DENARIE (New Reader) is studying the Nodulation (Nod) factors that are synthesized by Rhizobium, Bradyrhizobium, Azorhizobium, and Sinorhizobium. Nod factors are lipo-chitooligosaccharide signals that are involved in the specific recognition of the legume host and the induction of nodules. While studying the structure of Nod factors, they have discovered that their structure is related to the taxonomy of the host legume, not to the bacterium. For example, the various rhizobia that nodulate tribes Cicereae, Galegeae, Trifolieae, and Vicieae produce Nod factors which are acylated by specific poly-unsaturated fatty acids. Similar Nod factors are not produced by rhizobia that nodulate legumes which are not derived from putative galegoid ancestors. They want to contact taxonomists who might be interested in exchanging ideas concerning the possibility of using Nod-factor structure to clarify legume taxonomy, especially relationships between the Loteae and the galegoid complex.

All sizes of buds, from youngest tight inflorescences, are needed in the collection, as well as a few open flowers. She offers reprints and can make collections of some native California legumes and introduced Mediterranean, tropical, or subtropical legumes.
