Aims: To characterize causal pathogen of Sansevieria trifasciata anthracnose through morphology and molecular analysis; to evaluate the host range of the pathogen; and to explicate the infection process by the pathogen histopathologically. Methods and Results: Symptomatic leaves of S. trifasciata were collected from five states in Malaysia. The causal pathogen was isolated and identified for the first time in Malaysia as C. sansevieriae based on morphological and multigene phylogenetic analyses using ITS, TUB2 and GAPDH sequences. Pathogenicity tests were conducted on different hosts. Colletotrichum sansevieriae was not pathogenic towards S. cylindrica, S. masoniana, Furcraea foetida, Chlorophytum comosum, Aloe vera and Gasteria carinata, confirming the exceptionally high host specificity for a species of Colletotrichum. Histopathology was performed using light microscope and scanning electron microscopy to study the infection process of C. sansevieriae on S. trifasciata. Colonization of host leaves by the pathogen was observed 2 days after inoculation. Conclusions: Colletotrichum sansevieriae caused anthracnose of S. trifasciata in Malaysia. It is a host-specific pathogen and colonized the host intracellularly. Significance and Impact of the Study: This is the first report of C. sansevieriae causing anthracnose of S. trifasciata in Malaysia. The host range test and understanding of the infection process will provide better understanding of the host-pathogen relationship and beneficial for effective disease management.

“…The amplification was carried out in a total volume of 50 μl PCR mixture as described by Kee et al (2017). The PCR reactions for TEF1-α and mtSSU were performed in a MyCycler™ Thermal Cycler (Bio-rad, Hercules, CA, USA) by following conditions as suggested by Kee et al (2019) and Laurence et al (2012), respectively. The PCR fragments were sent to a service provider for DNA purification and sequencing (First BASE Laboratories Sdn Bhd, Seri Kembangan, Malaysia).…”

Symptoms of fruit blotch were noticed on roselle (Hibiscus sabdariffa) in Relau, Penang and Karangan, Kedah. The aims of this study were to isolate and identify the suspected causal pathogen and to evaluate its pathogenicity towards the host. Two isolates of Fusarium sp. were isolated from the blotched fruits of H. sabdariffa and morphologically identified. Sequences analysis based on translation elongation factor (TEF1-α) and mitochondrial small subunit ribosomal DNA (mtSSU rDNA) showed that both isolates had 99.53% identity to AF333934 and 100% to AF333941, Fusarium concentricum. Phylogenetic analysis demonstrated that both isolates were in the same clade with the reference isolates of F. concentricum from GenBank, supported by 97% bootstrap value. The isolates were pathogenic toward H. sabdariffa, exhibiting typical blotch symptoms on the inoculated fruits. This is the first report of fruit blotch disease caused by F. concentricum on H. sabdariffa in Malaysia.

“…Sansevieria trifasciata was documented as the host of several fungal pathogens including Neoscytalidium dimidiatum , Stemphylium vesicarium , Lasiodiplodia spp. and Colletotrichum sansevieriae (Ahmadpour & Poursafar, 2018; Aldaoud, DeAlwis, Salib, Cunnington, & Doughty, 2011; Kee, Suhaimi, Zakaria, & Mohd, 2017; Kee et al, 2019). Besides, leaf spot of S. trifasciata was reported to be caused by several pathogens, namely C. neosansevieriae , Chaetomella and Stemphylium lycopersici (Crous et al, 2015; Kee, Zakaria, & Mohd, 2018; Li, Zhou, Lu, & Ye, 2013).…”

“…It was also one of the ethnomedicinal plants used by Orang Asli in the country to reduce pain and inflammation of the ear (Samuel et al, 2010). Sansevieria trifasciata is susceptible to different diseases such as leaf spot, leaf blight, anthracnose, rot and root knot (Crous et al, 2015; Kee, Zakaria, & Mohd, 2019; Misra, Misra, & Mishra, 2002; Nakamura, Ohzono, Iwai, & Arai, 2006; Takeuchi, Horie, & Nishimura, 2002). During a series of field surveys in September and November 2015, leaf spot disease caused by unknown pathogen was observed on S. trifasciata in Malaysia.…”

Leaf spot disease was detected on Sansevieria trifasciata in Malaysia. Two Curvularia species namely C. eragrostidis and C. asianensis were isolated as the pathogens. The isolated fungi were identified based on morphology and multigene phylogeny (ITS, GAPDH and TEF1‐α). Pathogenicity tests confirmed the roles of both Curvularia isolates in causing leaf spot of S. trifasciata. To our knowledge, this is the first report of C. eragrostidis and C. asianensis causing leaf spot of S. trifasciata in Malaysia.
