The depleting petroleum reserve, increasingly severe energy crisis, and global climate change are reigniting enthusiasm for seeking sustainable technologies to replace petroleum as a source of fuel and chemicals. In this paper, the efficiency of the MVA pathway on isoprene production has been improved as follows: firstly, in order to increase MVA production, the source of the "upper pathway" wh...
Complete Populus genome sequences are available for the nucleus (P. trichocarpa; section Tacamahaca) and for chloroplasts (seven species), but not for mitochondria. Here, we provide the complete genome sequences of the chloroplast and the mitochondrion for the clones P. tremula W52 and P. tremula x P. alba 717-1B4 (section Populus). The organization of the chloroplast genomes of both Populus cl...
We sought to quantify changes in tree species composition, forest structure and aboveground forest biomass (AGB) over 76 years (1930-2006) in the deciduous Black Rock Forest in southeastern New York, USA. We used data from periodic forest inventories, published floras and a set of eight long-term plots, along with species-specific allometric equations to estimate AGB and carbon content. Between...
Populus alba Villafranca clone was chosen for a proof of concept study to determine the potential uptake and accumulation of antibiotics by trees. Plants were grown hydroponically and irrigated with a recirculating Hoagland's nutrient solution (control) and Hoagland's nutrient solution fortified with erythromycin at 0.01, 0.1 and 1mgL(-1). After 3 and 28days of treatment, poplar plants were sep...
اندوخته شدن کربن در زیتوده گیاهی ساده ترین و به لحاظ اقتصادی عملی ترین راهکار برای کاهش دی اکسید کربن اتمسفری است. این پایان نامه با هدف مقایسه توان ذخیره کربن درخت و خاک و نیز روابط آلومتری چهار گونه صنوبر شامل (populus alba و p.nigra و دو گونه هیبرید p. alba × euphratica و p. euphratica × alba که از این پس در تمام این پایان نامه، هیبرید ها نیز گونه خوانده خواهند شد) کاشته شده در ایستگاه تحقیق...
