Marssonina leaf spot disease of poplar (MLDP), caused by the hemibiotrophic pathogen Marssonina brunnea, frequently results in damage to many poplar species. In nature, two formae speciales of M. brunnea exist that are susceptible to different poplar subgenera. Marssonina brunnea f. sp. monogermtubi infects poplar hosts from Populus sect. Aigeiros (Aig), while M. brunnea f. sp. multigermtubi al...

The effects of pH and sulfonated lignin (SL) on the saccharification of enzymatic hydrolysis were investigated using acid bisulfite (AS)and green liquor (GL)-pretreated poplar as substrates. The enzymatic sugar conversions of ASand GL-pretreated poplar could reach high levels at pH 4.8. The sugar conversions of both ASand GL-pretreated poplar solids increased when hydrophilic SL was used as an ...

Global climate change is heavily affected by an increase in CO2. As one of several efforts to cope with this, research on poplar, a representative, fast growing, and model organism plants, actively underway. The effects elevated atmospheric CO2 the metabolism, growth, transcriptome poplar were investigated predict productivity environment where concentrations are increasing. Poplar trees grown ...

OSCA  (Hyperosmdality-gate calcium-permeable channels) is a cation channel protein. By participating in sensing changes extracellular osmotic potential, it induces an increase Ca 2+  concentration, regulates and plays important role hypertonic stress induction. However, there are few studies on the  OSCA  genes of poplar. In this study, 16   genes sequenc...

Background: Poplar tree plantations for wood production are part of a worldwide growing trend, especially in moist soil sites. Harvesting operations sites such as poplar require more study detailed and increased knowledge on environmental economic aspects issues. Methods: In this study, the effects moisture content (dry vs. moist) productivity, cost, emissions greenhouse gases (GHG) caused by d...

Many woody perennials, such as poplar (Populus deltoides), are not able to form flower buds during the first several years of their life cycle. They must undergo a transition from the juvenile phase to the reproductive phase to be competent to produce flower buds. After this transition, trees begin to form flower buds in the spring of each growing season. The genetic factors that control flower...

A family of peptides inducing rapid pH alkalinization in hybrid poplar (Populus trichocarpa x Populus deltoides) cell culture medium was isolated from hybrid poplar leaves. Five related approximately 5-kD peptides were purified by high-performance liquid chromatography and analyzed by matrix-assisted laser desorption ionization-mass spectrometry. The N-terminal sequence of one of the isolated p...

BACKGROUND The N-terminal protein processing mechanism (NPM) including N-terminal Met excision (NME) and N-terminal acetylation (N(α)-acetylation) represents a common protein co-translational process of some eukaryotes. However, this NPM occurred in woody plants yet remains unknown. METHODOLOGY/PRINCIPAL FINDINGS To reveal the NPM in poplar, we investigated the N(α)-acetylation status of popl...

This study evaluates the edgewise bending moment capacity of the four most frequently used middle joints in the upholstered furniture frames. The research included the following joints: Mortise and Tenon, double Dowel, Corner Blocks and double Gusset Plates, designed in the form of middle joints and made of beech and poplar solid wood. The test results indicated that regarding the edgewise bend...
