“…Therefore the character has not been used for the present phylogenetic analysis. Lersten (1983) reviewed the data of suspensors from ഠ180 species in 80 genera of Leguminosae. He reported uninucleate filamentous suspensors in Cicereae, Trifolieae, and Galega, and a multinucleate four-celled suspensor in Vicieae.…”

A cladistic analysis of tribes Cicereae, Trifolieae, and Vicieae was carried out using 33 morphological, anatomical, karyological, and chemotaxonomical characteristics. Transformation polarities of the character states were developed by comparison with the character states of the genus Galega, the sister group of the tribes. Cicereae and Vicieae were found to be a monophyletic group, and Trifolieae was its sister group. The seven synapomorphic characters of Cicereae and Vicieae were presumed to be: germination hypogeal vs. epigeal; first leaf in seedlings scarious vs. laminous; leaves paripinnately and tendrilous vs. imparipinnately and etendrilous; postchalazal vascular bundle present in seed coats vs. absent; a cotyledon flap present at antihilar side vs. absent; radicles short in seeds vs. long; and plumules long in seeds vs. short.

Abstract. Seed storage proteins are thought to be accumulated exclusively in the cell-expansion phase of embryogenesis and metabolized during germination and seedling growth. Here we show by a sensitive immunohistological technique that the two Vicia faba L. storage proteins vicilin and legumin are accumulated in substantial amounts in the suspensor and coenocytic endosperm and to a lesser extent in the mid-globular embryo. Both proteins appear and disappear at precise stages specific for each tissue. In the endosperm the accumulation starts around 12 d after pollination (DAP). After a maximum attained at 14-15 DAP, storage proteins are degraded within about 4 d. Accumulation is restricted to that part of the endosperm which covers the embryo and displays the highest levels of endoploidy (maximum 96n). In all other parts of the endosperm, storage proteins do not appear to accumulate, although storage-protein-specific mRNA synthesis takes place. In the suspensor, storage proteins are already observed at 6 DAP and disappear very quickly at approximately 10 DAP. Low amounts of legumin and vicilin are also detectable in the mid-globular embryo, but disappear completely as the embryo enters the heart stage. We conclude that storage proteins of Viciafaba accumulated transiently during early seed development are used as nutritive reserves for the growing embryo.
