Integrating molecular tools with conventional breeding strategies for improving phosphorus acquisition by legume crops in acid soils of Sub-Saharan Africa

Leguminous crops are key components of low input agricultural cropping systems, and play an important role in ensuring food security in many societies in Sub-Saharan Africa (SSA). However, legume crop productivity in SSA is frequently limited by mineral nutrient deficiencies (particularly phosphorus, P). A common remedy for P deficiency is the application of P-fertilizers or in the case of low input cropping systems the...

Developmental competence of in vivo and in vitro matured oocytes: A review

The study of follicular dynamics has been particularly rapid in the last two decades. However,in vitro maturation and fertilization of oocytes results in reduced embryo production, which suggests that not all oocytes have the capacity to mature and to fertilize properly. The efficiency of bovine embryo production in vitro, measured as the blastocyst rate, obtained from oocytes matured and fertilized in...
