Massive Expansion of Gypsy-Like Retrotransposons in Microbotryum Fungi
Transposable elements (TEs) are selfish, autonomously replicating DNA sequences that constitute a major component of eukaryotic genomes and contribute to genome evolution through their movement and amplification. Many fungal genomes, including the anther-smut fungi in the basidiomycete genus Microbotryum, have genome defense mechanisms, such as repeat-induced point mutation (RIP), which hypermu...
متن کاملGypsy-like retrotransposons in Pyrenophora: an abundant and informative class of molecular markers.
This paper describes the development of S-SAP (sequence-specific amplified polymorphism) using a primer derived from the LTR (long terminal repeat) of the Pyggy retrotransposon isolated from Pyrenophora graminea. Fragments were amplified by S-SAP from different Pyrenophora spp., indicating the presence of Pyggy-like sequences in these genomes. The bands were highly polymorphic between isolates ...
متن کاملPolyploidization Altered Gene Functions in Cotton (Gossypium spp.)
Cotton (Gossypium spp.) is an important crop plant that is widely grown to produce both natural textile fibers and cottonseed oil. Cotton fibers, the economically more important product of the cotton plant, are seed trichomes derived from individual cells of the epidermal layer of the seed coat. It has been known for a long time that large numbers of genes determine the development of cotton fi...
متن کاملSurface plasmon resonance detection of transgenic Cry1Ac cotton ( Gossypium spp.).
The detection and identification of genetically modified (GM) plants are challenging issues that have arisen from the potential negative impacts of extensive cultivation of transgenic plants. The screening process is a long-term focus and needs specific detection strategies. Surface plasmon resonance (SPR) has been used to detect a variety of biomolecules including proteins and nucleic acids du...
متن کاملProgress in genome sequencing will accelerate molecular breeding in cotton (Gossypium spp.)
Cotton (Gossypium spp.) is the single most important spinning fiber that has economic significance worldwide. Cotton is one of the most value-added crops and an excellent model system for the analysis of polyploidization and cell development. Thus, the Cotton Genome Consortium has made rapid and significant progress in whole genome sequencing studies in the last decade. Developments in cotton g...
