Epitrix hirtipennis (Melsheimer, 1847) (Coleoptera: Chrysomelidae: Galerucinae: Alticini), a leaf beetle native to North America, is recorded for the first time from Hungary. Several specimens were found on tobacco (Nicotiana tabacum L.) plantations in eastern and central parts of country. Its life cycle importance as pest are briefly discussed.
1. Coproporphyrinogenase was extracted and purified from tobacco (Nicotiana tabacum L.). Enzyme activity was mainly located in mitochondria rather than in chloroplasts. The enzyme was purified by differential centrifugation, ammonium sulphate fractionation, calcium phosphate gel adsorption and dialysis. A 69-fold final purification was obtained. 2. An apparent K(m) value of 3.6x10(-5)m was foun...
Detailed analysis of the expression pattern of seven legumain genes from Nicotiana tabacum L. cv. SNN revealed that it showed neither coincidences with the branches of the phylogenetic tree of legumains nor with their conventional assignment to organs. This agreed well with the fact that, so far, no functional differences could be assigned to the sequence differences reflected in the branches o...
tobacco (nicotiana tabacum l.) is an important industrial crop and its seeds contain significant amounts of oil. the extraction of oil components using solvent at high pressure, or supercritical fluid (scf), has received much attention. in the present study, statistical analyses showed that the average extraction yield of seed oil of five tobacco varieties using sfe was 9.33%, which was higher ...
Tobacco (Nicotiana tabacum L. cv Samsun NN) leaves accumulate a cytoplasmic/nuclear lectin, called Nictaba, in response to methyl jasmonate. To check whether, and if so to what extent, the specific induction of this lectin applies to related species, a collection of 19 Nicotiana species--covering 12 Nicotiana sections and eight Nicotiana tabacum cultivars--was screened for their capability to s...
