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)
An earlier reported method for revealing latent periodicity of the nucleotide sequences has been considerably modified in a case of small samples, by applying a Monte Carlo method. This improved method has been used to search for the latent periodicity of some nucleotide sequences of the EMBL data bank. The existence of the nucleotide sequences' latent(More)
Four full-length MADS-box cDNAs from chrysanthemum, designated Chrysanthemum Dendrathema grandiflorum MADS (CDM) 8, CDM41, CDM111, and CDM44, have been isolated and further functionally characterized. Protein sequence alignment and expression patterns of the corresponding genes suggest that CDM8 and CDM41 belong to the FRUITFULL (FUL) clade, CDM111 is a(More)
Thermoproteus uzoniensis 768-20 is a thermoacidophilic anaerobic crenarchaeon isolated from a solfataric field in Kamchatka, Russia. The complete genome sequence reveals genes for protein and carbohydrate-active enzymes, beta-oxidation of fatty acids, the Embden-Meyerhof and Entner-Doudoroff pathways for glucose metabolism, the tricarboxylic acid cycle, the(More)
The nucleotide sequences of genomic RNAs and predicted amino acid sequences of two strains of potato virus X and white clover mosaic potexvirus were compared to each other, and the proteins of different plus-RNA-containing plant viruses. The predicted non-virion proteins of potexviruses have direct sequence homology and common structural peculiarities with(More)
In plant pararetroviruses, pregenomic RNA (pgRNA) directs synthesis of circular double-stranded viral DNA and serves as a polycistronic mRNA. By computer-aided analysis, the 14 plant pararetroviruses sequenced so far were compared with respect to structural organization of their pgRNA 5'-leader. The results revealed that the pgRNA of all these viruses(More)
Desulfurococcus kamchatkensis is an anaerobic organotrophic hyperthermophilic crenarchaeon isolated from a terrestrial hot spring. Its genome consists of a single circular chromosome of 1,365,223 bp with no extrachromosomal elements. A total of 1,474 protein-encoding genes were annotated, among which 205 are exclusive for D. kamchatkensis. The search for a(More)
Mouse genome contains two major families of short interspersed repeats in more than 10(5) copies scattered throughout the whole genome. They are referred to as B1 and B2 sequences since they were first isolated from the genome library by means of a dsRNA-B probe /1/. In this work, two copies of the B2 family were sequenced and compared with the previously(More)
The expression and assembly of the hepatitis B virus (HBV) nucleocapsid protein (HBcAg) were investigated in plants using viral vectors. Constructs based on either Potato virus X (PVX) or Cowpea mosaic virus (CPMV) containing the sequence of HBcAg were able to infect the appropriate host plants and remained genetically stable during infection. Analysis of(More)
