A key book for rhizobiologists is Janet Sprent's Nodulation in Legumes (2001) 146 pp., Royal Botanic Gardens, Kew

She has recently published a very informative Tansley review in The New Phytologist (2007) with the title: Evolving ideas of legume evolution and diversity: a taxonomic perspective on the occurrence of nodulation.
