While promiscuity amongst people is commonly scorned, symbiotic promiscuity could be a signal of fantastic teamwork in different species. Plant progress, particularly in legumes, prospers by means of mutualistic interactions with soil micro organism, generally referred to as rhizobia. A profitable interplay culminates with the formation of a root nodule, the place rhizobia present nitrogen to the plant. This affiliation depends upon complicated chemical dialogs, which limit plant-bacterial compatibility. However, distinctive instances of symbiotic promiscuity might happen, and sure legumes can develop nitrogen-fixing nodules with numerous rhizobia.
A latest research printed in Molecular Plant-Microbe Interactions by Mohammad Zarrabian of Aarhus University and colleagues found one such case with the legume Lotus burttii. While the carefully associated species Lotus japonicus developed nodules with solely two strains, the researchers revealed that L. burttii can kind nodules—correctly colonized by micro organism—with as much as 30 completely different rhizobial strains because of a single area, or locus, within the L. burttii genome.
This extraordinary symbiotic promiscuity whatever the rhizobial pressure signifies that the locus comprises useful details about genetic components in legume-rhizobia symbiosis. In this context, research have primarily centered on the bacterial perspective, however analyzing the plant perspective unveiled a key genetic area for rhizobial compatibility in L….
