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 geneSpringer 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

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
Anthracnose of black locust caused by Colletotrichum nymphaeae (Passerini) AaSpringer Science and Business Media LLC - Tập 82 - Trang 174-176 - 2016

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.

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

A simple loop-mediated isothermal amplification assay to detect Phytophthoracolocasiae in infected taro plantsSpringer Science and Business Media LLC - - 2019
Wenzhuo Feng, Kayoko Otsubo, Ayaka Hieno, Haruhisa Suga, Koji Kageyama
In Japan, Phytophthoracolocasiae causes leaf blight of taro, resulting in huge losses. To effectively diagnose this pathogen in the field, we developed rapid and reliable methods based on loop-mediated isothermal amplification (LAMP) using LAMP primers designed from the Ypt1 gene that are highly specific with a sensitivity of 100 fg. Among these methods, we concluded that the plant-LAMP method wit...... hiện toàn bộ
Molecular characterization and variability analysis of Apple scar skin viroid in IndiaSpringer Science and Business Media LLC - Tập 75 - Trang 307-311 - 2009

Apple scar skin viroid (ASSVd) infection is a major limitation to apple fruit quality and causes huge economic losses. In surveys of apple orchards in the northern Indian state of Himachal Pradesh, fruits with dappling symptoms were noticed. ASSVd was detected from these fruits and molecularly characterized. Ten clones from three isolates were sequenced, of which seven wer...... hiện toàn bộ
