Clonal population structure and genetic diversity of Candida albicans in AIDS patients from Abidjan (Cote d'Ivoire)

Honeybee populations in Côte d’Ivoire have been previously identified as belonging to one subspecies, Apis mellifera scutellata, but other studies have since reported a mixed population consisting of A. m. adansonii and A. m. jemenitica. The population structure and the geographic distribution of honeybees in Côte d’Ivoire remain unclear. This study aimed to profile the population structure of honeybees and their biogeography in Côte d’Ivoire. A total of 33 honeybee colonies were sampled from 15 localities to investigate the maternal ancestry of indigenous honeybee populations using the DraI COI-COII mtDNA test. The results revealed that the honeybee population in Côte d’Ivoire is composed of African haplotypes, all belonging to the AI sublineage. Haplotypes A1 and A4 were recorded with five new sequence variants, including three types of haplotype A1 and two types of haplotype A4. The A1e variant was the most frequent in the A. m. adansonii distributional area. The distribution of the haplotype variants was correlated with the climate pattern in Côte d’Ivoire. This is the first study in Côte d’Ivoire that gives insights into the biogeography and mitotype structure of the local honeybee populations.

Seed System

The survey aims at assessing current managing status of organizations involves in the conservation of local genetic diversity of rice, maize, sorghum and pearl millet in seedbanks located in northern Côte d’Ivoire. An investigation was conducted with 100 respondents in charge of cereal seedbanks managing from Ferkessedougou and Ouangolodougou areas. The results at regional scale revealed two co-existing informal and formal systems for seedbanks management in these areas. The farmers’ seedbanks system or informal system was the main source of cereal seed supply for farmers and more important than the national or formal seedbank system. Only, farmers’ seedbanks of two crops, rice and maize were found in visited localities. The management of these farmers’ seedbanks was enabled by associations or cooperatives gathering more men (78.27%) than women (21.73%). Ninety percent (90%) of respondents were identified as saving 1 to 3 traditional varieties of cereal in these seedbanks managed by farmers in the studied region. The reveled difficulties in the farmers’ seedbanks management appeared mainly as informally organized seed system that must be a complementary approach to formal system or national seed system for genetic diversity preservation of local cereal varieties and also as a distribution channel of improved cereal varieties.

Water Yam

Dioscorea alata (L.), also referred to as water, winged, or greater yam, is one of the most economically important staple food crops in tropical and subtropical areas. In Côte d’Ivoire, it represents, along with other yam species, the largest food crop and significantly contributes to food security. However, studies focusing on better understanding the structure and extent of genetic diversity among D. alata accessions, using molecular and phenotypic traits, are limited. This study was, therefore, conducted to assess the pattern of genetic variability in a set of 188 D. alata accessions from the National Agronomic Research Centre (CNRA) genebank using 11,722 SNP markers (generated by the Diversity Arrays Technology) and nine agronomic traits. Phylogenetic analyses using hierarchical clustering, admixture, kinship, and Discriminant analysis of principal component (DAPC) all assigned the accessions into four main clusters. Genetic diversity assessment using molecular-based SNP markers showed a high proportion of polymorphic SNPs (87.81%). The analysis of molecular variance (AMOVA) showed low molecular variability within genetic groups. In addition, the agronomic traits evaluated for two years in field conditions showed a high heritability and high variability among D. alata accessions. This study provides insights into the genetic diversity among accessions in the CNRA genebank and opens an avenue for sustainable resource management and the identification of promising parental clones for water yam breeding programs in Côte d’Ivoire.
