''M. atropurpureum'' can be nodulated by a range of alpha-rhizobial strains, which allow for nitrogen-fixation and allowing the plants to thrive in nutrient poor soils. Soil, pH, phosphate, and CaCO3 content and granulation influence the type of rhizobial nodulation that occurs.

Taxonomic notes
Description
A perennial species in tropical regions and an annual in subtropical climates. It is a trailing, climbing, twining species with a deep, swollen taproot (Morris 2010).
Distribution
It is a native to tropical continental America, and is distributed through out the tropics [1].
Ecology
Habitat
Habitats include disturbed ruderal areas such as lawns, along railroad beds, and pastures (FSU Herbarium). It has great economic importance in cover crop, forage and prevents soil erosion (Cook et al. 2005). A long, deep taproot adn the ability to reduce evapotranspiration by shedding its leaves allows for toleration of dry conditions[2].
M. atropurpureum can be nodulated by a range of alpha-rhizobial strains, which allow for nitrogen-fixation and allowing the plants to thrive in nutrient poor soils. Soil, pH, phosphate, and CaCO3 content and granulation influence the type of rhizobial nodulation that occurs. When M. atropurpureum grows under dry, high temperature conditions, Burkholderia tuberum induced nitrogen fixing nodules (Angus et al. 2013).
