Background: Theobroma cacao L., the source of cocoa, is a crop of significant economic value around the world. To facilitate the study of gene function in cacao we have developed a rapid Agrobacterium-mediated transient genetic transformation protocol. Here we present a detailed methodology for our transformation assay, as well as...
Background: Pre-genomic and post-genomic studies demonstrate that chlamydiae actively recombine in vitro and
in vivo, although the molecular and cellular biology of this process is not well understood. In this study, we
determined the genome sequence of twelve Chlamydia trachomatis recombinants that were generated in vitro
under antibiotic selection. These...
BACKGROUND: Targeted capture of genomic regions reduces sequencing cost while generating higher coverage by
allowing biomedical researchers to focus on specific loci of interest, such as exons. Targeted capture also has the
potential to facilitate the generation of genomic data from DNA collected via saliva or buccal cells. DNA samples...
Background
Two major mycoparasitic lineages, the family Hypocreaceae and the genus Tolypocladium, exist within the fungal order, Hypocreales. Peptaibiotics are a group of secondary metabolites almost exclusively described from Trichoderma species of Hypocreaceae. Peptaibiotics are produced by nonribosomal peptide synthetases (NRPSs) and have antibiotic and antifungal activities. Tolypocladium species are...
Background:
Mapping and map-based cloning of genes that control agriculturally and economically important traits remain great challenges for plants with complex highly repetitive genomes such as those within the grass tribe, Triticeae. Mapping limitations in the Triticeae are primarily due to low frequencies of polymorphic gene markers and poor genetic...
Background: Short RNAs, and in particular microRNAs, are important regulators of gene
expression both within defined regulatory pathways and at the epigenetic scale. We investigated
the short RNA (sRNA) population (18-24 nt) of the transcriptome of green leaves from the
sequenced Populus trichocarpa using a concatenation strategy in combination with...
Background: Potato virus Y (PVY) is one of the most important plant viruses affecting potato production. The
interactions between potato and PVY are complex and the outcome of the interactions depends on the potato
genotype, the PVY strain, and the environmental conditions. A potato cultivar can induce resistance to a...
Background: Corals are capable of launching diverse immune defenses at the site of direct contact with pathogens, but the molecular mechanisms of this activity and the colony-wide effects of such stressors remain poorly understood. Here we compared gene expression profiles in eight healthy Acropora hyacinthus colonies against eight colonies exhibiting...
Background:
Coral reef ecosystems are declining in response to global climate change and anthropogenic impacts. Yet patterns of standing genetic variation within cnidarian species, a major determinant of adaptive potential, are virtually unknown at genome-scale resolution. We explore patterns of genome-wide polymorphism and identify candidate loci under selection in the...
Background: Supernumerary chromosomes have been found in many organisms. In fungi, these “accessory” or “dispensable” chromosomes are present at different frequencies in populations and are usually characterized by higher repetitive DNA content and lower gene density when compared to the core chromosomes. In the reference strain of the wheat pathogen,...
