Characterization of BspA, a major boiling-stable, water-stress-responsive protein in aspen (Populus tremula).
We identified a novel 66 kDa boiling-stable protein (BspA) in cultured shoots of aspen (Populus tremula L.) which was highly expressed in response to gradual water stress. The BspA protein, which was highly expressed as early as 1 h after initiation of a drought treatment, accumulated during progressive water stress, decreased on rehydration, and was expressed in response to abscisic acid (ABA)...
متن کاملMolecular Identification and Karyological Analysis of a Rampant Aspen Populus tremula L. (Salicaceae) Clone
A rampant highly heterozygous aspen (Populus tremula L.) clone "Meshabash" has been revealed in course of population genetic diversity analysis in a native stand in the Republic of Tatarstan, Russia. Here we report the results of karyological analysis showing that this highly vigorous clone is diploid (2n = 38) while typically triploid aspen demonstrates increased growth rate and resistance to ...
متن کاملA novel antioxidant phenyl disaccharide from Populus tremula knotwood.
The complete characterization of two compounds obtained from the acetone extract of Populus tremula knotwood has been was achieved using LC-DAD-MS, MS/MS, IR and NMR. The new compounds were unequivocally identified as a mixture of the ester isomers of the (E) and (Z) p-coumarate of 1-O-rutinose. The isomers showed the capacity to inhibit lipid peroxidation induced by tert-butylhydroperoxide and...
متن کاملMolecular Population Genetics of Elicitor-Induced Resistance Genes in European Aspen (Populus tremula L., Salicaceae)
Owing to their long life span and ecological dominance in many communities, forest trees are subject to attack from a diverse array of herbivores throughout their range, and have therefore developed a large number of both constitutive and inducible defenses. We used molecular population genetics methods to examine the evolution of eight genes in European aspen, Populus tremula, that are all ass...
متن کاملMolecular population genetics of herbivore-induced protease inhibitor genes in European aspen (Populus tremula L., Salicaceae).
Plants defend themselves against the attack of natural enemies by using an array of both constitutively expressed and induced defenses. Long-lived woody perennials are overrepresented among plant species that show strong induced defense responses, whereas annual plants and crop species are underrepresented. However, most studies of plant defense genes have been performed on annual or short-live...
