Genetically modified plants are usually produced using tissue culture, but techniques used to modify a plant genome also affect its epigenome.

Little is known about the genome of Anthurium other than chromosome observations, which frequently indicate supernumerary (“B”) chromosomes. New genome size estimates for 34 species and nine cultivars presented here provide insights into genome organization and evolution in this very large genus.
This paper compiles and discusses all currently available nuclear genome size data for red algae in relation to their most recent taxonomic classification.
The genome size and organization of the important medicinal plant Catharanthus roseus is shown to correspond to 1C = 0.76 pg (~738 Mbps) and 2n=16 chromosomes. The data in this recently published paper provide a sound basis for future studies including cytogenetic mapping, genomics and breeding.
Molecular genetic diversity and population structure analysis were used to clarify the controversial botanical classification of Stylosanthes guianensis. In this paper, the accessions were clustered in nine groups, each of which was mainly composed of only one of the four botanical varieties.
Anne Osterrieder has a new series on her blog called Faces of plant cell biologists, where we are asked a series of questions. So far, it has featured Charlotte Carroll (also an AoBBlog.com guest author here), Chris Hawes and Kentaro Tamura, who all answer Anne’s questions is surprisingly contrasting but complementary ways. Today, I have been [...]
There’s been a rash of stories about how new grape varieties will be needed to fight disease if wineries are to keep flowing. As far as I can tell, because I haven’t seen anyone link to the paper, it’s based on Genetic structure and domestication history of the grape and Open Access paper in PNAS [...]
