Sex determination (SD) shows huge variation among fish and a high evolutionary rate, as illustrated by the Pleuronectiformes (flatfishes). This order is characterized its adaptation to demersal life, compact genomes diversity of SD mechanisms. Here, we assembled Solea senegalensis genome, flatfish great commercial value, into 82 contigs (614 Mb) combining long- short-read sequencing, which were next scaffolded using highly dense genetic map (28,838 markers, 21 linkage groups), representing...
The genus Rumex includes hermaphroditic, polygamous, gynodioecious, monoecious, and dioecious species, with the species being represented by different sex-determining mechanisms sex-chromosome systems. Therefore, this represents an exceptional case study to test several hypotheses concerning evolution of both mating systems genetic control sex determination in plants. Here, we compare nuclear intergenic transcribed spacers chloroplast sequences 31 Rumex. Our phylogenetic analysis supports a...
Five Gram-negative bacterial isolates, recovered from an outbreak that occurred in March 2006 Huelva, Spain, affecting adult diseased cultured wedge sole [ Dicologlossa cuneata (Moreau)], were characterized phenotypically and genotypically order to clarify their taxonomic position. On the basis of 16S rRNA gene sequence analysis, isolates included genus Pseudomonas , within fluorescens -related species group, closest relatives being jessenii koreensis subgroups. The highest similarities...
Abstract Endopolyploidy is a well-documented phenomenon in the natural world, yet its biological significance remains poorly understood. A multitude of effects and consequences have been described literature as being attributable to this phenomenon, none them subjected rigorous well-established confirmation. The measurement ploidy level typically conducted using flow cytometry or densitometry techniques. Conversely, direct chromosome counting less frequently employed method. As result, all...
Pistachio is a nut crop domesticated in the Fertile Crescent and dioecious species with ZW sex chromosomes. We sequenced genomes of Pistacia vera cultivar (cv.) Siirt, female parent, P. cv. Bagyolu, male parent. Two chromosome-level reference pistachio were generated, Z W chromosomes assembled. The originated from an autosome following first inversion, which occurred approximately 8.18 Mya. Three inversion events chromosome led to formation 12.7-Mb (22.8% chromosome) non-recombining region....
Marteilia refringens is a paramyxean parasite which infects the flat oyster Ostrea edulis and mussels (Mytilus galloprovincialis), where it has been attributed to separate species, maurini, by several authors. Doubts persist though as existence or not of two species in Europe. We have devised molecular method for diagnosis M. based on 358 bp nested-PCR rDNA intergene spacer (rDNA IGS) capable detecting 0·5 fg DNA. Molecular characterization this indicates that parasites infect oysters are...
Abstract Background The turbot ( Scophthalmus maximus ) is a relevant species in European aquaculture. small genome provides source for genomics strategies to use order understand the genetic basis of productive traits, particularly those related sex, growth and pathogen resistance. Genetic maps represent essential genomic screening tools allowing localize quantitative trait loci (QTL) identify candidate genes through comparative mapping. This information backbone develop marker-assisted...
Ribosomal DNA in sturgeon is informative when analyzed at the molecular level because it bears unique characteristics that are, to a certain extent, ancestral within vertebrates. In this paper, we examine structure and evolution of 5S ribosomal (rDNA) region 13 species, comparing both RNA (rRNA) genes non-transcribed spacer (NTS) sequences between coding regions. We have found different NTS gene variants are intermixed rDNA arrays species all ancestral, having been maintained over many...
This paper reports on the isolation and localization of subtelomeric <i>Dra</i>I satellite DNA in Sparidae family. Gene cloning determined that is present only 3 species (<i>Pagrus pagrus, P. auriga,</i> <i>Pagellus erythrinus</i>) 10 analyzed. The results were confirmed by PCR amplification. located a position all 48 acrocentric chromosomes these species. However, interstitial loci are also observed. Sequence analysis monomers this repetitive family...
Rumex acetosa is characterized by a multiple chromosome system (2n = 12 + XX for females, and 2n XY 1 Y 2 males), in which sex determined the ratio between number of X chromosomes autosome sets. For better understanding molecular structure evolution plant chromosomes, we have generated specific library R. microdissection. The screening this has allowed us to identify 5 repetitive DNA families that been detail. One these families, DOP-20, shown no homology with other sequences databases....
