Abstract

The emergence of biodiversity in rhizobia after the introduction of exotic legumes and their respective rhizobia to new is a challenge for contemporary rhizobiology. Biserrula pelecinus L. is a pasture legume species that was introduced to Australia from the Mediterranean basm and which is having a substantial impact on agricultural productivity on acidic and sandy soils of Western Australia and New South Wales (Howieson et al., 2000). This deep-rooted plant is also valuable in reducing the development of dryland salinity This legume is nodulated by a specific group of root-nodule bacteria that belongs to Mesorhizobium (Nandasena et at , 2001, 2007).
