Interpreting the Genetic Symphony: Strigolactones and Their Regulatory Effect on Plant Growth and Development

Strigolactones (SLs) are important plant hormones that regulate multiple physiological processes and interact with the environment to control plant growth and development. They have a vital function in the synthesis of other important plant hormones, including SLs, which are necessary for the overall health and production of plants. The biosynthesis pathway of strigolactones (SLs) is essential for the regulation of plant growth and development. This mechanism involves the conversion of carotenoids into carlactone by oxidation. Furthermore, SLs play a role in controlling nutrition by stimulating the growth of cells, increasing the branching of hyphae, and triggering the germination of spores. SLs modulate root architecture and growth by interacting with other plant hormones such as auxin, CK, gibberellin, and zaxinone. Moreover, plants react to environmental signals, assisting them in effectively distributing resources and adapting their growth patterns to varying circumstances. SLs play a role as mediators in both mutually beneficial and harmful interactions within the plant kingdom. They govern the signalling of abscisic acid (ABA), the dormancy of seeds, and the responses to stress. Structural Ligands (SLs) play a crucial role in various areas of plant development and growth, such as controlling the opening and closing of stomata, increasing resistance to environmental stress, and directing the process of ageing and survival in deciduous trees. They are a significant class of growth regulators that have immense promise in controlling diverse biological processes in plants. Their many regulatory roles in distinct plant tissues are affected by a variety of physiological and genetic variables. This chapter seeks to investigate the substantial influence of several genes and genetic variables, facilitated by strigolactones, on the growth, development, and physiological activities of plants.
