Partially unacylated new oligomeric hydrolyzable tannins, nilotinin T2 (1, trimer) and nilotinin Q1 (2, tetramer), together with four known trimers, nilotinin T1 (3) and hirtellins T1-T3 (4-6), and a dimer, tamarixinin B (7), were isolated from the aqueous acetone extracts of leaves of Tamarix nilotica. Among them, the new trimer 1 and the known trimers 4 and 6, in addition to the partially una...

NAC (NAM, ATAF1/2, and CUC2) proteins play critical roles in many plant biological processes and environmental stress. However, NAC proteins from Tamarix hispida have not been functionally characterized. Here, we studied a NAC gene from T. hispida, ThNAC13, in response to salt and osmotic stresses. ThNAC13 is a nuclear protein with a C-terminal transactivation domain. ThNAC13 can bind to NAC re...

Tamarisk species are shrubs or small trees considered by some to be among the most aggressively invasive and potentially detrimental exotic plants in the United States. Although extensively studied in the southern and interior west, northwestern (Oregon, Washington, and Idaho) distribution and habitat information for tamarisk is either limited or lacking. We obtained distribution data for the n...

A TLC method with densitometric detection for identification and quantitation of indole compounds in methanolic extracts of fruiting bodies of Armillaria mellea (Vahl.) P. Kumm. (Basidiomycota)--Honey mushroom has been developed. The TLC method with densitometric detection was validated for determination of tryptamine and serotonin contents. The use of this chromatographic-densitometric method ...

Abstract. The purpose is to study the features of adaptive reactions pigment system plants in stress conditions Astrakhan region. In role diagnosing state plants, physiological and biochemical indicators are used, which reflect body's ability adapt changing environmental conditions. Methods. studies, methods observation, description objects study, spectrophotometric determination quantitative c...

among scholars. Indeed, the time now seems ripe for a Paris medicine web page, especially since many of the key French texts have become available on-line through the Gallica service of the Bibliotheque nationale de France (http://gallica.bnf.fr/). We cannot all meet in Paris, but as a virtual academic community we can perhaps help reconstruct Paris medicine, building on the important work of H...

BACKGROUND Laccases are multicopper oxidases with high potential for environmental and industrial applications. Low-cost laccase production could be achieved by solid state fermentation on agro-industrial by-products. METHODS A number of agro-industrial solid wastes were tested as support-substrate for laccase production by Coriolopsis gallica under solid-state fermentation (SSF) conditions. ...
