Seven races of Striga gesnerioides parasitic on cowpea, a major food and forage legume in sub-Saharan Africa, have been identified. Race-specific resistance of cowpea to Striga involves a coiled-coil nucleotide binding site leucine-rich repeat domain resistance protein encoded by the RSG3-301 gene. Knockdown of RSG3-301 expression by virus-induced gene(More)
BACKGROUND Human infections with different avian influenza viruses--eg, H5N1, H9N2, and H7N9--have raised concerns about pandemic potential worldwide. We report the first human infection with a novel reassortant avian influenza A H10N8 virus. METHODS We obtained and analysed clinical, epidemiological, and virological data from a patient from Nanchang(More)
In order to increase the speed of genetic watermarking and improve the robustness and imperceptibleness of the algorithm, a new embedding and extracting method with genetic algorithm (GA) was proposed. The AC coefficients of image in DCT domain were modified to embed the watermark. The proposed embedding and extracting method was employed to accelerate the(More)
On a local scale, invasiveness of introduced species and invasibility of habitats together determine invasion success. A key issue in invasion ecology has been how to quantify the contribution of species invasiveness and habitat invasibility separately. Conventional approaches, such as comparing the differences in traits and/or impacts of species between(More)
Transcriptional networks orchestrate complex developmental processes, and such networks are commonly instigated by master regulators for development. By now, considerable progress has been made in elucidating GATA factor-dependent genetic networks that control red blood cell development. Here we reported that GATA-1 and GATA-2 co-regulated the expression of(More)
BACKGROUND MicroRNAs act as posttranscriptional regulators of gene expression in many biological processes. Their deregulations occur commonly in gastric cancer (GC). Although DNA methylation constitutes an important mechanism for microRNA deregulation in cancer, this field largely remains unexplored. METHODOLOGY/PRINCIPAL FINDINGS Total RNA was extracted(More)
Type B influenza virus is one of the major epidemic strains and responsible for considerable mortality and morbidity. Rapidly and accurately identifying different influenza B virus lineages, i.e., B/Yamagata (B/Y) and B/Victoria (B/V), is desirable during the flu season. However, the available rapid techniques lack sensitivity, and the usual methods for(More)
Heterosis is a commonly observed phenomenon in nature and refers to the superior performance of hybrids relative to both parents. The molecular mechanisms of heterosis are mostly unknown. Quantitative trait locus (QTL) mapping has been used to explain the genetic basis of heterosis, and large amounts of QTLs have been mapped for various agronomic traits,(More)
Vehicle detection technology is the key technology of intelligent transportation systems, attracting the attention of many researchers. Although much literature has been published concerning daytime vehicle detection, little has been published concerning nighttime vehicle detection. In this study, a nighttime vehicle detection algorithm, consisting of(More)
