“…Gums are a group of polysaccharides that are produced naturally by certain botanical (trees and shrubs, seeds, and tubers), algal (red and brown seaweeds), or microbial sources (Amara, 2022). Some trees and shrubs excrete gums as sticky secretions in response to mechanical injuries or biological attacks that usually harden to seal the wound in order to give protection (Nussinovitch, 2009).…”

Natural polymers have many uses, and Tragacanth gum is just one of them. Many people are interested in natural gums because of their many attractive characteristics, such as being ‘green’ bio-based renewable materials, being easily accessible, inexpensive, and structurally diverse. One class of naturally occurring polysaccharides is called gum because of its tendency to create a gel or a thick solution. Among the many plant-based raw materials, these polysaccharide gums are abundant. Hydrogels, which are three-dimensional polymeric webs that can imitate live tissues, have demonstrated remarkable potential as adjustable biomaterials in numerous regenerative techniques due to their high water or biological exudate absorption capacities. Natural polysaccharides, often known as gums, are present in many different types of trees and possess many desirable properties, such as being renewable, biocompatible, biodegradable, non-toxic, and amenable to chemical modification. Many people are curious about certain parts of the food, water, energy, biotech, environmental, and healthcare sectors as of now. Gum, a type of very important and unique food ingredient, has many vital uses in the food business. Cosmetics, coating, photosensitive resin, fertilizer, casting, pharmaceuticals, and tobacco are just a few of the non-food businesses that make use of their strong water-affinity and structural plasticity. There are a lot of benefits to hydrogels made from natural gums as opposed to those made from synthetic sources. Synthesis hydrogel polymers have been the center of interest among these non-food applications because of their extensive use in the pharmaceutical and medical fields. The Tragacanth gum hydrogels used for medication delivery and tissue engineering have been the focus of this study. We also paid close attention to drug delivery, physical-chemical properties, and the extraction of Tragacanth gum. Our research has a wide range of biomedical applications, including tissue engineering for bone, skin, fixation of bone, periodontal, and cartilage. Possible futures based on hydrogels made of Tragacanth gum were likewise our primary focus.

“…The induction of microbial communities inhabiting the rhizosphere by plant roots has been brought to notice. The potential of microbial communities is a significant factor, contributing to the solubility of metals and as immobilizers of soil metals as a result of hydrated ferric oxides and the precipitation of sulfides or complex sugar (polysaccharides) exudation [ 121 ]. On the surface of fungal cell walls, the functional groups perform a significant task in the adsorption of metals from the soil [ 122 ].…”

The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability of the plants, are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They are biotic inducers that provide benefits and carry out important functions in agricultural sustainability. The problem encountered in the agricultural system nowadays is how to meet population demand based on crop yield and protection without putting the environment and human and animal health at risk based on crop production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature to ameliorate the production of crops by improving the growth of the shoots and roots of crop plants, the germination of seeds, the production of chlorophyll for photosynthesis, and the abundant production of crops. PGPF’s potential mode of action is as follows: the mineralization of the major and minor elements required to support plants’ growth and productivity. In addition, PGPF produce phytohormones, induced resistance, and defense-related enzymes to inhibit or eradicate the invasion of pathogenic microbes, in other words, to help the plants while encountering stress. This review portrays the potential of PGPF as an effective bioagent to facilitate and promote crop production, plant growth, resistance to disease invasion, and various abiotic stresses.
