Recently, tree molecular breeding team from (Professor Zhang Deqiang/Professor Xie Jianbo; the College of Biological Sciences and Technology) and Francis Martin team from the University of Lorraine in France published their recent study entitled "Multifeature analysis of age-related microbiome structures reveals defense mechanisms of Populus tomentosa trees" in the top international journal "New Phytologist" (Q1, Impact factor:10.323). The study provides key information about long-lived species and their ecosystem impacts through the investigation of the defense strategy of perennials.
The research results indicated that Actinobacteria were increasingly enriched in the root endosphere over the course of poplar development and the abundant Actinobacteria could affect the phenotype of their host in return. It was further demonstrated that a single poplar gene significantly impacted the rhizosphere microbiome and the expression of a flavonoid metabolite gene significantly altered the microbial community on the roots of transgenic poplar trees.
