Nicotine alkaloid levels, and nicotine to nornicotine conversion, in Australian Nicotiana species used as chewing tobacco
A range of endemic Nicotiana species are chewed as a smokeless tobacco by several Aboriginal populations of Australia. In tobacco research, nicotine to nornicotine conversion is important because nornicotine lowers tobacco quality and is detrimental to health. A diverse group of cytochrome P450 genes with different transcriptional regulations are involved in this conversion. The primary aims of...
متن کاملThe Biosynthesis of a Novel Nicotine Alkaloid in the Trichomes of Nicotiana stocktonii.
N-Hydroxyacylnornicotine, newly discovered from fresh plant tissue, was found entirely in the trichome exudate produced at the epidermis of the aerial part of Nicotiana stocktonii. Nicotine and nornicotine, but not N-hydroxyacylnornicotine, were present inside of the trichomes as well as other internal parts of the plant. Only nicotine was found in bleeding sap squeezed from cut roots or stems....
متن کاملThe Only African Wild Tobacco, Nicotiana africana: Alkaloid Content and the Effect of Herbivory
Herbivory in some Nicotiana species is known to induce alkaloid production. This study examined herbivore-induced defenses in the nornicotine-rich African tobacco N. africana, the only Nicotiana species indigenous to Africa. We tested the predictions that: 1) N. africana will have high constitutive levels of leaf, flower and nectar alkaloids; 2) leaf herbivory by the African bollworm Helicoverp...
متن کاملConsistency of Nicotiana attenuata's herbivore- and jasmonate-induced transcriptional responses in the allotetraploid species Nicotiana quadrivalvis and Nicotiana clevelandii.
We examined the consistency of the native diploid Nicotiana attenuata (Na)'s herbivore-induced transcriptional changes in the two allotetraploid natives, Nicotiana clevelandii (Nc) and Nicotiana quadrivalvis (Nq), which are thought to be derived from hybridizations with an ancestral Na. An analysis of nuclear-encoded chloroplast-expressed Gln synthetase gene (ncpGS) sequences found strong simil...
متن کاملThe species composition and nutrition of dominant species of fish of Absheron Gulfs of the Caspian Sea
The analysis of net catches made in Absheron Gulfs of the Caspian Sea during 2011-2012 is provided. The ichthyofauna of Absheron Gulfs, including 26 species found in the North Gulf, and 33 species and subspecies found in the South Gulf was studied for the first time. A taxonomical and ecological diversity of the fish fauna of North and South Absheron Gulfs is characterized. The peculiarities of...
