Natural rubber has flexibility and strength, as well as impurities and vulnerability to environmental conditions and hydrocarbons. Additionally, it has a lot of tensile strength and adheres easily to other materials.
Taraxacum koksaghyz has been identified as one of the most promising alternative rubber crops. Its high-quality rubber is produced in the latex of laticifers, a specialized cell type that is organized in a network of elongated tubules throughout the entire plant body. In order to gain insights into the physiological role s of latex and hence laticifer biology, we examine the effects of barnase-induced latex RNA degradation on the metabolite and protein compositions in the roots. We established high-quality datasets that enabled precise discrimination between cellular and physiological processes in laticifers and non-laticifer cell types of roots at different vegetative stages. We identified numerous latex-specific proteins, including a perilipin-like protein that has not been studied in plants yet. The barnase-expressing plants revealed a phenotype that did not exude latex, which may provide a valuable genetic basis for future studies of plant—environment interactions concerning latex and also help to clarify the evolution and arbitrary distribution of latex throughout the plant kingdom.
Latex is a stable dispersion emulsion of polymer microparticles in an aqueous medium. It is found in nature, but synthetic latexes can be made by polymerizing a monomer such as styrene that has been emulsified with surfactants. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants.
Rubber has been in use for thousands of years in its natural form. Most types of modern rubber are synthetic, created from different polymers manufactured from petroleum byproducts. This article looks at the different types of rubber, both natural and synthetic. A tap is inserted into the tree, and liquid latex drains into collection containers.
