“…Evidence for such shoot control comes also from recent experiments on decapitated lupin seedlings by Giovannetti et al (personal communication (Trinick, 1977;Ocampo et al, 1980;Plenchette & Trouvelot, 1986). Under these conditions non-host roots still, however, show resistance to VA mycorrhizal fungi in that abortive entry points are frequent and, where roots become colonized, only intercellular hyphae form and arbuscules do not develop.…”

SUMMARYStem grafts were carried out between different varieties of vesicular-arbuscular (VA) mycorrhizal host (pea, soybean) and non-host (lupin) legumes. Only grafts on host rootstock were successful. Self-grafts of three pea varieties (Amino, Solara, Frisson), and interspecific grafts between soyhean (var. Amsoy 71) and pea (var. Frisson), did not generally affect development of, or arbuscule formation hy, Glomus intraradices Schenck & Smith or G. mosseae Nicol. & Gerd. within the rootstock. In contrast, lupin (var. Alban and Lucky) scions greatly reduced colonization of the root cortex and completely inhibited arhuscule formation hy both fungi in grafted pea rootstock. The possible role of mobile shoot factors in non-host resistance to VA mycorrhizal fungi in lupins is discussed.

“…Since lupins represent the only known legume genus which does not form VA mycorrhizas (Trinick, 1977;Harley & Smith, 1983;Avio, Sbrana & Giovannetti, 1990), we have studied the effect of stem grafts between different host (pea, soybean) and non-host (lupin) legume species on the development of VA mycorrhiza.…”

“…Most legumes growing in soil have vesiculararbuscular mycorrhiza, some (especially subfamily Caesalpinioideae) are ectomycorrhizal, and a few lack mycorrhiza (Peyronel, 1923(Peyronel, , 1924Jones, 1924;Asai, 1944;Trinick, 1977;Alexander & Hogberg, 1986;Currah & Van Dyk, 1986;Lesica & Antibus, 1986;Newman & Reddell, 1987). VA mycorrhizas increase the growth and survival of many legumes (Asai, 1944;Crush, 1974;Daft & El Giahmi, 1976), usually by enhancing P availability.…”

SUMMARYRoots of ten species of Lupinus and three other legumes collected from field soils were cleared, stained, and examined for fungal colonization. Three species were not colonized. Nine species were colonized by aseptate hyphae and vesicles attributable to vesicular-arbuscular mycorrhizal fungi. Seven species were sometimes colonized by fungi with septate hyphae, which often formed intracellular sclerotia. The associations observed are compared with previous reports and discussed in relation to legume systematics.

“…At one stage, a plant's capacity to produce root clusters was considered an alternative to the mycorrhizal habit. For example, proteacean (Purnell 1960), cyperacean (Powell 1975) and Lupinus (Trinick 1977) species are non-mycorrhizal (or weakly at most, Shane and Lambers 2005a). However, it has since been discovered that there are also many species that can produce both root clusters and mycorrhizas (reviewed in Lambers et al 2006).…”

Abstract. Soils in the south-west of Western Australia and South Africa are among the most phosphorusimpoverished in the world, and at the same time both of these regions are Global Biodiversity Hotspots. This unique combination offers an excellent opportunity to study root adaptations that are significant in phosphorus (P) acquisition. A large proportion of species from these P-poor environments cannot produce an association with mycorrhizal fungi, but, instead, produce 'root clusters'. In Western Australia, rootcluster-bearing Proteaceae occur on the most P-impoverished soils, whereas the mycorrhizal Myrtaceae tend to inhabit the less P-impoverished soils in this region. Root clusters are an adaptation both in structure and in functioning; characterized by high densities of short lateral roots that release large amounts of exudates, in particular carboxylates (anions of di-and tri-carboxylic acids). The functioning of root clusters in Proteaceae ('proteoid' roots) and Fabaceae ('cluster' roots) has received considerable attention, but that of 'dauciform' root clusters developed by species in Cyperaceae has barely been explored. Research on the physiology of 'capillaroid' root clusters formed by species in Restionaceae has yet to be published. Root-cluster initiation and growth in species of the Cyperaceae, Fabaceae and Proteaceae are systemically stimulated when plants are grown at a very low P supply, and are suppressed as leaf P concentrations increase. Root clusters in Proteaceae, Fabaceae and Cyperaceae are short-lived structures, which release large amounts of carboxylates, briefly, at a particular stage of root development. The rates of carboxylate release are considerably faster than reported for non-specialized roots of a wide range of species. Root clusters play a pivotal role in mobilization of P from P-sorbing soil. Because the world P reserves are being depleted whilst vast amounts of P are stored in fertilized soils, there is a growing need for crops with a high efficiency of P acquisition. Some Australian and African native species as well as some existing crops have traits that would be highly desirable for future crops. The possibilities of introducing P-acquisition-efficient species in new cropping and pasture systems are explored. In addition, possible strategies to introduce traits associated with a high P-acquisition efficiency into future crop species are discussed.
