“…Such tissue was collected for isolation of the bacterial pathogens. Moreover, molecular identification using 16S rRNA analysis also revealed that the strain in this study was B. gladioli (Gijon‐Hernandez et al., 2011; Nandakumar et al., 2009; Zhang et al., 2020).…”

“…Burkholderia gladioli has been reported to have causes ear soft rot in the United States (Lu et al., 2007) and similar diseases in other plants such as rice (Riera‐Ruiz et al., 2014), gladiolus (Yanez et al., 2022), sweet potato (Zhang et al., 2020), saffron (Fiori et al., 2011) and onion (Serret‐Lopez et al., 2020). Furthermore, leaf stripe and stalk rot of corn caused by B. gladioli was first reported in Mexico (Gijon‐Hernandez et al., 2011).…”

Stalk rot disease is becoming an important disease in sweet corn crops because it causes significant yield losses of the crop. In July 2022, typical symptoms of stem rot were observed in fields of Mae Hia Agricultural Research, Demonstration and Training Center in Chiang Mai province of Thailand. The symptoms exhibited by affected crop included circular water‐soaked lesions, rot and necrotic tissue at the base of the stalk. Koch's postulates were fulfilled with reisolation of the inoculated strain from the inoculated tissues, and confirmation was obtained by phenotypic characters and 16S rRNA sequences. The isolated colony on nutrient agar was cream‐coloured, circular, with a convex elevation, entire margin and smooth surface; the optical character was translucent and exuded a yellowish pigment that diffused in the nutrient agar, gram‐negative, lacked arginine dihydrolase, occurrence of the oxidase and catalase reaction. The strains were able to utilize d‐galactose and glucose but were unable to utilize d‐maltose, d‐cellobiose, d‐fructose, d‐mannose, mannitol, lactose and sucrose. The strains showed positive results for gelatine liquefaction test, citrate utilization and casein hydrolysis, but starch hydrolysis and indole production were negative result. These characteristics are the same as those described previously for Burkholderia gladioli. Disease severity in sweet corn was 43.8%, with infections showing spots with dark margins and soft rot on mature leaves and flag leaves. Disease severity in waxy corn and maize were 21.9% and 15.6%, respectively, showing a few light or dark brown spots at the infection sites. Therefore, this represents the first report of leaf stripe and stalk rot disease in sweet corn in Thailand.

“…However, none of them showed conclusive or reliable evidence to prove or disprove the hypothesis. With the immuno compromised state of pregnancy (Luo and Yin, 2020;Zhang et al, 2020) and various physiological adaptations associated with it, maternal and foetal safety and management have become a major concern for institutions across the globe, especially in developing countries.…”

“…Sweetpotato is an important food source for humans and other animals and serves as pharmaceutical and chemical raw materials. However, the production and quality of sweetpotatoes are significantly limited by Fusarium diseases ( 1 ). The genus Fusarium (Nectriaceae, Hypocreales) comprises at least 450 phylogenetic species within 23 divergent species complexes ( 2 , 3 ).…”

“…However, F. solani-melongenae is morphologically and evolutionarily distinct from F. solani ( 3 , 23 , 28 ). During the past few years, a severe Fusarium disease causing yield loss and quality deterioration of sweetpotatoes, named Fusarium root and stem rot (FRST) by Huang et al ( 1 ), has spread in several main sweetpotato-growing provinces in China, including Guangdong, Zhejiang, Fujian, and Hainan. FRST has gradually become a major sweetpotato disease, but the pathogen remained unidentified.…”

Fusarium root and stem rot in sweetpotato are prevalent in the main sweetpotato-growing areas in China, and fungal isolation, morphological characteristics, and molecular phylogenetic analysis of the disease causal agent ( F. solani-melongenae isolate CRI 24-3) were systematically studied. The genome sequence of F. solani-melongenae isolates CRI 24-3 was first reported, which should provide a basis for genome assembly of other closely related Fusarium species.
