TL;DR: It is concluded that colony colour, serological and symbiotic properties are sufficiently stable to be of use in long-term ecological studies although antibiotic sensitivity appears less stable.
Abstract: Rhizobia suited to Lotononis bainesii do not occur naturally in Australia. Two serologically distinct strains of African origin were introduced into an isolated field station where perennial Lotononis-pangola grass pastures are grazed. Paddocks varied in the period of rhizobial occupancy from 5–12 years. Stability of four rhizobial characters: colony colour, effectiveness, cell antigens and antibiotic sensitivity were assessed from nodules on persisting Lotononis. Both strains became established throughout the 782 ha. No changes were observed in colony colour or serological reaction. Symbiotically, 8.5% of isolates had a lower N fixing capacity than stock cultures held in the laboratory although there were no ineffective isolates. Change in effectiveness was unrelated to serotype or to time of occupancy. There was also little change in antibiotic sensitivity although one isolate was tolerant to 15 parts/106 streptomycin. The red bacterium Protaminobacter rubra was recorded for the first time as a cohabitant of Lotononis nodules. It is concluded that colony colour, serological and symbiotic properties are sufficiently stable to be of use in long-term ecological studies although antibiotic sensitivity appears less stable.

TL;DR: Two specificity groups occur within Lotononis s.l.: Listia species are symbiotically specific, while species of Leobordea and Lotononi s.s.l. are generally promiscuous and interact with rhizobia of diverse chromosomal and symbiotic lineages.

TL;DR: Of the species studied, Lupinus polyphyllus was the only one capable of reasonable growth where no P was added to the soil and its greater seed reserves appeared to contribute substantially to its greater growth and P uptake under conditions of low P input.
Abstract: The phosphate response patterns of tropical and temperate legumes were compared in a glasshouse trial on a high country yellow-brown earth subsoil Differences in growth and P response patterns could be explained by the known differences in tolerance of Al toxicity The temperate legumes Lotus pedunculatus and Lupinus polyphyllus appeared to be able to tolerate Al toxicity as well as the torpicallegume Lotononis bainsu and more so than Trifolium semipilosum However Trifolium repens was less tolerant than T semipilosum Of the species studied, Lupinus polyphyllus was the only one capable of reasonable growth where no P was added to the soil The greater seed reserves of Lupinus appeared to contribute substantially to its greater growth and P uptake under conditions of low P input

TL;DR: The phylogenetic and taxonomic significance of morphological and anatomical trends in fruits of tribe Crotalarieae has been evaluated, with emphasis on the genus Crotalaria and its seemingly distinctive, inflated and balloon-shaped pods.

TL;DR: A general survey of alkaloids in the tribe Crotalarieae showed that useful chemotaxonomic data may be obtained, and the major alkaloid types seem to be characteristic for each of these genera.
