What is it about?

Micromonospora is a Gram-positive actinomycete that has plant-growth-promoting activities. We sequenced its genome to learn more about the mechanisms it employs for stimulating plant growth. We found a number of gene candidates for biocontrol activities such as chitinase activity, but found no evidence for nitrogen fixation ability.

Why is it important?

Our findings show that this filamentous bacterium, originally isolated from the interior of nitrogen-fixing nodules of Casuarina growing in Mexico. Although it does not fix nitrogen, it exhibits numerous other traits that could be involved in helping plants grow in adverse environments.


Although L5 is not an easy bacterial species to work with, it offers much promise as a PGPR, especially in combination with nitrogen fixing bacteria.
