Ligularia fischeri (Gom-chi) and Ligularia stenocephala (Gon-dal-bi) are popular edible herbs in Korea. L. fischeri is used to treat jaundice, hepatitis, rheumatoid arthritis, and scarlet fever, while L. stenocephala is used to treat anxiety, weakness, and menstrual disorders. The herbal medicinal activities of these two herbs differ, but they are very difficult to distinguish based on their morphologies, especially in their dried forms. In an effort to distinguish these two plant species, we sequenced three barcoding genes in plastids, matK, rbcL, and trnH-psbA. From the analysis of sequence variations, we detected five single nucleotide polymorphisms (SNPs) between two the species. Allele specific (AS)-primers in the SNPs were employed in discrimination of the two species. Of the five AS-primer sets, one primer pair in matK gene showed reproducibly distinguishable PCR amplification between plants of L. fischeri and L. stenocephala. The method is reproducible and efficient, and is the first reported molecular method to discriminate between L. fischeri and L. stenocephala. 相似文献

In this work, we report the whole-genome sequence of Corynebacterium pseudotuberculosis bv. equi strain CIP 52.97 (Collection Institut Pasteur), isolated in 1952 from a case of ulcerative lymphangitis in a Kenyan horse, which has evidently caused significant losses to agribusiness. Therefore, obtaining this genome will allow the detection of important targets for postgenomic studies, with the aim of minimizing problems caused by this microorganism. 相似文献

Transposable elements account for up to 85% of the maize genome and have significant implications in crop-improvement and evolutionary analyses. The Mutator (Mu) transposon superfamily, a class of DNA transposons, comprises the most complex and active elements in the maize genome, suggesting a special role in plant evolution. Here, we designed a set of Mu-specific primers based on terminal invert repeats and used a transposon display (TD) method for genotyping. We analyzed the distribution pattern of Mu insertions in teosinte (wild relative), sorghum (distant relative), and domesticated maize accessions (dent, sweet, and waxy). The MU-TD analysis suggested the presence of high polymorphic insertions among the species and subspecies, indicating the utility of the method in studying genetic variation and species relationships. Furthermore, we analyzed 80 maize recombinant inbred line populations. Mu-TD generated an average of 60% Mu-anchored polymorphic fragments in which insertions appeared to be segregating in significantly high numbers. The amplification profile was highly reproducible, confirming the utility of Mu elements as a new set of TD markers for developing high-density genetic maps. 相似文献

In this work, we report the complete genome sequence of a Corynebacterium pseudotuberculosis PAT10 isolate, collected from a lung abscess in an Argentine sheep in Patagonia, whose pathogen also required an investigation of its pathogenesis. Thus, the analysis of the genome sequence offers a means to better understanding of the molecular and genetic basis of virulence of this bacterium. 相似文献

India is the fifth largest primary energy consumer and fourth largest petroleum consumer after USA, China, and Japan. Despite the global economic crisis, India’s economy is expected to grow at 6 to 8?%/year. There is an extreme dependence on petroleum products with considerable risks and environmental issues. Petroleum-derived transport fuels are of limited availability and contribute to global warming, making renewable biofuel as the best alternative. The focus on biogas and biomass-based energy, such as bioethanol and biohydrogen, will enhance cost-effectiveness and provide an opportunity for the rural community. Among all energy sources, microalgae have received, so far, more attention due to their facile adaptability to grow in the photobioreactors or open ponds, high yields, and multiple applications. Microalgae can produce a substantial amount of triacylglycerols as a storage lipid under photooxidative stress or other adverse environmental conditions. In addition to renewable biofuels, they can provide different types of high-value bioproducts added to their advantages, such as higher photosynthetic efficiency, higher biomass production, and faster growth compared to any other energy crops. The viability of first-generation biofuels production is, however, questionable because of the conflict with food supply. In the future, biofuels should ideally create the environmental, economic, and social benefits to the communities and reflect energy efficiency so as to plan a road map for the industry to produce third-generation biofuels. 相似文献
