The build-up of osmotic stress responses within the growing root apex using kinematics and RNA-sequencing.

Molecular regulation of growth must include spatial and temporal coupling of cell production and cell expansion. The underlying mechanisms, especially under environmental challenge, remain obscure. Spatial patterns of cell processes make the root apex well suited to deciphering stress signaling ...

Synergistic parasite-pathogen interactions mediated by host immunity can drive the collapse of honeybee colonies.

The health of the honeybee and, indirectly, global crop production are threatened by several biotic and abiotic factors, which play a poorly defined role in the induction of widespread colony losses. Recent descriptive studies suggest that colony losses are often ...

The high-quality draft genome of peach (Prunus persica) identifies unique patterns of genetic diversity, domestication and genome evolution.

Rosaceae is the most important fruit-producing clade, and its key commercially relevant genera (Fragaria, Rosa, Rubus and Prunus) show broadly diverse growth habits, fruit types and compact diploid genomes. Peach, a diploid Prunus species, is one of the best genetically ...

Draft genome sequence of Lactobacillus rossiae DSM 15814(T).

The draft genome sequence of Lactobacillus rossiae DSM 15814T (CS1, ATCC BAA-88) was determined by a whole-genome shotgun approach. Reads were assembled to a 2.9-Mb draft version. RAST genome annotation evidenced 2,723 predicted coding sequences. Many carbohydrate, amino acid, and ...

Odorant-binding proteins and olfactory coding in the solitary bee Osmia cornuta.

Solitary bees are major pollinators but their chemical communication system has been poorly studied. We investigated olfactory coding in Osmia cornuta from two perspectives, chemical and biochemical. We identified (E)-geranyl acetone and 2-hexyl-1,3-dioxolane, specifically secreted by females and males, respectively. ...

A RAD-based linkage map of kiwifruit (Actinidia chinensis Pl.) as a tool to improve the genome assembly and to scan the genomic region of the gender determinant for the marker-assisted breeding

Kiwifruit breeding still largely relies on phenotypic observation of cross progeny grown in the field to fruiting maturity, without any selection prior to the juvenility being overcome. Developing markers for the selection of traits of interest would greatly help breeders ...

Identification of tumorigenesis-related mRNAs associated with RNA-binding protein HuR in thyroid cancer cells Oncotarget.

RNA binding proteins (RBPs) play a central role in cell physiology and pathology. Among them, HuR is a nuclear RBP, which shuttles to the cytoplasm to allow its RNA targets processing. HuR over-expression and delocalization are often associated to cell ...

Exome Capture with Heterologous Enrichment in Pig (Sus scrofa) PLoS One.

The discovery of new protein-coding DNA variants related to carcass traits is very important for the Italian pig industry, which requires heavy pigs with higher thickness of subcutaneous fat for Protected Designation of Origin (PDO) productions. Exome capture techniques offer ...

Heterozygous reelin mutations cause autosomal-dominant lateral temporal epilepsy

Autosomal-dominant lateral temporal epilepsy (ADLTE) is a genetic epilepsy syndrome clinically characterized by focal seizures with prominent auditory symptoms. ADLTE is genetically heterogeneous, and mutations in LGI1 account for fewer than 50% of affected families. Here, we report the identification ...

Suggestive linkage of familial mesial temporal lobe epilepsy to chromosome 3q26

PURPOSE: To describe the clinical findings in a family with a benign form of mesial temporal lobe epilepsy and to identify the causative genetic factors. METHODS: All participants were personally interviewed and underwent neurologic examination. The affected subjects underwent EEG ...

The limits and potential of paleogenomic techniques for reconstructing grapevine domestication

In ancient DNA (aDNA) research, evolutionary and archaeological questions are often investigated using the genomic sequences of organelles: mitochondrial and chloroplast DNA. Organellar genomes are found in multiple copies per living cell, increasing their chance of recovery from archaeological samples, ...

CNV and Structural Variation in Plants: Prospects of NGS Approaches

Deletion, insertion, and duplications larger than 1 kb are structural variants (SVs) classified as copy number variants (CNVs). Beside single nucleotide variants (SNVs), CNVs are widespread in plants and substantially contribute to intra-species genetic variation. Most CNVs reported so far ...

Identification, Reconstruction And Validation Of Insertions In Resequencing Projects With GapFiller

Motivations. A difficult problem in resequencing projects is the identification, reconstruction, and validation of inserted regions within an unknown genome, with respect to a reference one. In most organisms, many structural variants are found in highly repetitive regions of the ...

GAM: Genomic Assemblies Merger

Motivations. In the last 3 years more than 20 assemblers have been proposed to tackle the hard task of assembling. Recent evaluation efforts (Assemblathon 1 and GAGE) demonstrated that none of these tools clearly outperforms the others. However, results clearly ...

LTR retrotransposon dynamics in the evolution of the olive (Olea europaea) genome.

Improved knowledge of genome composition, especially of its repetitive component, generates important information for both theoretical and applied research. The olive repetitive component is made up of two main classes of sequences: tandem repeats and retrotransposons (REs). In this study, ...

Sequencing of diverse mandarin, pummelo and orange genomes reveals complex history of admixture during citrus domestication.

Cultivated citrus are selections from, or hybrids of, wild progenitor species whose identities and contributions to citrus domestication remain controversial. Here we sequence and compare citrus genomes--a high-quality reference haploid clementine genome and mandarin, pummelo, sweet-orange and sour-orange genomes--and show ...
