Ecuador has an outstanding diversity of palm species, some of which have been well studied, certain others remain an enigma, however. A particular case is the American oil palm, Elaeis oleifera (Kunth) Cortés, first recorded in Ecuador in 1986. The genus Elaeis has a trans-Atlantic (Africa-America) distribution, with E. oleifera from the Neotropics...

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...
La plupart des espèces végétales sont des polyploïdes récents ou anciens. L'allopolyploïdisation qui résulte d'une hybridation interspécifique couplée à une duplication génomique joue un rôle fondamental dans l'évolution des plantes. Elle provoquerait des changements de l'organisation du génome et de la régulation de l'expression des gènes qui sera...
In the past decade, plant biologists and breeders have developed a growing interest in the field of epigenetics, which is defined as the study of heritable changes in gene expression that cannot be explained by changes in the DNA sequence. Epigenetic marks can be responsive to the environment, and evolve faster than genetic changes. Therefore, epig...

Higher caffeine content and cup beverage bitterness considerably depreciated the commercial value of Coffea canephora Pierre (CAN) compared with C. arabica L (ARA). Wild caffeine-free species like C. pseudozanguebariae Bridson (PSE) offer the opportunity to produce new CAN varieties containing little or no caffeine. F1 plants resulting from a PSE ×...
