Microbiol Resour Announc
. 2019 Jul;

PMID: 31320443
Diverse strains of () have been isolated from a variety of environments, most frequently in association with both plants and fungi. Motivated by the lack of genomic information for strains...

PMID: 30395602
The contribution of epigenetic variation to phenotypic variation is unclear. Imprinted genes, because of their strong association with epigenetic modifications, represent an opportunity for the discovery of such phenomena. In...

PLoS Genet
. 2015 Apr;
11(3):e1005142.
PMID: 25826366
Genomes must balance active suppression of transposable elements (TEs) with the need to maintain gene expression. In Arabidopsis, euchromatic TEs are targeted by RNA-directed DNA methylation (RdDM). Conversely, active DNA...

Elife
. 2014 Jul;
3:e03198.
PMID: 24994762
Imprinted gene expression occurs during seed development in plants and is associated with differential DNA methylation of parental alleles, particularly at proximal transposable elements (TEs). Imprinting variability could contribute to...

Curr Opin Plant Biol
. 2012 Sep;
15(5):530-5.
PMID: 23000433
Until recently, only a handful of imprinted genes, or genes with parent-of-origin dependent expression patterns, were known in plants. Study of these genes yielded key insights into mechanisms of monoallelic...

PMID: 22307647
Plant genomes contain large numbers of cell surface leucine-rich repeat (LRR) and intracellular nucleotide binding (NB)-LRR immune receptors encoded by resistance (R) genes that recognize specific pathogen effectors and trigger...

PMID: 20409178
Two fundamental types of polyploids are known: allopolyploids, in which different parental chromosome sets were combined by ancestral hybridization and duplication; and autopolyploids, which derive from multiplication of the same...

J Biol
. 2009 May;

PMID: 19439050
The merger of evolutionarily diverged genomes to form a new polyploid genetic system can involve extensive remodeling of gene regulation. A recent paper in BMC Biology provides important insights into...

PMID: 18725969
Background: Whole genome duplication, which results in polyploidy, is a common feature of plant populations and a recurring event in the evolution of flowering plants. Polyploidy can result in changes...
