“…The sexual state is Pestalosphaeria and only 13 species are known as compared to the asexual state (253 species names). Species of Pestalotiopsis cause a variety of disease in plants, including canker lesions, shoot dieback, leaf spots, needle blight, tip blight, grey blight, scabby canker, severe chlorosis, fruit rots and leaf spots (Espinoza et al 2008;Maharachchikumbura et al 2013a, b;Tagne and Mathur 2001). Species belonging to the genus Pestalotiopsis are thought to be a rich source for bioprospecting, and chemical exploration of endophytic Pestalotiopsis species is on the increase (Aly et al 2010;Xu et al 2010Xu et al , 2014.…”

Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineagespecific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae,

“…Besides black spot blight of P. sylvestris var. mongolica, P. neglecta can also cause chlorotic spot in maize (Zea mays), shoot blight in Cryptomeria japonica, and canker disease in blueberries (Vaccinium corymbosum) [8,16,17].…”

Black spot needle blight is a serious conifer disease of Pinus sylvestris var. mongolica occurring in Northeast China, which is usually caused by the plant pathogenic fungus Pestalotiopsis neglecta. From the diseased pine needles collected in Honghuaerji, the P. neglecta strain YJ-3 was isolated and identified as the phytopathogen, and its culture characteristics were studied. Then, we generated a highly contiguous 48.36-Mbp genome assembly (N50 = 6.62 Mbp) of the P. neglecta strain YJ-3 by combining the PacBio RS II Single Molecule Real Time (SMRT) and Illumina HiSeq X Ten sequencing platforms. The results showed that a total of 13,667 protein-coding genes were predicted and annotated using multiple bioinformatics databases. The genome assembly and annotation resource reported here will be useful for the study of fungal infection mechanisms and pathogen–host interaction.

“…It is capable of infecting several plants of economic importance including guava, mango etc. Its infection is manifested by the development various kinds of symptoms (Hopkins and McQuilken, 2000;Keith et al, 2006;Pirone, 1978;Kwee and Chong, 1990;Xu et al, 1999;Tagne and Mathur, 2001;Sousa et al, 2004;Espinoza et al, 2008). In general, it infects the maintenance leaves of tea which ensures the nourishment to the young shoots and tender foliage that ultimately results in huge crop loss (Joshi et al 2009, Horikawa 1986.…”

A b s t r a c t A r t i c l e I n f oThe grey blight, caused by Pestalotiopsis theae is a serious problem in almost all tea growing regions of India. A large number of tea cultivars were found to be susceptible to this disease. Evaluation of four selected fungicides (carbendazim 12% a.i + mancozeb 63% a.i., hexaconazole 5 EC, copper oxychloride 50 WP and copper hydroxide 77 WP) have been found effective in suppressing the pathogen to the considerable degree under in vitro conditions. Results indicated that, maximum control (70.8%) was achieved in the case of combi fungicidal formulation (carbendazim 12% a. i. + mancozeb 63% a. i.) followed by hexaconazole 5 EC and copper hydroxide 77 WP and copper oxychloride 50 WP, respectively. Effort has been made to evaluate the effectiveness of the indigenous Trichoderma viride (KBN-24) and T. asperellum (KBN-29) in inhibiting the mycelial growth of P. theae in dual culture method and the results indicated significant inhibition of the pathogen. Results on the compatibility study indicated that the tested fungicides adversely affected the growth of T. viride to varying degree. The maximum inhibition (79.0%) was noted in case of combi fungicide formulation followed by copper oxychloride (75.8%) and hexaconazole (70.4%). Thus the results of this current investigation highlighted the fact that the local Trichoderma isolates were found effective in controlling the targeted phytopathogen. However, use of such fungicides soon after the application of Trichoderma formulation, should be discouraged to have a better control of the disease.
