Characterization of cDNAs differentially expressed in roots of tobacco (Nicotiana tabacum cv Burley 21) during the early stages of alkaloid biosynthesis.
A set of 60 cDNAs were isolated by subtractive hybridization screening of a phage library using radioactively-labeled probes generated from root mRNAs isolated from tobacco (Nicotiana tabacum cv Burley 21) plants before and 3 days after topping. Among the differentially expressed gene products were full-length and partial cDNAs encoding arginine decarboxylase (ADC), ornithine decarboxylase (ODC...
متن کاملThe Import Demand for U.s. Burley Tobacco in European Markets
One of the chief complaints against the federal importer of burley tobacco. Italy, Greece, South tobacco program is that it sets prices too high Korea, and almost every other burley exporting relative to foreign tobaccos: most foreign burley country import substantial amounts of burley. tobaccos are priced between one-third and oneThese foreign exporters typically import large half the price of...
متن کاملAntioxidant activities of polysaccharide fractions isolated from burley tobacco flowers
The crude polysaccharide extracted from the flowers of burley tobacco hybrid Eyan 1 was fractionated on a Sepharose CL-6B chromatography to get two purified polysaccharide fractions (termed Fr-I and Fr-II). The monocarbohydrate compositions revealed both fractions were heteropolysaccharide. Fr-I was mainly composed of mannose, galactose, ribose and arabinose, while Fr-II was composed of mannose...
متن کاملBurley Tobacco Clubs in Malawi: Nonmarket Institutions for Exports
This paper studies nonmarket institutions that facilitate exports. In Malawi, as in many other developing countries, farmers face numerous constraints that disconnect them from export markets. We explore the role of a local institution, the burley tobacco clubs, in bridging smallholders to exports. Burley clubs potentially enable farmers to increase their tobacco farming productivity by providi...
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...
