The factors that contribute to and maintain hybrid zones between distinct species are highly variable, depending on hybrid origins, frequencies and fitness. In this study, we aimed to examine genetic origins, compositions and possible maintenance of Populus × jrtyschensis, Cited by: Certain species of Poplar are a valuable source of propolis for honey bees. The spring catkins may be visited for pollen and the spores of a parasitic rust fungus may be an alternative protein source in times when pollen is in short supply.
This page lists the names of all species in the Populus Genus, most are commonly known in English as Poplars, and some are known as Aspens and species are listed on this page using the Botanical method of classifying plants, the Populus Genus is divided into Sections, and each Populus species belongs to only one Section.. These sections are groups of Populus species that are. The transgenic plantlets along with the WT were grown for 3 weeks in hydroponic systems and afterwards transferred to pots (3 L) as described in Müller et al. with the difference that a mixture of soil (Fruhstorfer Erde Type N, Hawite Gruppe GmbH, Vechta, Germany) and sand (one part coarse sand Ø – mm and one part fine sand Ø 0 Cited by: 7.
Poplars (Populus deltoides Bartr. ex Marsh) accumulate a kD bark storage protein (BSP) in phloem parenchyma and xylem ray cells during autumn and winter. Accumulation of poplar BSP is associated with short-day (SD) photoperiods. Poplar BSP shares sequence similarity with the product of the wound-inducible poplar gene win4. The influence of nitrogen availability and photoperiod on the Cited by: English physician and apothecary Nicholas Culpeper ( - ) in his book "Complete Herbal" PROPERTIES OF POPLAR TRADITIONAL USES The use of poplar for its medicinal properties is not new.

Barcoding Poplars (Populus L.) from Western China Article (PDF Available) in PLoS ONE 8(8):e August with Reads How we measure 'reads'. Abstract. Poplars are ideal for phytoremediation because of their high water usage, fast growth, and deep root systems. We measured in and the sapflow of hybrid poplars (Populus nigra L.× P.

= book spp.) belong to tree species with the highest assimilation capacity among woody plants, reaching up to 15–25 mg CO 2 dm −2 h −1 , which makes them attractive and useful for domestication. Poplar breeders use widely different Author: Marzena Niemczyk, Yue Hu, Barb R.
Thomas. Abstract. Poplars (genus Populus, family Salicaceae) consist of more than 30 species widely distributed in temperate and Poplars--Populus L. = book regions of the northern hemisphere (FAO ).The varied uses of Populus include pulpwood, plywood, and match production.
Due to the rapid growth rate, this species has gained importance as an energy plantation (Hall et al. ), this makes Populus a valuable tree Cited by: 1. In this work, we studied similarities and differences between 70% ethanol in water extract (70EE) and essential oils (EOs) obtained from propolis, black poplars (Populus nigra L.) and aspens (P.
tremula L.) to ascertain which of these is a better indicator of the plant species used by bees to collect propolis precursors. Composition of 70EE was analyzed by UPLC-PDA-MS, while GC-MS was used to Cited by: 5. Populus nigra L., popularly known as black poplar, is a tree with short longevity from Salicaceae family, and grows in Brazil, North America, Southern and Central Europe, Central Asia, Siberia and.
poplars (Populus sp.) and willows (Salix sp.), are early successional tree species able to colonize nutrient-poor environments, and are increasingly important for bioenergy, wood products, and environmental services (7). A common natural habitat for poplar and willow is the riparian zone where regular flooding deposits cobble and sand.
The genus Populus belongs to the family Salicaceae and includes 34 species which are interspersed throughout the forests of the temperate and cold regions of the northern hemisphere.
Poplars are in general dioecious plants, with male and female flowers on separate by: 4. Barcoding Poplars (Populus L.) from Western China BackgroundPopulus is an ecologically and economically important genus of trees, but distinguishing between wild species is relatively difficult due to extensive interspecific hybridization and introgression, and the high level of.
Hybrid poplars (Populus nigra L. × Populus maximowiczii A.) were genetically modified through antisense insertion of the 4-coumarate:coenzyme A ligase (4CL) gene. Compositional changes in response to this genetic change were measured in the field after 2 and 3 years of growth.
The stem samples were treated with either green liquor or dilute acid pretreatments, representing alkaline and Cited by: 4. Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar / ˈ p ɒ p.

Crandall, EditorCited by: Young hybrid poplars (Populus tremula×alba) were cultivated under different ozone concentrations (50, and nl l −1).
As upright poplars usually develop tension wood in a non-set pattern, the trees were bent in order to induce tension wood formation on the upper side of the stem and normal or opposite wood on the lower by: Cuttings were collected from balsam poplars (Populusbalsamifera L.) representing 21 populations in Minnesota, Wisconsin, and Michigan, and a replicated nursery trial containing clones was height, phenology, leaf morphology, and resistance to damaging agents were evaluated during the second growing season, and genetic and phenotypic variances and covariances among Cited by: Cytochromes P (CYPs) are potential enzymes responsible for hydroxylation of many xenobiotics and endogenous chemicals in living organisms.
It has been found that 4-monochlorobiphenyl (PCB3), mainly an airborne pollutant, can be metabolized to hydroxylated transformation products (OH-PCB3s) in whole poplars. However, the enzymes involved in the hydroxylation of PCB3 in whole poplars have not.
Poplars, cottonwoods and aspens are all members of the Populus genus, and all are quite tall. The black cottonwood (Populus trichocarpa) can grow to a height of feet and is hardy Missing: book. While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts.

Sphinx is a protein loop modelling algorithm that generate high-accuracy predictions and decoy sets enriched with near-native loop conformations. Given a protein structure, location of the loop to be modelled and the sequence of that loop, it searches a database of fragments for sections of other proteins that are shorter than the target loop Interface: Web user interface.
Caffeic acid O -methyltransferase (COMT) catalyzes preferentially the methylation of 5-hydroxyconiferaldehyde to sinapaldehyde in monolignol biosynthesis. Here, we have compared HPLC profiles of the methanol-soluble phenolics fraction of xylem tissue from COMT-deficient and control poplars (Populus spp.), using statistical analysis of the peak by: An excerpt from that post, "Plant Stories from the Sagebrush Salve": "I thought my first experience of Cottonwood was on the west coast.
