Genomic footprints of selection in early-and late-flowering pearl millet landraces.

Pearl millet is among the top three-cereal production in one of the most climate vulnerable regions, sub-Saharan Africa. Its Sahelian origin makes it adapted to grow in poor sandy soils under low soil water regimes. Pearl millet is thus considered today as one of the most interesting crops to face the global warming.

Role of seed flow on the pattern and dynamics of pearl millet (Pennisetum glaucum [L.] R. Br.) genetic diversity assessed by AFLP markers: a study in south-western Niger.

We studied the regional genetic diversity and seed exchange dynamics of pearl millet landraces in south-western Niger. The genetic study was based on AFLP markers. We found significant genetic differentiation between landraces in different geographical areas of south-western Niger.

Genetic diversity and gene flow among pearl millet crop/weed complex: a case study.

Weedy plants with intermediate (domesticated x wild) phenotypes occur in most pearl millet fields in West Africa, even in the absence of wild populations. They are usually found, in high numbers, both inside and outside of drills. Questions pertaining to the evolutionary dynamics of diversity within the pearl millet complex (domesticated-weedy-wild forms) were addressed in this study.

[Senegalese pharmacopoeia: study of acute toxicity and antitussive activity of Calotropis procera AIT (Asclepiadaceae)].

We confirmed the innocuity of different extracts (leaves and stem bark) of Calotropis procera (Asclepiadaceae), a plant widely used in Asian and West African traditional therapy in dermatological and bronchal affections. We proved the against cough activity of the aqueous stem bark extract after administration, per os, upon bronchal irritation by ammoniac on Guinea Pig.
