Fungal genus causes diseases in a wide range of plants. Here, we report the first genome sequences of two strains of , the causal agent of the pasmo disease of flax (). The genome of the first strain, SE15195, was fully assembled in 16 chromosomes, while 35 unitigs were obtained for a second strain, SE14017.

Paleo-environmental data show that the distribution of African rain forests was affected by Quaternary climate changes. In particular, the Dahomey Gap (DG) - a 200 km wide savanna corridor currently separating the West African and Central African rain forest blocks and containing relict rain forest fragments - was forested during the mid-Holocene and possibly during previous interglacial periods, whereas it was dominated by open vegetation (savanna) during glacial periods. Genetic signatures of past population fragmentation and demographic changes have been found in some African forest plant species using nuclear markers, but such events appear not to have been synchronous or shared across species.

Detarioideae is well known for its high diversity of floral traits, including flower symmetry, number of organs, and petal size and morphology. This diversity has been characterized and studied at higher taxonomic levels, but limited analyses have been performed among closely related genera with contrasting floral traits due to the lack of fully resolved phylogenetic relationships. Here, we used four representative transcriptomes to develop an exome capture (target enrichment) bait for the entire subfamily and applied it to the Anthonotha clade using a complete data set (61 specimens) representing all extant floral diversity.

Paleo-environmental reconstructions show that the distribution of tropical African rain forests was affected by Quaternary climate changes. They suggest that the Dahomey Gap (DG)-the savanna corridor that currently separates Upper Guinean (UG, West Africa) and Lower Guinean (LG, western Central Africa) rain forest blocks-was forested during the African Humid Holocene period (from at least 9 ka till 4.5 ka), and possibly during other interglacial periods, while an open vegetation developed in the DG under drier conditions, notably during glacial maxima.

Premise Of The Study: (Fabaceae) is a common tree species throughout the Guineo-Congolian forest that is sometimes confounded with other congeneric species; it is expected to be an interesting phylogeographical model to infer the history of the African dense forests. We developed 18 microsatellite markers from this species and tested their transferability in 15 congeneric species.

Methods And Results: A genomic library was obtained using the Illumina platform, and 18 polymorphic microsatellite loci were developed.

Premise Of The Study: Microsatellites were designed and characterized in the African timber forest tree Terminalia superba (Combretaceae). Due to their high variability, these markers are suitable to investigate gene flow patterns and the structure of genetic diversity.

Methods And Results: From a genomic library obtained by next-generation sequencing, seven monomorphic and 14 polymorphic microsatellite loci were developed.
