Geographic origin and nodulation ability of the Burkholderia isolates associated with indigenous species in the tribes Podalyrieae and Hypocalypteae.

aThe legume hosts are listed with abbreviated genus names, i.e., H. = Hypocalyptus; V. = Virgilia; P. = Podalyria; C. = Cyclopia.bThe name of the isolates are in bold while the letters in brackets indicate the host plants on which nodulation tests were successful. S = siratro (Macroptilium atropurpureum; Tribe Phaseoleae), C = cowpea (Vigna unguiculata; Tribe Phaseoleae), HC = Hypocalyptus coluteoides. No brackets indicate nodulation not confirmed, except for the Cyclopia isolates which are indicated as authenticated in Dr. Kock’s thesis [41].cIsolated by author using glasshouse trapping techniques.*These isolates were originally isolated from trapping experiments and not directly from nodules in the field.
