Plant Auxin Responsive Gene SAUR: A Review
Auxin is an important regulatory factor in the process of plant growth and development, and plants achieve their own growth and development through the regulation of auxin. As a member of the early auxin response gene family, the SAUR gene family is one of the indispensable regulatory factors in the auxin signal transduction pathway. In order to study the role of SAUR genes in biological processes such as plant growth and development and stress response, the bioinformatics characteristics, expression patterns, and regulatory mechanisms of the SAUR gene family were analyzed. The functions of SAUR genes in plant cell elongation growth, light-mediated cotyledon and apical hook opening, flower organ formation, fruit development, and stress response were summarized. It was pointed out that SAUR genes not only affected plant growth and development in multiple aspects, but also participated in the response of plants to abiotic stress. This study provides a theoretical basis for future research on the molecular mechanisms of SAUR genes and the cultivation of plant varieties.
