Mikania micrantha (Asteraceae: Eupatorieae), widely called mile-a-minute, has been a persistent problem to forestry, plantations and biodiversity conservation in southwestern and northeastern India, as well as in Andaman and Nicobar islands. To supplement the previously imported Trinidad-originating Puccinia spegazzinii (Pucciniales: Pucciniaceae), a different pathotype (IMI 393076) was importe...
In this study we provide a phylogenetically based introduction to the classes and orders of Pucciniomycotina (= Urediniomycetes), one of three subphyla of Basidiomycota. More than 8000 species of Pucciniomycotina have been described including putative saprotrophs and parasites of plants, animals and fungi. The overwhelming majority of these (approximately 90%) belong to a single order of obliga...
Plant diseases caused by fungi and Oomycetes represent worldwide threats to crops and forest ecosystems. Effective prevention and appropriate management of emerging diseases rely on rapid detection and identification of the causal pathogens. The increase in genomic resources makes it possible to generate novel genome-enhanced DNA detection assays that can exploit whole genomes to discover candi...
Gymnosporangium species (Pucciniaceae, Pucciniales) cause serious diseases and significant economic losses to apple cultivars. Most of the reported species are heteroecious and complete their life cycles on two different plant hosts belonging to two unrelated genera, i.e. Juniperus and Malus. However, the phylogenetic relationships among Gymnosporangium species and the evolutionary history of G...
Using de novo assembly of 46 million paired end sequence reads of length 250 bp for a myrtle rust isolate, we have estimated its genome size to be between 103 and 145 Mb and the number of proteins as >19,000. Annotation of the contigs found a very large percentage of proteins are associated with molecular functions of DNA binding or binding in biological processes for DNA integration and RNA-de...
Rust diseases caused by fungi of the order Pucciniales afflict a wide range of plants, including cereals, legumes, ornamentals, and fruit trees, and pose a serious threat to cropping systems and global food security. The obligate parasitic lifestyle of these fungi and their complex life cycles, often involving alternate hosts for the sexual and asexual stages, also make this group of pathogens ...
