Abstract
Tropical fruits, such as bananas, passion fruit, mangoes, and lychees, are rich in vitamins, flavonoids and non-flavonoid phenols, and are the healthiest way to intake bioactive compounds in one's daily diet. Coupled with their unique taste, tropical fruits are becoming more increasingly popular. The production of bananas is second only after grapes, while other tropical fruit are limited by the planting environment, resulting in a relatively low planting area and yield. With the improvement in breeding technology and planting technology, the development of tropical fruit crops will have broad prospects. MYB plays a major regulatory role in several biological processes, including growth and development of plants, quality formation, and stress resistance. There is a comparatively junior level of research on tropical fruit crops compared to grain fruit and model plants. Despite the progress that has been made in the development of molecular biology methods that can transform the genetic makeup of tropical fruit crops, the functional understanding of the multiple MYB genes is still in its initial stages. This paper aims to review the current status of the research on the development of these genes and their prospects. It is expected to provide a reference for the study of MYB transcription factors in tropical fruit crops and to provide new ideas for the functional resolution of MYB transcription factors in different biological processes.
