Somatic mutations contribute to genotypic diversity in sterile and fertile populations of the threatened shrub, Grevillea rhizomatosa (Proteaceae).
BACKGROUND AND AIMS Grevillea rhizomatosa is a spreading shrub which exhibits multiple breeding strategies within a narrow area in the fire-prone heathlands of eastern Australia. Reproductive strategies include self-compatibility, self-incompatibility and clonality (with and without sterility). The close proximity of contrasting breeding systems provides an opportunity to explore the evolution ...

Marginal populations are commonly expected to be less genetically variable than populations in the central range, which can make them less viable than the latter (Lesica and Allendorf, 1995). The degree of environmental and geographical marginality influences the genetic structure of populations (Johannesson and André, 2006). According to Mayr's (1970) model, the isolation of marginal populatio...
متن کاملEffects of clonality on the genetic variability of rare, insular species: the case of Ruta microcarpa from the Canary Islands
Many plant species combine sexual and clonal reproduction. Clonal propagation has ecological costs mainly related to inbreeding depression and pollen discounting; at the same time, species able to reproduce clonally have ecological and evolutionary advantages being able to persist when conditions are not favorable for sexual reproduction. The presence of clonality has profound consequences on t...
متن کاملClonal genetic structure and diversity in populations of an aquatic plant with combined vs. separate sexes.
Clonality is often implicated in models of the evolution of dioecy, but few studies have explicitly compared clonal structure between plant sexual systems, or between the sexes in dioecious populations. Here, we exploit the occurrence of monoecy and dioecy in clonal Sagittaria latifola (Alismataceae) to evaluate two main hypotheses: (i) clone sizes are smaller in monoecious than dioecious popul...
متن کاملRhynchostomatoid fungi occurring on Proteaceae.
A new ascomycete fungus, with long-necked perithecia having central ostioles and striate ascospores, was isolated from flowerheads of Protea burchellii and P. laurifolia in South Africa and is described here as Rhynchostoma proteae sp. nov. Sequence data obtained from the small-subunit ribosomal DNA (SSU nrDNA) place this fungus with 100% bootstrap support in a clade containing the type species...
