“…Furthermore, percentage of polymorphic loci estimated at 99% confirms a high level of polymorphism of SNPs as stated by Ji et al (2012) and Forrest et al (2014). This percentage of polymorphic loci is higher than that obtained with RAPD markers in C. nitida (71.47%), and on five other Cola species (28.5%) in Nigeria (Akinro et al 2019;Wood and Ohimain 2020). These results illustrate the effectiveness of SNPs for genetic diversity analysis in kola tree compared to other molecular markers including RAPDs.…”

Abstract. Ouattara Y, Koffi KG, Séry DJ-M, Saraka DM, Pokou ND, Gba KKM, Bonsson B, Akaffou DS, Sié RS. 2022. Genetic diversity and structure of kola tree (Cola nitida) clones germplasm in Côte d’Ivoire using Single Nucleotide Polymorphism markers. Biodiversitas 23: 4677-4685. The kola nut comes from the cola tree (Cola nitida [Vent.] Schott & Endl.), a product of economic interest to Côte d’Ivoire. The country is the leading producer and exporter. However, much of its collection has been destroyed due to urbanization and deforestation. This has resulted in the loss of much of its genetic diversity. This study aimed to determine genetic diversity and structure of C. nitida in Côte d’Ivoire using Single Nucleotide Polymorphism (SNPs) markers. Thirty clones from Côte d’Ivoire (14 clones) and Nigeria (16 clones) cultivated in CNRA (Centre National de Recherche Agronomique) were analyzed using 145 SNPs. GBS (Genotyping by Sequencing) technique was used for the genotyping. The results confirmed the existence of both origins (Côte d’Ivoire and Nigeria) by analyzing clones’ genetic structure and the principal coordinate analysis. The genetic diversity obtained was higher within origins than among origins. The two origins showed moderate differentiation (FST = 0.11) and the genetic distance was 0.46. The 30 clones were subdivided into six subgroups partially overlapping the geographical origins. Genetic differentiation among subgroups was moderate to very strong (FST ranging from 0.10 to 0.26). Four clones from Nigeria were close to those from Côte d’Ivoire. This genetic structuring highlights the possibilities for genetic improvement of kola trees in Côte d’Ivoire.

“…In addition, G. kola and Cola spp. have been characterized in Nigeria and Benin using Random Amplified Polymorphic DNA [300,306] and microsatellites markers, respectively [244]. The knowledge of genetic diversity within and among studied populations in these countries provide important information for the assessment of the domestication strategies and their influence on the conservation of the genetic resources of the targeted species [244,245,312].…”

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?

“…Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of seed storage protein is a reliable technique to examine the genetic differences and relationships among plant varieties (Payne & Lawrence, 1983;El-Sheekh & Abomohra, 2020;Elghamery et al, 2021) and to study the intra-and inter-species variations in plants (Sofalian et al, 2015). Molecular systematics is still considered the most accurate tool for clarifying the diversity among species (Wood & Ohimain, 2020).…”

I N THIS study, we evaluated the storage proteins, macro-and micromorphological characters of seeds from 49 species belonging to 34 genera and seven subfamilies of the Malvaceae s.l. (i.e, Malvaceae s.s., Bombacaceae, Sterculiaceae, and Tiliaceae) along with one representative of the Elaeocarpaceae as an outgroup. We obtained microphotographs of the specimens using both light and scanning electron microscopes. The seed storage protein was subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). We analyzed 73 recorded characters (with 157 characters-states) were analyzed using the upgraded WinClada and TNT cladistic programs. A cladogram was constructed which indicated a clear indication about the systematic position between the studied species within the Malvaceae s.l. The results showed specific synapomorphic diagnostic characters are quite significant in species delimitation within the Malvaceae s.l. viz., including seed shape, apex, base, colour, size, texture, hilum shape, position, seed coat sculpture patterns, and occurrence of strophioly. Our results also support the monophyly of the studied genera in Malvioideae except for Gossypium and Thespesia, while para-polyphyly in the other six subfamilies.
