Plant genes involved in arbuscular mycorrhiza formation and functioning
Knowledge about that part of the plant genome involved in the establishment and functioning of the arbuscular mycorrhizal (AM) symbiosis is important for the basic understanding of this symbiosis. It is also essential for a ‘genes to the field’ approach based on the identification and exploitation of genes that could be central to developing sustainable plant production systems in the future.
Raspberry breeding and biotisation for increasing plant stress tolerance and antioxidant activity
International audience; Chemical inputs used in red fruit production can be detrimental to the environment and pesticides are not always efficient in controlling plant diseases. In addition, it is suspected that conventional agricultural practices have a negative impact on antioxidant activities in red fruits. Therefore new cultural approaches are required in order to produce red fruits of high quality. This involves an integrated programme of plant breeding and development of sustainable agricultural practices. Antioxidant activity was compared in leaves and berries of six raspberry cultivars for the selection of varieties for a breeding programme. This showed that cultivars that had the h…
A multigene phylogenetic study of Tuber aestivum/uncinatum
International audience; Tuber aestivum and Tuber uncinatum share a complicated common history from a taxonomic point of view. Indeed, different previous studies have shown contradictory conclusions. For some authors, Tuber aestivum and Tuber uncinatum are one species and for others, they are two different species. In those studies, few phylogenetic markers have been used, mainly the ITS marker. However, it has become the standard in phylogenetic studies to combine several genes to obtain a more robust phylogenetic representation. In our study, we used 9 molecular markers and sampled fruiting bodies from different European populations including 14 Tuber “aestivum” types and 14 “uncinatum” ty…
