Advances in sequencing and key character analysis of mango (Mangifera indica L.)

Mango (Mangifera indica L.) is an important fruit crop in tropical and subtropical countries associated with many agronomic and horticultural problems, such as susceptibility to pathogens, including powdery mildew and anthracnose, poor yield and quality, and short shelf life. Conventional breeding techniques exhibit significant limitations in improving mango quality due to the characteristics of long ripening, self-incompatibility, and high genetic heterozygosity. In recent years, much emphasis has been placed on identification of key genes controlling a certain trait through genomic association analysis and directly breeding new varieties through transgene or genotype selection of offspring. This paper reviews the latest research progress on the genome and transcriptome sequencing of mango fruit. The rapid development of genome sequencing and bioinformatics provides effective strategies for identifying, labeling, cloning, and manipulating many genes related to economically important traits. Preliminary verification of the functions of mango genes has been conducted, including genes related to flowering regulation, fruit development, and polyphenol biosynthesis. Importantly, modern biotechnology can refine existing mango varieties to meet the market demand with high economic benefits.

Automated summary

Mango is an important fruit crop in tropical and subtropical countries, but it faces agronomic and horticultural problems such as susceptibility to pathogens, poor yield and quality, and short shelf life. Conventional breeding techniques have limitations in improving mango quality due to its long ripening process, self-incompatibility, and high genetic heterozygosity. Recent research has focused on identifying key genes through genomic association analysis and using biotechnology to breed new varieties. This paper reviews the progress in genome and transcriptome sequencing of mango fruit, which has provided effective strategies for manipulating genes related to economically important traits and refining existing varieties.
