A functional gene microarray was developed and used to investigate phytoplankton community composition and gene expression in the English Channel. Genes encoding the CO2 -fixation enzyme RUBISCO (rbcL) and the nitrate assimilation enzyme nitrate reductase (NR) representing several major groups of phytoplankton were included as oligonucleotide probes on the "phytoarray." Five major groups of euk...
Background: Isoberlinia (Craib and Stapf) is a genus with high economic pharmacological values. Aim: This study aimed at establishing the morphological, anatomical molecular characterisation of leaves I. doka tomentosa, which were conducted for proper authentication. Setting: The tomentosa obtained from Shika, kaduna State, Nigeria. Method: Morphological characters determined according to stand...
جلبک دونالیلا یک ریز جلبک سبز فتوسنتز کننده می باشد که همراه با جذب گاز دی اکسید کربن و تولید اکسیژن، مواد آلی و محصولات شیمیایی مفیدی را تولید می کند.به همین دلیل در دهه های اخیر در صنایع داروسازی و شیمیایی از آن استفاده های متعددی صورت می گیرد. از این رو، شناسایی و طبقه بندی گونه های مختلف آن برای استفاده از توانایی های این جلبک اهمیت فراوانی دارد. با توجه به دقیق بودن روش های طبقه بندی موجود...
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the key enzyme involved in photosynthetic carbon fixation, converting atmospheric CO2 to organic compounds. Form I Rubisco is a cylindrical complex composed of eight large (RbcL) subunits that are capped by four small subunits (RbcS) at the top and four at the bottom. Form I Rubiscos are phylogenetically divided into green- and red-ty...
We present the first national DNA barcode resource that covers the native flowering plants and conifers for the nation of Wales (1143 species). Using the plant DNA barcode markers rbcL and matK, we have assembled 97.7% coverage for rbcL, 90.2% for matK, and a dual-locus barcode for 89.7% of the native Welsh flora. We have sampled multiple individuals for each species, resulting in 3304 rbcL and...
BACKGROUND Heterophyllous aquatic plants show marked phenotypic plasticity. They adapt to environmental changes by producing different leaf types: submerged, floating and terrestrial leaves. By contrast, homophyllous plants produce only submerged leaves and grow entirely underwater. Heterophylly and submerged homophylly evolved under selective pressure modifying the species-specific optima for ...
The cyanobacterial radiation consists of several lineages of phyletically (morphologically and genetically) related organisms. Several of these organisms show a striking resemblance to fossil counterparts. To investigate the molecular mechanisms responsible for stabilizing or homogenizing cyanobacterial characters, we compared the evolutionary rates and phylogenetic origins of the small-subunit...
BACKGROUND Species identification of living organisms by standard DNA sequences has been well-accepted. Consortium for the Barcode of Life (CBOL) recommends chloroplast regions rbcL and matK as the DNA barcodes for the land plants. This study aims to evaluate the feasibility and limitations of rbcL, matK, and 5 other commonly used regions as the DNA barcodes for the medicinal Gentiana and their...
