“…Other regions including beta-tubulin (TUB), translation elongation factor (TEF), histone H3 (H3), and calmodulin (CAL) have been analyzed in previous studies of Diaporthe (Dissanayake et al 2020;Udayanga et al 2014). Regarding to studies of D. destruens, Maeda et al (2022) analyzed ITS, TUB, TEF, H3, and CAL regions to show that D. destruens isolates from Okinawa, Japan are grouped into the same clade with isolates from China, Taiwan, and South Korea. Following to this study, analyzing these genomic regions of strains collected in the other places of Japan would be valuable to discover genetic relationships between domestic and foreign strains.…”

To discover genetic relationships between domestic and foreign strains of Diaporthe destruens, 135 strains of D. destruens were collected in Japan, and ITS, TUB, TEF, H3, and CAL regions were sequenced. All collected strains had the same sequences in each region, implying high genetic homogeneity of collected strains. A phylogenetic tree was constructed for ITS sequence with foreign strains. In the tree, our samples were positioned closely to Korean and Chinese samples but distant from most of the Taiwanese samples. Our study provides an insight into genetic diversity of D. destruens, which has been spreading in Japan.

“…Based on information in NCBI, a sequence LC460475 is obtained from a strain OK-9. Another name of OK-9 is MAFF246953 (Maeda et al 2022), which is sequenced to produce LC624790. Considering that LC624790 belongs to group 1, there are two possibilities: a strain OK-9/MAFF246953 belongs to group 1 or group 2.…”

“…China is the world's largest sweet potato producer. According to statistics, in 2020, sweet potato production in China was 5126.4×104 t, accounting for 56% of the world's total production (Maeda et al, 2022). Due to its sweet taste and richness in starch, carotene, edible fiber, a variety of amino acids, and minerals including calcium, phosphorus, iron, and potassium, sweet potatoes exert anti-cancer, anti-aging, and anti-atherosclerotic effects as well as other health-promoting effects such as enhancing immune function.…”

To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential oils (citral, Litseacubeba, parsley, eugenol, and chinaberry tree oils) that significantly inhibited the spoilage bacterial species were identified after screening 20 plant essential oils using the zone of inhibition test. Minimum Inhibitory Concentrations (MICs) of Litsea cubeba, eugenol, and parsley oils against the above three spoilage bacteria were 320-1280, 640-1280, and 320-640 μL/L, respectively. The three essential oils exhibiting the most favorable inhibitory effects were selected for combinatorial studies. Finally, the response surface methodology was used to optimize the combination concentration of Litsea cubeba, eugenol, and parsley oils. The optimum concentration was identified as follows: 320 μL/L for Litsea cubeba oil, 716 μL/L for parsley oil, and 1280 μL/L for eugenol oil. At this concentration, the growth of three spoilage bacteria was almost completely inhibited (OD values of 0.067, 0.202, and 0.013). The optimized compound essential oil exhibited potent inhibitory activity against the spoilage bacteria of sweet potatoes. The aforementioned studies may provide important guidance for the development of efficient and broad-spectrum sweet potato preservatives.
