First report of a new postharvest disease of grape caused by Cadophora luteo-olivacea
Springer Science and Business Media LLC - Tập 82 - Trang 116-119 - 2015
Ryoji Nakaune, Miho Tatsuki, Hikaru Matsumoto, Yoshinori Ikoma
A brown skin spot developed on the berries of Japanese grape cultivar Shine Muscat during storage at 0 °C for 3 months. The fungus isolated from these skin spots was identified as Cadophora luteo-olivacea based on the sequence of its ribosomal DNA internal transcribed spacer region. Morphological and culture characteristics corresponded to those reported previously from C. luteo-olivacea; this fun...... hiện toàn bộ
Positive chemotaxis to plant apoplastic fluids of Pseudomonas syringae pv. tabaci 6605 and metabolome analysis
Springer Science and Business Media LLC - Tập 89 - Trang 219-223 - 2023

Pseudomonas syringae pv. tabaci 6605 (Pta6605) is a causal agent of wildfire disease in host tobacco plants. Although chemotaxis has been shown to be necessary for Pta6605 in tobacco infection, the chemoattractants at the site of infection are unclear. Pta6605 was attracted to the apoplastic fluid from not only host tobacco leaves but also non-host plant leaves, indicating that Pta6605 is attracte...... hiện toàn bộ

Distinct phylogenetic positions of Grapevine fanleaf virus isolates from Iran based on the movement protein gene
Springer Science and Business Media LLC - Tập 73 - Trang 209-215 - 2007
Nemat Sokhandan Bashir, Shahrzad Nikkhah, Mohammad Hajizadeh
In DAS-ELISAs of 86 grapevine samples from northwestern Iran, Grapevine fanleaf virus (GFLV) was detected in 18 samples. RT-PCR with two primer pairs (M2/M4 or M0/M4) corresponding to GFLV movement protein (MP) amplified the expected 854- and/or 1,489-bp fragment(s), respectively, from all ELISA-positive samples. Four smaller and three larger PCR products were cloned and sequenced, which revealed ...... hiện toàn bộ
First report of rust disease on ohia and the causal fungus, Puccinia psidii, in Japan
Springer Science and Business Media LLC - Tập 75 - Trang 428-431 - 2009
Takeshi Kawanishi, Seiji Uematsu, Makoto Kakishima, Satoshi Kagiwada, Hiroshi Hamamoto, Hiromichi Horie, Shigetou Namba
In 2007, a rust disease of ohia (Metrosideros polymorpha) was found in Japan. We identified this pathogen as Puccinia psidii based on its morphological characters and the internal transcribed spacer (ITS) sequence of the ribosomal DNA. This pathogen was pathogenic on Eucalyptus amplifolia and E. rudis in addition to previously reported host species. This is the first report in Japan of a rust dise...... hiện toàn bộ
Appearance of a new leaf rot disease on common ice plant
Springer Science and Business Media LLC - Tập 76 - Trang 303-309 - 2010
Kazuyuki Maeda, Yoshio Kurahashi, Shuichi Ohsato, Katsuyoshi Yoneyama
An unknown disease abruptly appeared on hydroponic cultures of common ice plant (Mesembryanthemum crystallinum) in the greenhouse, causing catastrophic damage. Although the symptoms of the plant were unlike typical Botrytis lesions on leaves and stems of other plants, fungi isolated from the necrotic lesions on the plant were similar to genus Botrytis in terms of conidial shape, colony color and n...... hiện toàn bộ
Anthracnose of black locust caused by Colletotrichum nymphaeae (Passerini) Aa
Springer Science and Business Media LLC - Tập 82 - Trang 174-176 - 2016
Naho Yamagishi, Toyozo Sato, Izumi Chuma, Yoshiyuki Ishiyama, Yukio Tosa
Brown spots were found on leaves of black locust (Robinia pseudoacacia L.) in Nagano Prefecture, Japan, in August 2011. A fungus isolated from the diseased leaves reproduced the symptoms after inoculation, and was re-isolated from the lesions. The pathogen was identified as Colletotrichum nymphaeae based on morphological and molecular analyses. This is the first report of C. ...... hiện toàn bộ

Amino Acid Changes in Pepper mild mottle virus Coat Protein That Affect L 3 Gene-mediated Resistance in Pepper
Springer Science and Business Media LLC - Tập 68 - Trang 155-162 - 2002
Hiroyuki HAMADA, Shigeharu TAKEUCHI, Akinori KIBA, Shinya TSUDA, Yasufumi HIKICHI, Tetsuro OKUNO
Several field isolates of Pepper mild mottle virus (PMMoV) were obtained from Capsicum annuum (L 3 / + ) that exhibited systemic mosaic or systemic necrosis. The deduced amino acid sequences of the coat protein (CP) of these isolates differed from those of previously reported PMMoV strains that are able to overcome L 3 gene-m...... hiện toàn bộ
Phân bố của các gen không gây bệnh avrA và popP1 trong 22 chủng phylotype I của Ralstonia solanacearum ở Nhật Bản Dịch bởi AI
Springer Science and Business Media LLC - Tập 75 - Trang 362-368 - 2009
Yingqin Liu, Ayami Kanda, Akinori Kiba, Yasufumi Hikichi, Kouhei Ohnishi
Phân tích trình tự của các loci hrp và các gen hiệu ứng trong các vùng lân cận đã cho thấy sự tương đồng cao giữa hai chủng phylotype I của Ralstonia solanacearum, GMI1000 và chủng Nhật Bản OE1-1. Phân tích thêm về sự phân bố của avrA và popP1, được biết đến như là các yếu tố xác định phản ứng nhạy cảm cực độ (HR) trên cây thuốc lá Nicotiana tabacum, trong 22 chủng phylotype I của Nhật Bản đã tiết...... hiện toàn bộ
