is one of the important micronutrients required for optimal plant growth. You can consider it as a potential alternative for zinc supplementary that can convert inorganic zinc into organic available forms. A plays numerous functions for plants during the life cycle of plant growth.
By colonizing the rhizosphere and solubilizing complex zinc compounds into simpler ones, zinc solubilizing bacteria improve plant growth and development increment of crop yield. The use of effective zinc solubilizing bacteria is the first and most important step in overcoming and fulfilling the requirement of essential minerals for plants. It is a powerful antioxidant
The effect of the plant was studied using growth parameters and atomic absorption spectroscopy to determine the zinc content of the shoot, root, and grains. Zinc factors affect the normal development of fertilization, fruiting, floral tissues, and flowering. Due to the deficiency of zinc in the plant, can lead to chlorosis, retarded shoot growth, reduce leaf size, light and fungal infections, and also affects grain yield.
Plant growth promoting rhizobacteria promote plant growth by solubilizing nutrients and assisting in nutrient acquisition, or by releasing python hormones or biocontrol agents to protect the plant from various pathogens. Several PGPR is effective zinc solubilizers. By colonizing the rhizosphere and solubilizing complex zinc compounds into simple ones, these bacteria improve plant growth and development by making zinc available to the plants.
With the help of acidification, zinc solubilizing microorganisms solubilize zinc. The microbes that are produced with organic acids in soil sequester the zinc captions and decrease the PH of the nearby soul space and enhance zinc solubility. Organic residues, such as cow dung, are supplemented with microorganism inoculants to enrich the soil profile and improve its texture. This also promotes necessary plant growth and soil health.
The deficiency of zinc in the soil can be one of the very common micronutrient deficiencies that can result in decreased crop production. Different methodologies are being formulated by plant scientists to tackle the zinc deficiencies in crops through fertilizer application or using plant breeding strategies that help to augment the absorption or bioavailability of zinc in grain crops. They play a key role in carrying out the bioavailability of soil phosphorus, zinc, iron, and silicate to plant roots.
It is necessary to have a good understanding of microbial interaction that significantly raises the success rate of field application when viable applications of PGPR are being tested. The deficiency of zinc in soil hampers the growth of plants such as rice, wheat, sugarcane, and corn.
Zinc solubilizing bacteria strains have been shown to increase the zinc content of straw and grains in soybeans and wheat, as well as to improve food efficacy and mimic zinc deficiency.
One of the most important micronutrients, zinc, is required in trace amounts for the proper growth and development of living organisms. Zn-finger transcription factors are essential for normal floral tissue development, fertilization, fruiting, and flowering. When zinc is deficient in wheat, it leads to the yellowing of leaves and stunted growth.
Zinc solubilizing bacteria by PGPR is a new approach and requires more testing of the most strain for this activity. The usage of zinc solubilizing for the growth of the plant may not be very cost-effective and increase crop growth.
