Researchers from the Guangxi Academy of Sciences and the Chinese Academy of Sciences in China conducted a study to investigate soil bacterial diversity and its relationship with soil properties in healthy and stunted mango trees. Using metagenomic sequencing, they analyzed soil samples from 32 mango trees in Leye County, Baise City, China, to better understand the role of soil microbiomes in mango growth and health.
The study revealed significant differences in bacterial diversity and abundance between healthy and stunted mango soils. Joint analysis with soil physical and chemical properties showed that several bacterial taxa were strongly correlated with key soil parameters such as pH, organic matter, total nitrogen, phosphorus, and potassium. For instance, Candidate, Acidobacterium, and Pelagibius were positively correlated with pH, while Paraburkholderia and Streptosporangiales showed negative correlations.
The researchers also isolated a pathogen (M1) responsible for mango anthracnose and identified a beneficial rhizosphere bacterium, Leclercia adecarboxylata MHA-2-F1, which exhibited multiple plant-growth-promoting traits. This bacterium not only inhibited the mango anthracnose pathogen but also enhanced root development and plant wet weight.
These findings provide valuable insights into the microbial interactions affecting mango growth and disease resistance, offering pathways for sustainable agricultural practices and reduced reliance on chemical inputs.
