Phyllosticta ophiopogonis sp. nov. from Ophiopogon japonicus (Liliaceae)

Abstract

A leaf spotting disease of an ornamental variety of Ophiopogon japonicus was discovered at several locations in northern Thailand. In all cases a species of Phyllosticta was associated with the lesions. Phyllosticta ophiopogonis sp. nov. is distinguished from Phyllosticta species from Liliaceae in conidia size, mucilaginous sheath and appendage thus the species is introduced as new in this paper. The new species which causes unsightly lesions on this ornamental plant is described, illustrated and compared with other similar Phyllosticta species.

“…The genus was revised by Van der Aa and Vanev (2002) and they accepted 141 species. The currently used generic circumscription of Phyllosticta is: "pycnidia globose, subglobose or tympaniform, conidiogenous cells holoblastic, with percurrent proliferation, conidia hyaline, 1-celled, ovoid, overate, ellipsoid, short cylindrical, or globose to subglobose, usually bearing a slime layer and an apical appendage" ( (Motohashi et al 2008;Wulandari et al 2009Wulandari et al , 2010Glienke et al 2011;Wang et al 2012;Su and Cai 2012;Wong et al 2012;Wikee et al 2012Wikee et al , 2013cZhang et al 2013b;Shivas et al 2013b), with the currently accepted species possibly being more than 171. Unfortunately, molecular data are currently available for about only 69 species (Table 18).…”

“…However following phylogenetic analysis, Wikee et al (2013c) placed this genus in Phyllostictaceae which is sister to the Botryosphaeriaceae. Phyllosticta species are known to cause leaf spots and various fruit diseases worldwide on a diverse range of hosts including some economically important crops and ornamentals such as citrus, banana, apple, grapes, cranberry, orchids, mai dong and maple (Uchida and Aragaki 1980;Paul and Blackburn 1986;Baayen et al 2002;McManus 1998;Olatinwo et al 2003;Paul et al 2005;Liu et al 2009b;Wikee et al 2011Wikee et al , 2012Shivas et al 2013b). Some species such as P. capitalensis are endophytes and weak pathogens (Baayen et al 2002;Glienke et al 2011;Wikee et al 2013a), while others such as P. cocoicola are saprobes (Punithalingam 1974;Taylor and Hyde 2003).…”

Polyphasic characterization of four new plant pathogenic Phyllosticta species from China, Japan, and the United States

“…Phyllosticta is an important plant pathogenic genus known to cause leaf spots and fruit diseases worldwide on many important economic plants and ornamentals such as citrus, banana, apple, grapes, cranberry, orchids, Ophiopogon sp., and guger tree (Engelman 1861;Ellis 1880;McManus 1998;Baayen et al 2002;Olatinwo et al 2003;Paul et al 2005;Wikee et al 2011;Su & Cai 2012;Wang et al 2012;Wikee et al 2012;Wong et al 2012;Shivas et al 2013;Zhang et al 2013b). Several Phyllosticta species are also known as endophytes and saprobes, e.g., Phyllosticta capitalensis and Phyllosticta cocoicola, respectively (Punithalingam 1974;Baayen et al 2002;Taylor & Hyde 2003;Glienke et al 2011;Wikee et al 2013a).…”

The occurrence of leaf blight on Ophiopogon japonicus caused by Phyllosticta ophiopogonis in Korea

“…caused a leaf spotting disease on mondo grass from Thailand, and was re-identified and reported as P. ophiopogonis sp. nov. based on symptoms and comparison of mycological characteristics with other Phyllosticta species described from Liliaceae (Wikee et al 2012). Leaf blight caused by P. ophiopogonis has not been reported previously in Korea (The Korean Society of Plant Pathology 2009).…”

“…In phylogenetic analysis, ITS sequences of Phyllosticta strains were included as reference sequences (Wikee et al 2013) and Botryosphaeria obtusa (GenBank Accession No. AY972105) was used as an outgroup (Wang et al 2012;Wikee et al 2012). The fungal isolate from mondo grass grouped with a clade in the phylogenetic tree comprising reference strains of Phyllosticta (Fig.…”
