Variations in rhizosphere microbial community structure and function among diploid, triploid, and tetraploid watermelon cultivars
The rhizosphere microbiome, as the “second genome” of plants, plays a crucial role in nutrient acquisition, stress resistance, and soil health maintenance. Polyploidization is a key breeding strategy for watermelon: triploids are valued for seedlessness and high stress resistance, while tetraploids serve as important p...
