Flavonoids regulate rhizosphere microbial communities and enhance salt tolerance in apples
The apple (Malus domestica) is a deciduous tree that is taxonomically classified in the genus Ap-ple in the family Rosaceae. In China, apple cultivation has a long history and has become one of the important cash crops. The fruit is favored by consumers for its unique flavor and rich nutrition, and it also occupies an important position in the agricultural economy. Salt stress is a common abiotic stress in apple planting, which seriously affects its growth and economic benefits. Therefore, it is of great significance to study the salt resistance mechanism of apple to improve its planting efficiency and adaptability.
