조성은 ( Sung-eun Cho ),최인영 ( In-young Choi ),신현동 ( Hyeon-dong Shin ) 한국균학회 2017 韓國菌學會誌 Vol.45 No.2

한국에서 가지 흰가루병균으로 Erysiphe cichoracearum, Leveillula taurica, Sphaerotheca fusca 모두 3종이 기록되어 있다. E. cichoracearum은 1969년에 기록된 이후 한국에서 발생하는 가지 흰가루병균으로 여긴다. 1998년에는 L. taurica가 가지 뒷면흰가루병균으로 기록 되었으나, 이후에 추가적인 발생기록은 없었다. 2002년에는 S. fusca가 가지 흰가루병균으로 보고되었다. 필자들은 총 22점의 가지 흰가루병균 시료를 채집하여 현미경 관찰 및 염기서열 분석을 실시하였으며, 그 결과 모두 Podosphaera xanthii로 동정하였다. 따라서 한국에서 가지 흰가루병균은 P. xanthii로 표기하는 것이 옳으며, 시설재배에서 드물게 발견되는 L. taurica는 뒷면흰가루병균으로 구별하는 것이 맞다. 반면에, E. cichoracearum (= Golovinomyces cichoracearum)은 가지 흰가루병균으로 표본이 보존되지 않았으며 이후에 채집되지도 않았다. 더구나 가지에서 기록한 E. cichoracearum의 기재는 일반적인 형태적 변이의 폭을 크게 벗어난다. 따라서 E. cichoracearum 흰가루병균의 존재에 대한 과거의 기록은 오류로 생각 된다. 결국 P. xanthii가 한국의 가지에서 발병하는 흰가루병의 주요 병원균으로 판단되며, L. taurica는 드물게 발생되었던 것으로 판단된다. 이 총설에서는 가지 흰가루병균의 역사와 최신 분류체계에 대하여 자세히 기록하였다. Three species of powdery mildew (Erysiphales) on eggplant (Solanum melongena L.) have been listed in Korea, namely Erysiphe cichoracearum (now genus Golovinomyces), Leveillula taurica, and Sphaerotheca fusca (now genus Podosphaera; syn. Podosphaera xanthii). Since E. cichoracearum was recorded on eggplant for the first time in Korea in 1969, it has been regarded as a major powdery mildew agent on that plant. In 1998, the causal agent of powdery mildew on eggplant was recorded as L. taurica, then as S. fusca in 2002. During our extensive field surveys in Korea, we collected 22 samples of eggplant powdery mildews. Our microscopic observations and molecular sequence analyses showed that all of our samples belonged to the genus Podosphaera, in the absence of either E. cichoracearum or L. taurica, suggesting that P. xanthii is the dominant agent of powdery mildew disease on eggplants in Korea. As there have been no additional findings on L. taurica after the first report on the species, it seems to be a minor species that is rarely found in greenhouses. The presence of E. cichoracearum (syn. Golovinomyces cichoracearum s. lat.) on eggplants is questionable, as the morphological characteristics of E. cichoracearum in the original description of the Korean collection deviate from the morphological variations of this species. In addition, no herbarium material of E. cichoracearum remains. Consequently, it seems that P. xanthii is the main species of powdery mildew on eggplants, whereas L. taurica occurs rarely on eggplants, in Korea. This review provides the historical and recent taxonomy of eggplant powdery mildews in detail.

Diane Avalos-Ruiz,Gwang-Jae Lim,Seong-Keun Lim,Ten Leonid N.,Kang In-Kyu,Lee Seung-Yeol,Jung Hee-Young 한국균학회 2022 韓國菌學會誌 Vol.50 No.4

In this study, the fungal strain KNUF-21-F39 was isolated from a declined apple tree (Malus domestica) in the Chungcheongbuk province in Korea. The strain KNUF-21-F39 presented a slow growth rate and a variety of macroconidia shapes and sizes ranging from ovoid to fusoid and 1- to 5-septate, primarily showing 3- and 4-septate, with “S” -shaped macroconidia rarely observed. The strain was identified based on morphological characteristics along with phylogenetic analysis performed using the internal transcribed spacer region (ITS) and partial sequences of translation elongation factor 1-α (tef1), RNA polymerase largest subunit (rpb1), and calmodulin (cal ) genes. The fungal strain KNUF- 21-F39 was identified as Fusarium diversisporum, which has not been previously reported in Korea. The ice nucleation activity (INA) of the strain was also evaluated, identifying the strain as positive for INA. This is the first report characterizing F. diversisporum as an IN-active fungal species.

Vertical Transmission of RNA Mycoviruses in Lentinula edodes

Kim Eunjin,Park Mi-Jeong,Min-Jun Kim,Yeun Sug Jeong,Jang Yeongseon,Ka Kang-Hyeon 한국균학회 2022 韓國菌學會誌 Vol.50 No.4

Lentinula edodes is an important commercial mushroom and there have been several reports of viral infections in L. edodes. Two mycoviruses (LeV-HKB and LeNSRV1) were detected in Sanbaekhyang (NIFoS 2778) and Taehyanggo (NIFoS 4317), the sawdust- cultivated commercial strains. The vertical transmission rates of the viruses were investigated by detecting the viruses in 80 monokaryotic strains derived from basidiospores isolated from the fruiting bodies of each strain. Most of the monokaryotic strains were infected with the virus and the two viruses showed different levels of meiotic stability, with LeV-HKB showing higher meiotic stability than LeNSRV1. Therefore, it seems that the vertical transmission mechanism of mycoviruses is different depending on the virus species. We also examined the mycelial growth rate of the monokaryotic strains and compared the growth rate according to virus infection status. Although there was no statistically significant correlation between viral infection and mycelial growth rate, we found that the average growth rate was reduced by additional virus infection. We expect our data to contribute to a greater understanding of the mechanism of the vertical transmission of mycoviruses, and promoting breeding using virus-free monokaryotic strains.

Acrodontium burrowsianum and Pestalotiopsis humicola : Two Previously Unrecorded Fungal Species Isolated from Conifer Leaves in Korea

Jae-Wook Choi,Jung-Min Lee,Seok-Yong Park,Eom Ahn-Heum 한국균학회 2022 韓國菌學會誌 Vol.50 No.4

Endophytic fungal strains were isolated from the leaves of two conifer species (Juniperus rigida and Pinus densiflora) in Korea and identified on the basis of their morphological and molecular characteristics. Internal transcribed spacer and large subunit regions of rDNA were used for the phylogenetic analysis, and the translation elongation factor 1-alpha (TEF) and RNA polymerase II second largest subunit (RPB2) genes were analyzed depending on the species. Two fungal species that were previously unrecorded in Korea were identified: Acrodontium burrowsianum and Pestalotiopsis humicola. Their morphological and phylogenetic characteristics are described herein.

Mycorrhization of Quercus acutissima with Tuber borchii and Tuber melanosporum

Jung-Min Lee,Ahn-Heum Eom 한국균학회 2022 韓國菌學會誌 Vol.50 No.4

Truffles are ectomycorrhizal fungi that belong to the genus Tuber. They exhibit symbiotic relationships, particularly with oak (Quercus spp.) and hazel (Corylus spp.) trees. We performed an inoculation using a spore suspension to synthesize mycorrhizae between European truffles, Tuber borchii and Tuber melanosporum, and an indigenous oak species, Quercus acutissima. This resulted in the formation of mycorrhizae within 2 months after inoculation. Despite having the same host plant, differences in features were observed between Tuber species, including color and mantle type. These results indicate that Q. acutissima is a suitable host plant for truffle cultivation in Korea and provide a better understanding of the mycorrhization of T. borchii and T. melanosporum.

백지선,나주영,이미정,임수빈,최정혜,장자영,이데레사,최효원,김점순 한국균학회 2022 韓國菌學會誌 Vol.50 No.4

Fusarium head blight is an important disease of small grains. It is mainly caused by members of the Fusarium graminearum species complex (FGSC). Barley and wheat growers spray fungicides, especially demethylation-inhibitor fungicides, to suppress the disease. The objective of this study was to examine the changes in the sensitivity of the FGSC population to the triazole fungicide, propiconazole. A total of 124 and 350 isolates of FGSC were obtained from barley and wheat in Jeolla Province during 2010-2016 and 2020-2021, respectively. The species identity and trichothecene chemotypes of the FGSC isolates were determined based on polymerase chain reaction assays targeting translation elongation factor 1-alpha and TRI12 genes, respectively. Sensitivity to propiconazole was determined based on the effective concentration that reduced 50% of the mycelial growth (EC50) using the agar dilution method. Of all isolates, F. asiaticum with the nivalenol chemotype was the most common (83.9% in 2010-2016 and 96.0% in 2020-2021), followed by F. asiaticum with the 3-acetyl deoxynivalenol chemotype (12.1% in 2010-2016 and 2.9% in 2020-2021). The EC50 values of the isolates collected in 2010-2016 and 2020-2021 ranged from 0.0180 to 11.0166 μg/mL and 1.3104 to 17.9587 μg/mL, respectively. The mean EC50 value of the isolates increased from 3.8648 μg/mL in 2010-2016 to 5.9635 μg/mL in 2020-2021. The baseline resistance to propiconazole was determined to be 7 μg/mL, based on the EC50 value of isolates collected in 2010-2016, and the ratio of resistant isolates increased from 9.7% in 2010-2016 to 28.6% in 2020-2021.

Occurrence in Korea of Rust Disease on Tilia mandshurica Caused by Pucciniastrum tiliae

Lee Jae Sung,박지현,Choi Young-Joon,Shin Hyeon-Dong 한국균학회 2023 韓國菌學會誌 Vol.51 No.1

Tilia mandshurica trees with rust symptoms have consistently been noticed during disease surveys in Korea since 2006. Based on the morphological examination and molecular sequence analysis of the internal transcribed spacer and large subunit of ribosomal DNA, Pucciniastrum tiliae was identified as the causal fungus of rust disease. This is the first report of P. tiliae infection on T. mandshurica in Korea.
