“…Various of Fusarium (Fusarium oxysporium, Fusarium solani, Fusarium equiseti, Fusarium avenacearum, Fusarium colmorum and Fusarium sambicum) were identified as being responsible for potato fusariosis in the Far North Region. These results are in agreement with those identified in North America, China and parts of Europe by [22,23]. These authors reported the presence of Fusarium sambicum as the most prevalent fungus in these regions.…”

“…It is estimated that there are thirteen species of Fusarium causing potato fusariosis depending on agro-ecological zones [16] edaphic factors, environmental factors [17,18], climatic factors [18,19] and cultivars. Nevertheless, Fusarium sambicum is the most widespread fungus in North America, China and parts of Europe [20][21][22][23]. Fusarium coeruleum is the most widespread agent in the United Kingdom [22].…”

Introduction: Potato production in the Far North Region, Cameroon is hampered by a wide range of fungi of the genus Fusarium. Aims: The aim of this work was to isolate and conduct physiological characterization of Fusarium spp. isolates responsible for potato Fusarium disease in the Far North Region, Cameroon. Methodology: Isolates were obtained from diseased organs (leaves) from fifteen villages in the district of Mogodé, Mokolo and Koza, Far North Cameroon. The species responsible for fusariosis were identified using several identification Keys on a base of symptoms and morphological spores characteristics (macroconidia, microconidia and chlamydospores). Fusarium incidence and rainfall were assessed. Radial growth, sporulation and pathogenicity of the isolates were use to evaluated the parameters of physiological characterization. Results: The overall average incidence of Fusarium head blight in the Far North Region, Cameroon is 29.36%. Furthermore, out of the 20 isolates obtained, six Fusarium species (Fusarium oxysporium, F. solani, F. equiseti, F. avenacearum, F. colmorum and F. sambicum) were identified. The highest growth rate (8.1 cm), the highest spore production (8 × 105) and the highest severity index (3%) were respectively obtained with the isolates FUROM 2 and FUTEK 3, FUMOG 1, FUMOG 2, FUROM 1 and FURAF from Mogodé District on PCA medium. Conclusion: Potato production in the Far North Region, Cameroon is confronted by various Fusarium species which have physiological characteristics that vary according to the area of origin of the isolates and the growing media.

“…The comparative genomics studies between dry rot causing Fusarium spp. revealed that F. sambucinum possesses perfect microsatellites while F. verticelloides microsatellites are in the compounded form (Patil et al 2017). There are very limited genes characterized in F. sambucinum, such as major facilitator superfamily (MSF) genes which were confirmed within the genome sequence.…”

“…An one-way average nucleotide identity (ANI) among Fusarium spp. by comparing 100 housekeeping gene sequences revealed the closest association between F. sambucinum (Strain FS-4) and F. graminearum (Strain PH-1) (99.12%) (Patil et al 2017). However, the least relationship was observed with F. verticillioides (Strain 7600) (97.81%).…”

“…The current scenario demands an exhaustive screening of available cultivars and potato germplasms to identify the source of resistance and to frame a suitable breeding program. Also with the availability of the genome sequence of F. sambucinum (Patil et al 2017), it is important to identify the potential pathogenicity factors and small secreted proteins that can be targeted in developing dsRNA based therapeutic biomolecules for seed tuber treatment. The role of multifunctional phytoprotectant, such as melatonin and strigolactones is also need to be explored which is highly effective in managing post-harvest losses in horticultural crops (Tiwari et al 2020b).…”

Potato dry rot disease caused by Fusarium species is a major threat to global potato production. The soil and seed-borne diseases influence the crop stand by inhibiting the development of potato sprouts and cause severe rots in seed tubers, table and processing purpose potatoes in cold stores. The symptoms of the dry rot include sunken and wrinkled brown to black tissue patches on tubers having less dry matter and shriveled flesh. Fungal infection accompanied by toxin development in the rotten tubers raises more concern for consumer health. The widespread dry rot causing fungal species (Fusarium graminearum) is reported to have a hemibiotrophic lifestyle. A cascade of enzymes, toxins and small secreted proteins are involved in the pathogenesis of these hemibiotrophs. With the availability of the genome sequence of the most devastating species Fusarium sambucinum, it is important to identify the potential pathogenicity factors and small secreted proteins that will help in designing management strategies. Limited resistant cultivars and the emergence of fungicide-resistant strains have made it more threatening for potato cultivation and trade. Several novel fungicide molecules (Azoxystrobin, chlorothalonil and fludioxonil), are found very effective as tuber treatment chemicals. Besides, many beneficial bioagents and safer chemicals have shown antibiosis and mycoparasitism against this pathogen. Germplasm screening for dry rot resistance is important to assist the resistance breeding program for the development of resistant cultivars. This review aims to draw attention to the symptomatology, infection process, pathogenomics, the role of toxins and management approaches for potato dry rot disease, which is very much critical in designing better management strategies.
