The walnut genetic resources of INRA: chronological phenotypic data and ontology.
OBJECTIVES: Persian walnut (Juglans regia L.), the walnut species cultivated for nut production, is grown worldwide in temperate areas. In this work, chronological phenotypic data have been collected regarding a part of the walnut genetic resources of the French National Institute for Agricultural Research (INRA) of Bordeaux. Using a well described ontology, these data have […]
Conserved DNA-derived polymorphism, new markers for genetic diversity analysis of Tunisian Pistacia vera L.
Pistachio trees (Pistacia vera L.) have been cultivated in Tunisia for decades and the plantation was extended mostly in the center of the country contributing to the economic growth of marginalized areas. Herein we used conserved DNA derived polymorphism (CDDP) technique, which target specifically conserved sequences of plant functional genes, to assess the genetic diversity and construct […]
Complete Genome Sequences of Four Salmonella enterica Strains Associated with Pistachios Assembled Using a Combination of Short-and Long-Read Sequencing.
Here, we report the genomes of two Salmonella enterica subsp. enterica serovar Montevideo strains (CFSAN005645 and FCC0123) and two Salmonella enterica subsp. enterica serovar Senftenberg strains (FSW0104 and CFSAN087304) isolated from pistachios. The genomes were closed using a hybrid assembly method using short- and long-read sequencing technology.
Transposons played a major role in the diversification between the closely related almond and peach genomes: Results from the almond genome sequence.
We sequenced the genome of the highly heterozygous almond Prunus dulcis cv. Texas combining short and long-read sequencing. We obtained a genome assembly totaling 227.6 Mb of the estimated 238 Mb almond genome size, of which 91% is anchored to eight pseudomolecules corresponding to its haploid chromosome complement, and annotated 27,969 protein-coding genes and 6,747 non-coding transcripts. […]
Marker-assisted backcrossing to improve seed oleic acid content in four elite and popular peanut (Arachis hypogaea L.) cultivars with high oil content.
High oleic acid composition is an important determinant of seed quality in peanut (Arachis hypogaea) in regard to its nutritional benefits for human health and prolonged shelf-life for peanut products. To improve the oleic acid content of popular peanut cultivars in China, four peanut cultivars of different market types were hybridized with high-oleic-acid donors and backcrossed […]
Adipocyte metabolism is improved by TNF receptor-targeting small RNAs identified from dried nuts.
There is a growing interest in therapeutically targeting the inflammatory response that underlies age-related chronic diseases including obesity and type 2 diabetes. Through integrative small RNA sequencing, we show the presence of conserved plant miR159a and miR156c in dried nuts having high complementarity with the mammalian TNF receptor superfamily member 1a (Tnfrsf1a) transcript. We detected […]
Genetic diversity and structure in the northern populations of European hazelnut (Corylus avellana L.).
European hazelnut (Corylus avellana L.) is a strictly cross-pollinated diploid tree species, which has its northernmost populations in Fennoscandia, and it was one of the first species to recolonize northern Europe after the last ice age. Hazelnut produces edible nuts in Finland but nowadays they are underutilized as food, and currently no breeding programmes exist. In the present study, 300 […]
Mutation of a bHLH transcription factor allowed almond domestication
Wild almond species accumulate the bitter and toxic cyanogenic diglucoside amygdalin. Almonddomestication was enabled by the selection of genotypes harboring sweet kernels. We report the completion of the almond reference genome. Map-based cloning using an F1 population segregating for kernel taste led to the identification of a 46-kilobase gene cluster encoding five basic helix-loop-helix transcription factors, bHLH1 to bHLH5. Functional characterization demonstrated that bHLH2 […]
Brazil nut intake increases circulating miR-454-3p and miR-584-5p in obese women.
The Brazil nut is an excellent source of selenium (Se), an essential micronutrient for human health. In this study, we hypothesized that Brazil nut intake modulates circulating microRNAs (miRNAs) in obese women and aimed to evaluate the effects of this nut intake on circulating miRNAs in women with obesity or metabolic syndrome (MetS). A randomized […]
Pistachio consumption modulates DNA oxidation and genes related to telomere maintenance: a crossover randomized clinical trial.
BACKGROUND: Telomere attrition may play an important role in the pathogenesis and severity of type 2 diabetes (T2D), increasing the probability of β cell senescence and leading to reduced cell mass and decreased insulin secretion. Nutrition and lifestyle are known factors modulating the aging process and insulin resistance/secretion, determining the risk of T2D. OBJECTIVES: The […]
