The potato genome sequence derived from the Solanum tuberosum Group Phureja clone DM1-3 516 R44 provides unparalleled insight into the genome composition and organisation of this important crop. A key class of genes that comprises the vast majority of plant resistance (R) genes contains a nucleotide-binding and leucine-rich repeat domain, and is(More)
Potato (Solanum tuberosum L.) is the world's most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031(More)
The genome of potato, a major global food crop, was recently sequenced. The work presented here details the integration of the potato reference genome (DM) with a new sequence-tagged site marker-based linkage map and other physical and genetic maps of potato and the closely related species tomato. Primary anchoring of the DM genome assembly was accomplished(More)
Inactive carriers forms the largest group in chronic HBV infected patients. Around 300 million people are inactive carriers The inactive HBsAg carrier state is diagnosed by absence of HBeAg and presence of anti-HBe, undetectable or low levels of HBV DNA in PCR-based assays, repeatedly normal ALT levels, and minimal or no necroinflammation, slight fibrosis,(More)
Generation of a dense SNP-based linkage map of a diploid potato population and identification of major QTLs for tuber shape and eye depth on chromosomes 2 and 10. This paper reports the construction of a genetic map of a highly heterozygous full-sib diploid potato population (06H1) based on the use of a set of 8,303 single nucleotide polymorphism (SNP)(More)
Today's power consumption is the critical issue in MANET. Since, we have limited battery power to operate nodes. Due to the lack of power (Energy), the nodes " die out " from the network. Recently, power control in mobile ad hoc networks has been the focus of extensive research. Energy of nodes is consumed according to transmission power required by the(More)
For most organisms, even if their genome sequence is available, little functional information about individual genes or proteins exists. Several annotation pipelines have been developed for functional analysis based on sequence, ‘omics’, and literature data. However, researchers encounter little guidance on how well they perform. Here, we used the recently(More)
The late blight disease can be managed by introduction of resistance (R) genes from the wild Solanum species into the cultivated potato. The R genes are mostly comprised of the nucleotide binding site-leucine rich repeat (NBS-LRR) domains and share nucleotide sequence homology in the crop species. In this study, we used potato R gene-specific primers to(More)
Bacterial wilt or brown rot is one of the most devastating diseases of potato caused by a bacterium Ralstonia solanacearum (Smith 1986) Yabuuchi et al. (Microbiol Immunol 39:897–904 1995). Traditionally, R. solanacearum is classified into five races (r) on the basis of differences in host range and six biovars (bvs) on the basis of biochemical properties.(More)
