Host jumps shaped the diversity of extant rust fungi (Pucciniales).
The aim of this study was to determine the evolutionary time line for rust fungi and date key speciation events using a molecular clock. Evidence is provided that supports a contemporary view for a recent origin of rust fungi, with a common ancestor on a flowering plant. Divergence times for > 20 genera of rust fungi were studied with Bayesian evolutionary analyses. A relaxed molecular clock wa...
متن کاملOnline identification guides for Australian smut fungi (Ustilaginomycotina) and rust fungi (Pucciniales)
Interactive identification keys for Australian smut fungi (Ustilaginomycotina and Pucciniomycotina, Microbotryales) and rust fungi (Pucciniomycotina, Pucciniales) are available online at http://collections.daff.qld.gov.au. The keys were built using Lucid software, and facilitate the identification of all known Australian smut fungi (317 species in 37 genera) and 100 rust fungi (from approximate...
متن کاملESEfinder: a web resource to identify exonic splicing enhancers
Point mutations frequently cause genetic diseases by disrupting the correct pattern of pre-mRNA splicing. The effect of a point mutation within a coding sequence is traditionally attributed to the deduced change in the corresponding amino acid. However, some point mutations can have much more severe effects on the structure of the encoded protein, for example when they inactivate an exonic spli...
متن کاملNutrient Uptake in Rust Fungi
Nutrient uptake in obligate parasitism was recently reviewed by Bushnell and Gay (5) for the powdery mildews. In the rust fungi, the experimental approach to solving this question is quite different, because the fungus mycelium grows only in restricted areas within the leaf. The rust pustules act as foci for the accumulation of many metabolites. The fungus derives nutrients by alteration of the...
متن کاملThe Rust Fungi
The rust fungi are a monophyletic group of approximately 7000 species in the basidiomycota and are highly specialized obligate parasites of plants. The life cycle of rusts can be complex. Some rusts have up to five spore stages that alternate between haploid and dikaryotic nuclear conditions and that can occur on two taxonomically unrelated host plants. The rusts have evolved specialized struct...
