Taro (Colocasia esculenta (L.) Schott) is widely distributed in tropical and sub-tropical areas. However, its origin, diversification dispersal remain unclear. While taro genetic diversity has been documented at the country regional levels Asia Pacific, few reports are available from Americas Africa where it introduced through human migrations. We used eleven microsatellite markers to investigate of accessions nineteen countries Asia, America. The highest number private alleles were observed...
Abstract Evidence for seed transmission of phytoplasmas has grown in several pathosystems including coconut ( Cocos nucifera ). Bogia syndrome (BCS) is a disease associated with the lethal yellowing presence ‘ Candidatus Phytoplasma noviguineense’ that affects coconut, betel nut Areca catechu ) and bananas Musa spp.) Papua New Guinea. Coconut drupes were sampled from BCS-infected areas Guinea, dissected, extracted nucleic acid was used polymerase chain reaction (PCR), loop mediated...
Sorghum ergot was first discovered in Australia 1996. It affects seed production and grain usage stock feed due to concerns of animal toxicity. Three species Claviceps are known cause sorghum with different epidemiological, toxicity, management implications. africana identified as the causal agent but morphological differences between isolates raised possibility more than one being involved. The major aim this study identify causing determine genetic diversity among pathogen from overseas....
Abstract Understanding root development in soil profiles of agroforestry systems is challenging. It uncertain to what extent the proximity cash crops, such as cocoa and coffee, shade trees reduces nutrient concentrations topsoil whether crops continue develop fine roots when they are planted close trees. We aimed investigate micro‐ macro‐nutrient profile understand architecture using a novel DNA metabarcoding approach an system where coffee were interplanted with tree, canarium. Soil samples...
(1) Background: The oil stability of tree nuts during storage can be influenced by conditions such as temperature, humidity, and moisture concentration. However, few studies have assessed how the presence testa shell affects storage. We aimed to determine affect in almond canarium, particular, time nut-in-shell (NIS). (2) Methods: measured peroxide value (PV), free fatty acid (FFA) hexanal concentrations canarium (blanched vs. kernel-in-testa) stored at 45 °C for 24 days. also PV, FFA...
Ergot, caused by Claviceps africana , has emerged as a serious threat to sorghum hybrid seed production worldwide. In the absence of gene‐for‐gene‐based qualitative resistance in commercial cultivars, varieties with high pollen that can escape ergot infection are preferred. Recent demonstration differences susceptibility among male‐sterile lines indicated presence partial resistance. Using chitin‐specific fluorescin‐isothiocyanate‐conjugated wheat germ agglutin and callose‐specific aniline...
Summary Cereal grains such as maize and wheat are used extensively in feed formulations for poultry the primary source of carbohydrates. High cost these many developing countries necessitates evaluation other ingredients that grown locally. Sweet potato is one crop. The study was conducted a proof concept experiment to test hypothesis presence absence enzyme, sweet roots when included diets broiler chickens may affect total metabolisable energy content which exert certain influences on dry...
Abstract The Pacific Islands (Melanesia, Micronesia, Polynesia) were the last region in world to be colonized by modern humans. In their migrations, they dispersed asexually propagated food plants that first domesticated Melanesia and exposed them further selection diverse insular environments. Later, staple crops introduced from South America. our search for research on genetic resources characterization breeding conducted between 1950 2022, we retrieved 338 references 13 crop species. All...
