A la recherche de l'huître portuguaise: identification de marqueurs moléculaires discriminant Crassostrea angulata et Crassostrea gigas ArchiMer
Cornette, Florence.
L'étude historique de l'ostréiculture française monte que cette activité est caractérisée par des périodes de prospérités et de pénurie. Des épizooties ont été à l'origine de ces alternances. A chacune de ces période, on a pu constater des changements d'espèces : Ostrea edulis fut remplacée par Crassostrea angulata, de même celle-ci fut remplacée par Crassostrea gigas dans les années 1970. L'étude de la bibliographie montre que les techniques utilisées pour distinguer des espèces Crassostrea angulata et Crassostrea gigas sont insuffisantes. L'évolution des technologies en matière d'analyses génétiques ouvrent de nouvelles perspectives. La recherche de marqueurs moléculaires réalisée sur Crassostrea angulata et Crassostrea gigas, par amplification par PCR...

An insight into the linkage disequilibrium map of the Canchim beef cattle breed. Repositório Alice
MOKRY, F. B.; LIMA, A. O. de; MUDADU, M. A.; HIGA, R. H.; MEIRELLES, S. L. C.; REGITANO, L. C. de A..
The development of linkage disequilibrium (LD) maps is very important for understanding the nature of non-linear association between phenotypes and genes, as LD can be defined as the non-random segregation of a pair of alleles at polymorphic sites. Canchim is a composite beef cattle breed which was developed in the 1960's by the crossing of Bos indicus (3/8) x Charolais (5/8) animals. The objective in this study was to analyze the extension of LD maps from a Canchim beef cattle population.

Differential fine-tuning of gene expression regulation in coffee leaves by CcDREB1D promoter haplotypes under water deficit. Repositório Alice
ALVES, G. S. C.; TORRES, L. F.; DÉCHAMP, E.; BREITLER, J-C.; JOËT, T.; GATINEAU, F.; ANDRADE, A. C.; BERTRAND, B.; MARRACCINI, P.; ETIENNE, H..
Despite the importance of the DREB1D gene (also known as CBF4) in plant responses to water deficit and cold stress, studies analysing its regulation by transgenic approaches are lacking. In the current work, a functional study of three CcDREB1D promoter haplotypes (named HP15, HP16 and HP17) isolated from drought-tolerant and droughtsensitive clones of Coffea canephora was carried out in plants of C. arabica stably transformed by Agrobacterium tumefaciens by analysing their ability to regulate the expression of the uidA reporter gene in response to water deficit mimicked by polyethylene glycol (−2.0 MPa) and low relative humidity treatments.

Evaluating methodologies for species delimitation: the mismatch between phenotypes and genotypes in lichenized fungi (Bryoria sect. Implexae, Parmeliaceae) Naturalis
Boluda, C.G.; Rico, V.J.; Divakar, P.K.; Nadyeina, O.; Myllys, L.; McMullin, R.T.; Zamora, J.C.; Scheidegger, C.; Hawksworth, D.L..
In many lichen-forming fungi, molecular phylogenetic analyses lead to the discovery of cryptic species within traditional morphospecies. However, in some cases, molecular sequence data also questions the separation of phenotypically characterised species. Here we apply an integrative taxonomy approach ‒ including morphological, chemical, molecular, and distributional characters ‒ to re-assess species boundaries in a traditionally speciose group of hair lichens, Bryoria sect. Implexae. We sampled multilocus sequence and microsatellite data from 142 specimens from a broad intercontinental distribution. Molecular data included DNA sequences of the standard fungal markers ITS, IGS, GAPDH, two newly tested loci (FRBi15 and FRBi16), and SSR frequencies from 18...

Occurrence of 15 haplotypes of linepithema micans (Hymenoptera: Formicidae) in southern Brazil. Repositório Alice
RAMALHO, M. O.; MARTINS, C.; CAMPOS, T.; NONDILLO, A.; BOTTON, M.; BUENO, O. C..
Abstract The ant genus Linepithema is widely known, thanks to the pest species Linepithema humile (Mayr), which is easily mistaken for Linepithema micans (Forel) due to their morphological similarity. Like L. humile , L. micans is associated to the main grapevine pest in Brazil, Eurhizococcus brasiliensis (Wille), also known as ground pearl. Therefore, the present study uses mtDNA fragments to expand the knowledge of haplotype diversity and distri- bution of L. micans in the state of Rio Grande do Sul Brazil), to understand the genetic differences of the popu- lations identified in this study. We identified 15 haplotypes of L. micans spread across different localities. Twelve of these haplotypes were new for the species. The high haplotype diversity...

Populations analysis of the Brazilian Sharpnose Shark Rhizoprionodon lalandii (Chondrichthyes: Carcharhinidae) on the São Paulo coast, Southern Brazil: inferences from mt DNA sequences Neotropical Ichthyology
Mendonça,Fernando Fernandes; Oliveira,Claudio; Gadig,Otto Bismarck Fazzano; Foresti,Fausto.
Sharks of the genus Rhizoprionodon can be considered some of the most important predators along the trophic coastal marine ecosystems and represent an important economic resource for the small-scale fisheries, especially on the Brazilian coastline. In order to analyze the population structure of the shark Rhizoprionodon lalandii of São Paulo, Southeastern coast of Brazil, levels of genetic diversity were identified by nucleotide sequence analyses of the mitochondrial DNA control region. The results obtained from this study present moderate values of haplotype diversity and low nucleotide diversity. Although the AMOVA tests (ΦST = 0.08394, P < 0.01) had shown slightly differences among the studied samples, evidence for the occurrence of population...

PRUNE2 gene has a potential effect on residual feed intake in Nellore cattle. Repositório Alice
LIMA, A. O. D.; OLIVEIRA, P. S. N.; TIZIOTO, P. C.; SOMAVILLA, A. L.; DINIZ, W. J. S.; SILVA, J. V. D.; ANDRADE, S. C. S.; BOSCHIERO, C.; CESAR, A. S. M.; SOUZA, M. M.; ROCHA, M. I. P.; AFONSO, J.; BUSS, C. E.; MUDADU, M. de A.; MOURAO, G. B.; COUTINHO, L. L.; REGITANO, L. C. de A..
Residual feed intake (RFI) can increase the profitability of producers, reduce methane emission and land allocation to livestock production. However, this trait has late and costly measurements. Identifying gene expression changes combined with polymorphisms that affect residual feed intake variation is important for identify target regulatory polymorphisms that can be used in animal breeding programs. Diverse studies performed by our research group in a Nellore population, such as genome-wide association (GWA), association weight matrix (AWM) and RNA-seq analysis of liver tissue have been pointed Prune homolog 2 (Drosophila) (PRUNE2) as a potential candidate gene influencing feed efficiency. For this reason, we select this gene for a more detailed...

Revealing fine scale subpopulations structure in the Vietnamese H'mong cattle breed for conservation purposes Inra
Berthouly, C.; Maillard, J.C.; Pham Doan, L.; Nhu Van, T;; Bed'Hom, B.; Leroy, G.; Hoang Thanh, H.; Laloë, D.; Bruneau, N.; Vu Chi, C.; Nguyen Dang, V.; Verrier, E.; Rognon, X..
Background: During the last decades, there has been an acceleration of the loss of domestic animal biodiversity. Forconservation purposes, the genetic diversity of the H'Mong cattle, an indigenous local breed was studied. Singlenucleotidepolymorphisms (SNP) of the SRY gene and mtDNA D-Loop sequence were analysed to clarify the origin ofthe breed. The genetic diversity was assessed through genetic data with twenty-five FAO microsatellites, andmorphometric data with five body measurements from 408 animals sampled from eight districts of the Ha Giangprovince.Results: The SRY genes were all of the zebu type. Among the 27 mtDNA haplotypes, 12 haplotypes were of the taurinetype and the remaining 15 of the zebu type. This indicates female taurine introgression in...

Single nucleotide polymorphisms in partial sequences of the gene encoding the large sub-units of ADP-glucose pyrophosphorylase within a representative collection of 10 Musa genotypes Electron. J. Biotechnol.
Mahendhiran,Muhilan; Ramirez-Prado,Jorge Humberto; Escobedo-Gracia Medrano,Rosa Maria; Canto-Canché,Blondy; Tzec-Simá,Miguel; Grijalva-Arango,Rosa; James-Kay,Andrew.
Background ADP-glucose pyrophosphorylase (AGPase) is a rate-limiting enzyme catalyzing the first step in the starch biosynthesis pathway in higher plants. To date, there are no reported variants or isoforms of the AGPase enzyme in bananas (Musa spp. family Musaceae) as is the case of other plants. In this study, genomic DNA sequences homologous to the gene encoding one of the large subunits of the enzyme were amplified from 10 accessions of the genus Musa, including representatives of wild ancestors (AA and BB genomes), dessert bananas (AA, AAA, AB and AAB genomes), plantains (AAB genome) and cooking bananas (ABB and AAA genomes), and studied in order to find single nucleotide polymorphisms (SNP) base variations in Musa accessions. Results In the 810-base...
