Two serologically unrelated sweet potato viruses causing symptoms of vein clearing in the indicator plant Ipomoea setosa were isolated and their genomes have been sequenced. They are associated with symptomless infections in sweet potato but distinct vein-clearing symptoms and higher virus titres were observed when these viruses co-infected with sweet potato chlorotic stunt virus (SPCSV), a vir...

O objetivo foi avaliar o crescimento das plantas, produção de raízes batata-doce (Ipomoea batatas) e grãos milho pipoca (Zea mays) em sistema cultivo solteiro consorciado. Foram avaliadas quatro cultivares uma blocos casualizados com três repetições condições campo. No solteiro, a foram espaçadas 75 cm entre linhas. consorciado, plantio da no centro linhas pipoca. A adubação realizada cama fran...

Abstract China is the world’s largest producer of sweet potato ( Ipomoea batatas (L.) Lam.). Considering that there are numerous potato-producing regions in and a vegetatively propagated crop, genetic diversity viruses could be high country. However, studies on species variabilities limited, making it difficult to prevent control viral diseases this crop. During 2014–2019, samples with disease-...

After a wound-desiccation stress, plant tissues can secrete products that have specific cytotoxicity against melanoma B16 cells. Healthy plant or animal cells were not susceptible to these products. Secretion of the active product varied with the plant species and the plant organs. The secretion of tubers of yam (Dioscorea cayenensis Lam), cassava (Manihot esculenta), Jerusalem artichoke (Helia...

The accumulation of industrial by-products increases the use sweet potato waste for ruminants, but ruminal pH characteristics are still not well known. objective was to assess fluctuation in sheep supplemented with different levels flour inclusion their diet. Four rumen-fistulated were used; they fed a diet based on ryegrass haylage (Lolium multiflorum) and (Ipomoea batatas), provided according...

Sweet potato production is constrained by Fusarium wilt, which is caused by Fusarium oxysporum f. sp. batatas (Fob). The identification of genes related to disease resistance and the underlying mechanisms will contribute to improving disease resistance via sweet potato breeding programs. In the present study, we performed de novo transcriptome assembly and digital gene expression (DGE) profilin...

Sub-Saharan agriculture has been identified as vulnerable to ongoing climate change. Adaptation of agriculture has been suggested as a way to maintain productivity. Better knowledge of intra-specific diversity of varieties is prerequisites for the successful management of such adaptation. Among crops, root and tubers play important roles in food security and economic growth for the most vulnera...

Currently the world is moving towards organic production of crops for the discovered and envisaged advantages. Despite this, farmers are faced with the challenges of the bulkiness of organic fertilizer to be used and further gains that could be accrued from it even if sacrifice of using it is made. To be quite sure of the appropriate fertilizer type to be used in improving quality as well as th...

Sweet potato proteins have been shown to possess antioxidant and antidiabetic properties in vivo. The ability of a protein to exhibit systemic effects is somewhat unusual as proteins are typically susceptible to digestive enzymes. This study was undertaken to better understand how digestive enzymes affect sweet potato proteins. Two fractions of industrially processed sweet potato peel, containi...
