Temporal dynamics of seed excretion by wild ungulates: implications for plant dispersal.
Published in Ecology and evolution
Dispersal is a key process in metapopulation dynamics as it conditions species' spatial responses to gradients of abiotic and biotic conditions and triggers individual and gene flows. In the numerous plants that are dispersed through seed consumption by herbivores (endozoochory), the distance and effectiveness of dispersal is determined by the comb...
Farmer seed networks make a limited contribution to agriculture ? Four common misconceptions
...
The importance of seed provisioning in food security and nutrition, agricultural development and rural livelihoods, and agrobiodiversity and germplasm conservation is well accepted by policy makers, practitioners and researchers. The role of farmer seed networks is less well understood and yet is central to debates on current issues ranging from se...
Local evolution of seed flotation in Arabidopsis.
...
Published in PLoS genetics
Arabidopsis seeds rapidly release hydrophilic polysaccharides from the seed coat on imbibition. These form a heavy mucilage layer around the seed that makes it sink in water. Fourteen natural Arabidopsis variants from central Asia and Scandinavia were identified with seeds that have modified mucilage release and float. Four of these have a novel mu...
Phenotypic and molecular characterization of plants regenerated from non-cryopreserved and cryopreserved wild Solanum ly...
BACKGROUND: Before cryopreservation is routinely used, its effect on the trueness-to-type of the regenerated plant material needs to be evaluated. OBJECTIVE: In this work, we studied the effect of seed cryopreservation on the phenotypic and molecular characteristics of wild Solanum lycopersicum Mill. plants. METHODS: Thirty-five morphological trait...
Frontière des hommes, frontière des plantes cultivées : diffusions et recompositions de l'agro-biodiversité
Un grand nombre de sorghos sont ou ont été la propriété de groupes particuliers, jumeaux ou de cercles d'individus ayant commis des faits de bravoure. Plus souvent il s'agissait de sorghos liturgiques attachés à certains cultes ou à leurs desservants ou encore des sorghos de chefferie. Dans les monts Mandara, ces sorghos sont révélateurs d'un contr...
