ESTABLISHED

The world’s largest rhizobia resource bank and database

One of the two most important rhizobia classification laboratories in the world

A set of scientific classification and identification of rhizobia technical methods and data processing procedures

DISCOVERIES

Proved the diversity of the symbiosis relationship between rhizobia and legumes (one plant can coexist with a variety of rhizobia)

Revealed the biogeographical characteristics of rhizobia and related genomic differences

Revealed the difference in the effectiveness of symbiosis between close-source strains and different plant varieties (required to screen strains for crop varieties)

Discovered that rhizobia adapts to symbiotic interactions and other environmental conditions with genes unique to system branches

With C.F. Tian, Y.J. Zhou, Y.M. Zhang, Q.Q. Li, Y.Z. Zhang, D.F. Li, S. Wang et al. Comparative genome of rhizobia nodulating soybean suggests extensive recruitment of lineage-specific genes in adaptations. Proceed. Natl. Acad. Sci. 109(22):8629-34, 2012

Found that mixed planting between gramineous plants and legumes both interacting each other to achieve high yield, overcoming the nitrogen inhibition or barrier
