Vigna mungo, V. radiata and V. unguiculata plants sampled in different agronomical-ecological-climatic regions of India are nodulated by Bradyrhizobi…

2009

International audience; Vigna mungo, Vigna radiata and Vigna unguiculata are important legume crops cultivated in India, but little is known about the genetic resources in native rhizobia that nodulate these species. To identify these bacteria, a core collection of 76 slow-growing isolates was built from root nodules of V. mungo, V. radiata and V. unguiculata plants grown at different sites within three agro-ecological-climatic regions of India. The genetic diversity of the bacterial collection was assessed by restriction fragment length polymorphism (RFLP) analysis of PCR-amplified DNA fragments of the 16S–23S rDNA intergenic spacer (IGS) region, and the symbiotic genes nifH and nodC.

Genetic variability of Girgentana goat breed using molecular markers

2014

Assessing genetic diversity of local breeds through the information provided by neutral molecular markers, allows determination of their extinction risk and to design strategies for their management and conservation. The aim of this work was to quantify the levels of genetic variability in Girgentana goat breed using microsatellite markers and genetic polymorphisms at the casein genes. A total of 264 individuals were genotyped for 20 microsatellites, selected as suggested by ISAG and FAO. Moreover, the same individuals were characterized for the casein loci (CSN1S1, CSN2, CSN1S2, and CSN3) using PCR and sequencing protocols. Several genetic diversity indexes were estimated. A total of 130 a…

Genome-wide scan for Runs of Homozygosity in Valle del Belice sheep

2017

The current availability of very large numbers of single nucleotide polymorphisms (SNPs) throughout the genome makes these markers particularly suitable for the detection of genomic regions where a reduction in heterozygosity occurred and offers new opportunities to improve the accuracy of inbreeding (F) estimates. Runs of homozygosity (ROH) are contiguous lengths of homozygous segments of the genome where the two haplotypes inherited from the parents are identical. Here, we investigated the occurrence and the distribution of ROH in medium-density SNP genotypes (~ 50 000) in order to characterize autozygosity in 512 individuals of Valle del Belice sheep and identify the regions of the genom…

Distribution of functional variants within Runs of Homozygosity in four Italian cattle breeds

2017

Several methods have been used to identify genomic regions subjected to selective sweeps. An alternative method can make use of runs of homozygosity (ROH), defined as stretches of homozygous regions in a genome. The aim of the present study was to detect selective sweeps using ROH in four cattle breeds. Individuals of Cinisara (71), Modicana (72),Reggiana (168) and Italian Holstein (96) were genotyped with the Illumina Bovine50SNP v2 BeadChip. To identify genomic regions that were most commonly associated with ROH within each breed, the percentage of occurrences of a single nucleotide polymorphism (SNP) in ROH was calculated across animals. The genomic regions most commonly associated with …

Weighted Single-Step Genome-Wide Association Study Uncovers Known and Novel Candidate Genomic Regions for Milk Production Traits and Somatic Cell Sco…

2022

The objective of this study was to uncover genomic regions explaining a substantial proportion of the genetic variance in milk production traits and somatic cell score in a Valle del Belice dairy sheep. Weighted single-step genome-wide association studies (WssGWAS) were conducted for milk yield (MY), fat yield (FY), fat percentage (FAT%), protein yield (PY), protein percentage (PROT%), and somatic cell score (SCS). In addition, our aim was also to identify candidate genes within genomic regions that explained the highest proportions of genetic variance. Overall, the full pedigree consists of 5534 animals, of which 1813 ewes had milk data (15,008 records), and 481 ewes were genotyped with a …

Enhancer, chromatin insulator, non-coding RNA and α-histone gene expression during embryogenesis of the sea urchin Paracentrotus lividus.

2009

Core promoters and chromatin insulators (ins) may direct a transcriptional enhancer (enh) to prefer a specific promoter in complex genetic loci. Enh and ins flank the sea urchin Paracentrotus lividus α-histone H2A transcription unit in a tandem repeated cluster containing the five histone genes. In vivo competition assays of enh and ins functions reveal that the H2A enh-bound MBF-1 activator participates also in the expression of the H3 gene and that the sns5 ins buffers the downstream H1 promoter from the H2A enh. These results suggest that both the H2A enh and the sns5 ins may account for the diverse accumulation of the linker vs core nucleosomal histones during early development of the s…

Stato, rivoluzione e violenza simbolica. Una lettura à la Bourdieu dell’insorgenza cilena

2023

The essay is part of a book that aims to rediscover and enhance Pierre Bourdieu's contribution to the legal philosophy. Clelia Bartoli's paper takes up the French sociologist's theory of the State outlined during courses held at the College de France in 1989/1990 and 1990/1992. Bourdieu eschewed an intellectual fashion of his time that pushed historians, political scientists, lawyers and sociologists to examine the causes and reasons, evolutions and epilogues of revolutions, at the expense, however, of what is happening on the background: the dull, muffled and repetitive order of things. Bourdieu believed that permanence more than change, what is obvious more than what is eccentric, the ord…

Settore IUS/20 - Filosofia Del DirittoSettore SPS/11 - Sociologia Dei Fenomeni PoliticiSettore SPS/01 - Filosofia PoliticaIl saggio si inserisce in un volume che intende riscoprire e valorizzare il contributo di Pierre Bourdieu alla filosofia del diritto. Lo scritto di Clelia Bartoli riprende soprattutto la teoria dello Stato del sociologo francese delineata durante i corsi tenuti al College de France nel 1989/1990 e nel 1990/1992. Bourdieu ha rifuggito una moda intellettuale a lui coeva che spingeva storici politologi giuristi e sociologi a vagliarne cause e ragioni evoluzioni ed epiloghi delle rivoluzioni a discapito però di quanto accade sul fondale: lo scialbo ovattato e ripetitivo ordine delle cose. Bourdieu riteneva che dovesse stupire e meritare di essere spiegato fosse più la permanenza del mutamento l’ovvio più dell’eccentrico l’ordinario più straordinario. Tuttavia nel corso delle lezioni menzionate afferma che per provare nell’ardua impresa di pensare e comprendere lo Stato sia necessario guardare al momento della sua genesi o alle fasi di crisi come durante le rivoluzioni. È infatti in quei momenti che il potere simbolico di cui lo Stato ha il monopolio non è stabile e si presta ad essere osservato come frutto di un processo anziché nella sua ineluttabilità. Le categorie e l’approccio socioepistemico à la Bourdieu vengono adottate dalla Bartoli per leggere il caso dell’insorgenza cilena del 2019 e l’esordio del processo costituente.

TGF-β/VEGF-A Genetic Variants Interplay in Genetic Susceptibility to Non-Melanocytic Skin Cancer

2022

Differential genetically determined expression of transforming growth factor-β (TGF-β pathway and of vascular endothelial growth factor-A (VEGF-A) might modulate the molecular “milieu” involved in the etio-pathogenesis of non-melanoma skin cancer (NMSC). We have evaluated the frequency of some functionally relevant SNPs of TGF-β and VEGF-A genes in 70 NMSC patients and 161 healthy controls, typed for TGF-β1 rs1800471, TGF-β2 rs900, TGF-βR1 rs334348 and rs334349, TGF-βR2 rs4522809 and VEGF-A rs3025039 SNPs. TGF-βR2 rs1800629G allele and related genotypes were found to be associated with a possible protective role against NMSC, whereas VEGF-…
