AP2/ERF genes encode transcriptional regulators with a variety of functions in plant growth and development and in response to biotic and abiotic stresses. To date, there are no detailed classification and expression profiles for AP2/ERF genes in Salix. In this study, a comprehensive computational analysis identified 173 AP2/ERF superfamily genes in willow (Salix arbutifolia), by using in silic...
In a greenhouse experiment, two strains of plant growth promoting rizobacteria (PGPR) mixture of (ICARDA-441 and ARC-202) as seed inoculants, and white willow (Salix alba) extract as foliar and seed treatment were tested for induction systemic acquired resistance (SAR) in faba bean plants against Bean yellow mosaic virus (BYMV). The results demonstrated that BYMV challenged plants emerged from ...
The aim of this study was to investigate and to compare the extractability, bioaccessibility, and bioavailability in vitro of antioxidative compounds from bark of selected Salix species: S. alba (SA), S. daphnoides (SD), S. purpurea (SP), and S. daphnoides x purpurea (SDP) hybrid willow clones originating from their natural habitats and cultivated on the sandy soil. The highest amount of phenol...
506 Abstract: Present study was to investigate antioxidant and anti inflammatory effects of salix tetrasperma Roxb in rats. The Hydroalcoholicic extract of salix tetrasperma Roxb (100 and 200 mg/kg body weight) was studied for anti-inflammatory in animal models. The activity was studied in carragenan induced rats paw edema against indomethacin as standard, and it showed significant anti inflamm...
Salix matsudana Koidz. is a deciduous, rapidly growing, and drought resistant tree and is one of the most widely distributed and commonly cultivated willow species in China. Currently little transcriptomic and small RNAomic data are available to reveal the genes involve in the stress resistant in S. matsudana. Here, we report the RNA-seq analysis results of both transcriptome and small RNAome d...
The success of the short-rotation coppice system in biomass willow (Salix spp.) relies on the activity of the shoot-producing meristems found on the coppice stool. However, the regulation of the activity of these meristems is poorly understood. In contrast, our knowledge of the mechanisms behind axillary meristem regulation in Arabidopsis (Arabidopsis thaliana) has grown rapidly in the past few...
Ambient energy, niche conservatism, historical climate stability and habitat heterogeneity hypothesis have been proposed to explain the broad-scale species diversity patterns and species compositions, while their relative importance have been controversial. Here, we assessed the relative contributions of contemporary climate, historical climate changes and habitat heterogeneity in shaping Salix...
این مطالعه آنالیز فیلوژنتیکی داده های توالی های nrdna its برای 62 تاکسون شامل 55 گونه salix و دو گونه ی populus به عنوان برون گروه و توالی های trnl-f کلروپلاستی برای 14 گونه salix استفاده شد. آنالیز فیلوژنتیکی با استفاده از روشهای بیشینه ی صرفه جوئی (maximum parsimony) و bayesianانجام گرفت. فیلوژنی حاصل از توالی های nrdna its نشان داد که همه ی پنج زیرجنس رایج salix به استثنای زیرجنس مونوتیپیکl...
سنک بید و صنوبر،monosteira unicostata ، از آفات مهم گونهﻫﺎی مختلف بید و صنوبر در بسیاری از نقاط کشور به شمار میﺭود که به طور مستقیم به برگﻫﺎ و غیرمستقیم روی کیفیت و کمیت چوب این درختان خسارت وارد میﺳﺎزد. بهمنظور بررسی میزان مقاومت گونهﻫﺎی مختلف بید به این آفت، سازوکار مقاومت آنتیﺯنوزی 11 گونه بید در شرایط آزمایشگاهی در سال 1387در ﻣﺆسسه تحقیقات جنگلﻫﺎ و مراتع تهران بررسی گردید. قلمهﻫﺎیی سه تا ش...
4-Coumarate:CoA ligase (4CL) genes are critical for the biosynthesis of plant phenylpropanoids. Here we identified 20 4CL genes in the genomes of two desert poplars (Populus euphratica and P. pruinosa) and salt-sensitive congener (P. trichocarpa), but 12 in Salix suchowensis (Salix willow). Phylogenetic analyses clustered all Salicaceae 4CL genes into two clades, and one of them (corresponding ...
