- Mutualism is an interaction in which two organisms benefit from each other.
- The symbiotic relationship between the bacterium Sinorhizobium meliloti and the plant Medicago truncatula is dictated by the bacterial plasmids.
- The Heath lab has a collection of 191 Sinorhizobium meliloti strains with different symbiotic plasmids that vary across populations (Riley et al., 2022).
- Each strain can be a better or worse partner for its plant host in symbiosis with the variation in fitness being called partner quality (Fig. 1)
- These traits can be traced back to the genetic elements that underlie this effect (Batstone et al.,
- These genetic elements can be found in gene clusters that are gained or loss across strains (Fig. 1; Riaz, Sosa Marquez, in prep.).
We need assurances of these important and variable clusters presence to understand their mechanism of gene movement
