Abstract The Vanilla genus is a complex taxonomic group characterized by vegetative reproduction mode combined with intra- and inter-specific hybridizations, polyploidy events. These factors strongly impact the diversification of complicate delimitation taxa. Among hundred species, planifolia Jacks. ex Andrews × tahitensis J. W. Moore are main cultivated aromatic species. We applied Genotyping-by-Sequencing to explore genetic diversity these two vanilla seven closely related species nineteen...
The timing of floral budbreak in apple has a significant effect on fruit production and quality. Budbreak occurs as result complex molecular mechanism that relies accurate integration external environmental cues, principally temperature. In the pursuit understanding this mechanism, especially with respect to aiding adaptation climate change, QTL at top linkage group (LG) 9 been identified by many studies budbreak, but genes underlying it remain elusive. Here, together dessert core collection...
Among semi-aquatic species of the legume genus Aeschynomene, some have property being nodulated by photosynthetic Bradyrhizobium lacking nodABC genes necessary for synthesis Nod factors. Knowledge specificities underlying this Nod-independent symbiosis has been gained from model Aeschynomene evenia but our understanding remains limited due to lack comparative genetics with related taxa using a factor-dependent process. To fill gap, we combined different approaches perform thorough analysis...
Backgrounds and aims – Previous studies showed that robusta coffee (Coffea canephora Pierre ex A.Froehner), one of the two cultivated species worldwide, can be classified in genetic groups: Guinean group originating Upper Guinea Congolese Lower Congolia. Although C. is an important resource for improvement coffee, its germplasm under-represented situ gene banks diversity population structure have not yet been investigated.
