poplars are classified as fast-growing and slightly water tolerant species which will be weakened with decreased growth in extreme moisture or drought lands. the plantation of these species in agricultural lands and at the edge of rivers and water canals has currenthy an important role in both economical and social development of rural regions. the purpose of this study was to investigate and c...

Protein sequences were compared among Arabidopsis, Oryza and Populus to identify differential gene (DG) sets that are in one but not the other two genomes. The DG sets were screened against a plant transcript database, the NR protein database and six newly-sequenced genomes (Carica, Glycine, Medicago, Sorghum, Vitis and Zea) to identify a set of species-specific genes (SS). Gene expression, pro...

A new species of Botryozyma, Botryozyma mucatilis, was isolated from the surface of free-living nematodes, Panagrellus dubius, inhabiting slime flux from hybrid poplars, Populus deltoidesxtrichocarpa, in Oregon, USA. This species was discovered in relatively close proximity to the teleomorphic species Ascobotryozyma americana and Ascobotryozyma cognata, both collected from P. dubius nematodes i...

Phloem exudate collected from hybrid poplar (Populus trichocarpa x Populus deltoides) was estimated to have more than 100 proteins, of which 48 were identified using LC-MS/MS. Comparative two-dimensional gel electrophoresis demonstrated that two phloem exudate proteins were significantly (P<0.05) upregulated 24 h after leaf wounding. These were identified as pop3/SP1 and a thaumatin-like protei...

In this paper we compare leaf traits and spectral reflectance for sunlit andshaded leaves of Populus tremuloides and Populus balsamifera during autumnsenescence using information derived from an Analytical Spectral Devise (ASD) FullRange spectrometer. The modified simple ratio (mSR705) and modified normalizeddifference index (mND705) were effective in describing changes in chlorophyll contentov...

این تحقیق با هدف تعیین سازگارترین کلن‌ها با تولید زیاد چوب در ایستگاه تحقیقات صنوبر و درختان سریع‌الرشد واقع در شهر بلداجی استان چهارمحال و بختیاری اجرا گردیده است. به‌منظور اجرای این تحقیق از 12 کلن (تیمار) غیر بومی تاج‌باز از گونه‌های Populus euramericana و Populus deltoides استفاده گردید. کلن‌های یاد شده با فاصله 4×4 متر و در قالب طرح آماری بلوک‌های کامل تصادفی و در سه تکرار کشت شدند. اطلاعا...

از جمله گونه های زود رشد که در گذشته بیشتر به صورت خالص کاشته شده اند، صنوبرها می یاشند که اخیرا کاشت آمیخته آنها با گونه های تثبیت کننده ازت، برای حاصل خیزی خاک پیشنهاد می شود به همین منظور درختان صنوبر دلتوئیدس (populus deltoids)3ساله با گونه بادام زمینی (arachis hypogaea l.) در زمین های ایستگاه تحقیقات زراعی فخرآباد لشت نشاء در قالب طرح بلوک های کامل تصادفی با پنج تیمار و سه تکرار کاشت شده ا...

Background Populus natural variants have been shown to realize a broad range of sugar yields during saccharification, however, the structural features responsible for higher sugar release from natural variants are not clear. In addition, the sugar release patterns resulting from digestion with two distinct biological systems, fungal enzymes and Clostridium thermocellum, have yet to be evaluated...

Phenolic metabolites that contain salicylic acid (SA)-like moieties are major non-structural constituents in Populus leaves, shoots and roots. These so-called phenolic glycosides (PGs) are taxonomically limited to the Salicaceae, where they are known to mitigate insect and animal herbivory. SA itself is an important signaling molecule in plant defense and abiotic stress responses, and is derive...
