Description : Loss of agrodiversity mediated by varietal legacy is an important concern, translating as crop species being at risk for genetic erosion, while loss of genetic resources may deplete material available for future breeding strategies. We explored varietal dynamics in the Guadeloupean agricultural yam system. Interviewing farmers about the varieties cultivated in the past compared to their current varieties demonstrated that no dramatic loss of varieties occurred in the two to three latest decades, and changes in variety frequency mostly affected former widespread varieties while frequency of uncommon varieties demonstrated some stability in cultivation frequency. Varietal dynamics nevertheless reflected strong sub-regional trends, and socio-economic impacts such as age of producers or in farm crop diversity. Recurrent epidemics of anthracnose since its historical start in the 70s did not change varietal turnover too strongly, but resulted into transition from Dioscorea alata to less susceptible species or into a decrease of yam cultivation especially for farmers with financial dissatisfaction. La perte d'agrodiversité négociée par le legs variétal est un souci important, traduisant comme espèces de culture étant en danger pour l'érosion génétique, alors que la disparition des ressources génétiques peut épuiser le matériel disponible pour de futures stratégies d'élevage. Nous avons exploré la dynamique variétale dans le système agricole d'igname en Guadeloupe. Les agriculteurs enquêtés au sujet des variétés cultivées dans le passé comparé à leurs variétés actuelles ont démontré qu'aucune perte dramatique de variétés ne s'est produite pendant les deux à trois dernières décennies, et les changements de la fréquence de variété ont en grande partie affecté d'anciennes variétés répandues tandis que la fréquence des variétés rares démontrait une certaine stabilité dans la fréquence de culture. La dynamique variétale a néanmoins reflété des tendances sous-régionales fortes, et les impacts socio-économiques tels que l'âge des producteurs ou dans la ferme cultivent la diversité. Épidémies récurrentes d'anthracnose puisque son début historique pendant les années 70 n'a pas changé le chiffre d'affaires variétal trop fortement, mais résulté dans la transition de dioscorea alata aux espèces moins susceptibles ou dans une diminution de culture d'igname particulièrement pour des agriculteurs avec mécontentement financier.

Description : Breeding new interspecific banana hybrid varieties with pests and disease resistance characters is instrumental for the development of pesticide-free agroecological banana farming systems. Such breeding relies on the combined use of Musa acuminata and M. balbisiana parents. Unfortunately, infectious alleles of endogenous Banana streak virus (eBSV) sequences are present in the genome of M. balbisiana genitors. Upon activation by biotic and abiotic stresses, these infectious eBSVs lead to spontaneous infections by several species of Banana streak virus (BSV) in interspecific hybrids harbouring both M. acuminata and M. balbisiana genomes. In this work, we show that M. balbisiana diploid genitors available for breeding host at least one infectious eBSV. We also show how we segregated infectious and non-infectious eBSV alleles in seedy M. balbisiana diploids through self- pollination or chromosome doubling of haploid lines. We report on the successful breeding of M. balbisiana diploid genitors devoid of all infectious eBSV alleles following self-pollination and on the potential of breeding additional M. balbisiana diploid genitors free of infectious eBSVs by crossing parents displaying complementary eBSV patterns. This work paves the way to the safe use of M. balbisiana genitors for breeding banana interspecific hybrid varieties with no risk of activation of infectious eBSVs.

Description : Drosophila often offers many advantages as an experimental organism. The dead ringer (dri) gene of drosophila melanogaster is a member of the recently discovered ARID-box family of eukaryotic genes that encodes proteins with a conserved DNA-binding domain. dri itself is highly well conserved with specific orthologs from human to yeast genomes. This family include ARID3A, 3B and 3C with have role in embryonic pattening, cell lineage gene regulation, cell cycle control, transcriptional regulation and chromatin structure modification. We first showed that the gene encoding ARID3A also known as Bright (B cell regulator of immunoglobulin heavy chain transcription) play critical roles in B-cell development and SATB1 in T-cell transcription regulation. In this international workshops we will expose a comprehensive understanding of these molecules and better knowledge of their specific targets and function-interactions in controlling cell fate decisions and development. In addition, dri have homology with the Aedes aegypti mosquitoes which had ability to carry and spread disease to human. More than half of the world?s population live in areas where this mosquito species is present, including Martinique. Sustained mosquito control efforts are important to prevent outbreaks from Dengue, Chikungunya, malaria, zika diseases. Discovering the functions of AT-rich genes in preventing illness from mosquito is the central goal for raising working progress hypothesis.

Description : Chlordecone is a persistent organochlorine pesticide widely used between 1972 and 1993 in the French West Indies to control the root borer in banana fields. Chlordecone use resulted in long-term pollution of soils, contamination of waters, of aquatic organisms, and of fields. Chlordecone is known to be neurotoxic, to increase prostate cancer, and to have negative effects on cognitive and motor development during infancy. In Guadeloupe, most of the freshwater species living in contaminated rivers exceed the French legal limit of 20 ?g·kg?1 wet weight. In the present study (ANR MACHLOMA), we chose a transcriptomic approach to study the cellular effects of chlordecone in the giant freshwater prawn Macrobrachium rosenbergii, an important economical species in Guadeloupe.

Résumé : The slides were taken on collecting trips sponsored by the William L. Bryant Foundation, where books, music and art indigenous to the regions were gathered. The are organized by geographical location.
People walking down Bamboo Avenue in Lacovia, Saint Elizabeth, Jamaica. Bamboo Avenue, also known as “Bamboo Walk”, is a highway approximately 2.5 miles long planted with bamboos forming an arched canopy over the road. It is also known as Holland Bamboo because it was planted by the owners of the Holland Estate, a sugar estate that dates back to the mid-1700s. The avenue was planted with the Bambusa Vulgaris a species of Bamboo which was the largest variety introduced in Jamaica. Slide labeled Bamboo over road on Southern Plains.

Résumé : This small, Greek Revival memorial borders the east side of the Plaza de Armas. It commemorates the city's first Catholic mass and town council meeting, which took place on the site in 1519. The temple was built in 1828. The first mass took place under a silk-cotton tree, so a tree of this species shades El Templete. Once or twice each century, the tree grows too large for the site, and is replaced.
