The Long Laboratory studies the early stages of symbiosis between Rhizobium (also Sinorhizobium) meliloti and and its host plants in the genus Medicago. The symbiosis is uniquely approachable by experiment because each partner can be genetically manipulated, and transgenic organs can be constructed, allowing highly specific genetic tests of various components of signal and response. The lab uses genetics, biochemistry and cell biological approaches to study how cell division, growth, and gene expression arise in each partner due to stimulation from the other.
