    Expansion de familles de gènes de la voie de l’éthylène chez le bananier

    20/06/2014

    Les duplications du génome entier sont très répandues chez les plantes. Les gènes ainsi dupliqués sont majoritairement éliminés au cours de l’évolution mais certains sont conservés en plusieurs copies. L’impact des trois duplications du génome entier du bananier sur l’évolution des gènes a été étudié à l’échelle d’une voie biologique, celle de l’éthylène, l’hormone végétale qui fait murir les fruits du bananier.

    The aim of the present study was to perform a genomic analysis of non-specific lipid-transfer proteins (nsLTPs) in coffee. Several nsLTPs-encoding cDNA and gene sequences were cloned from Coffea arabica and Coffea canephora species.

    A Workshop on Crop Ontology and Phenotyping Data Interoperability will be held at CIRAD in Montpellier, France on 31 March-4th April 2014. Only the presentations of the 3rd April will be public (Cirad Campus de Lavalette, amphitheater, J. Alliot) and they will be focused on Phenotyping Data Management and Interoperability. Participants will include members of the Crop Ontology community and members of the GIS BV Thematic Committee “Bioinformatics and Data Management”.

    Two evolutionarily distinct classes of paleopolyploidy

    26/02/2014

    Cette étude porte sur l’évolution des gènes dupliqués après les derniers événements de paléo-polyploïdisation de 8 génomes de plantes (bananier, peuplier, soja, medicago, Arabidopsis, sorgho, brassica et maïs). La paléopolyploïdie fait référence à une duplication complète du génome survenue il y a plusieurs millions d’années. Ces évènements de polyploïdisation sont particulièrement fréquents chez les plantes et jouent un rôle majeur dans l’évolution des génomes.

    Diversity of coffee trees in the Guineo-Congolese region: the role of climatic refuges and domestication

    01/01/2014

    The species Coffea canephora, which produces Robusta coffee, has substantial genetic diversity, which could almost certainly be better exploited in breeding programmes were it characterized better. A team from CIRAD recently analysed that diversity using microsatellite markers. This was the first truly comprehensive genetic study of the species. It confirmed the existence of diversity groups, analysed the relations between them and determined the genetic structure of the species, particularly the role played by refuge zones during the last glacial maximum and the effect of human intervention on its construction. The results are crucial for the management and use of genetic resource collections.
