Characteristics of the Diploid, Triploid, and Tetraploid Versions of a Cannabigerol-Dominant F Hybrid Industrial Hemp Cultivar, 'Stem Cell CBG'.

Hemp ( L.) has recently become an important crop due to the growing market demands for products containing cannabinoids. Unintended cross-pollination of crops is one of the most important threats to cannabinoid production and has been shown to reduce cannabinoid yield.

SNP in Potentially Defunct Tetrahydrocannabinolic Acid Synthase Is a Marker for Cannabigerolic Acid Dominance in L.

The regulation of cannabinoid synthesis in is of increasing research interest as restrictions around the globe loosen to allow the plant's legal cultivation. Of the major cannabinoids, the regulation of cannabigerolic acid (CBGA) production is the least understood. The purpose of this study was to elucidate the inheritance of CBGA dominance in and describe a marker related to this chemotype.

The History of Taxonomy, the Rise of Phylogenetics, and Implications for Species Recognition.

is one of the oldest, most well studied, and most economically important fungal taxa. Nonetheless, many species in this genus have remained obscured for nearly 300 years because of the difficulty in distinguishing these species by conventional mycological methods. Aided by the use of phylogenetic tools, the genus is currently undergoing a taxonomic revolution.

Genetic analysis reveals unprecedented diversity of a globally-important plant pathogenic genus.

Genus Botrytis contains approximately 35 species, many of which are economically-important and globally-distributed plant pathogens which collectively infect over 1,400 plant species. Recent efforts to genetically characterize genus Botrytis have revealed new species on diverse host crops around the world. In this study, surveys and subsequent genetic analysis of the glyceraldehyde-3-phosate dehydrogenase (G3PDH), heat-shock protein 60 (HSP60), DNA-dependent RNA polymerase subunit II (RPB2), and necrosis and ethylene-inducing proteins 1 and 2 (NEP1 and NEP2) genes indicated that Botrytis isolates collected from peony fields in the United States contained more species diversity than ever before reported on a single host, including up to 10 potentially novel species.

Botrytis euroamericana, a new species from peony and grape in North America and Europe.

A novel species of Botrytis isolated from peony in Alaska, USA, and grape in Trento District, Italy, was identified based on morphology, pathogenicity, and sequence data. The grape and peony isolates share sequence homology in the glyceraldehyde-3-phosphate dehydrogenase (G3PDH), heat shock protein 60 (HSP60), DNA-dependent RNA polymerase subunit II (RPB2), and necrosis- and ethylene-inducing protein 1 and 2 (NEP1 and NEP2) genes that place them in a distinct group closely related to B. aclada, a globally distributed pathogen of onions.
