“…Different studies have indicated that some Neopestalotiopsis and Pestalotiopsis species have been isolated from healthy and dead tissues and reported as endophytic fungi. Several Pestalotiopsis species have been isolated as endophytes, but have been reported as pathogens in various hosts and in different regions ( Moslemi and Taylor 2015 ; Nozawa et al 2019 ; Wang et al 2019 ; Chen et al 2021 ; Jiang et al 2021 ). This suggests that some species may have interchangeable lifestyles such as endophytes, pathogens and saprobes within the same host.…”

Chinese yew, Taxus chinensis var. mairei is an endangered shrub native to south-eastern China and is widely known for its medicinal value. The increased cultivation of Chinese yew has increased the incidence of various fungal diseases. In this study, Pestalotioid fungi associated with needle spot of Chinese yew were isolated from Guangxi Province. Based on morphological examinations and multi-locus (ITS, tub2, tef-1α) phylogenies, these isolates were identified to five species, including two new species, Pestalotiopsis taxicola and P. multicolor, two potential novel Neopestalotiopsis species, Neopestalotiopsis sp. 3 and Neopestalotiopsis sp. 4, with a known Pestalotiopsis species (Pestalotiopsis trachycarpicola), firstly recorded from Chinese yew. These two new Pestalotiopsis species were morphologically and phylogenetically distinct from the extant Pestalotioid species in Chinese yew. Pathogenicity and culture characteristic tests of these five Pestalotioid species were also performed in this study. The pathogenicity test results revealed that Neopestalotiopsis sp. 3 can cause diseases in Chinese yew needles. These results have indicated that the diversity of Pestalotioid species associated with Chinese yew was greater than previously determined and provided helpful information for Chinese yew disease diagnosis and management.

“…Pestalotiopsis chamaeropis was found as an endophyte from an important medicinal plant here. However, it was reported as a serious phytopathogen in different countries ( 34 , 49 – 51 , 53 – 56 ). Pestalotiopsis photiniae was reported as an endophytic fungus on the branches of Roystonea regia , and it also has been isolated from the diseased leaves of blueberries ( 61 , 62 ).…”

“…Previous studies showed that a single ITS gene could be used to identify Pestalotiopsis microspora in H. brasiliensis (Kusdiana et al 2020), Oil Palm (Ismail et al 2017, and Adenium obesum (Jesus et al 2022). The combination of ITS, β-tubulin, and tef1 gene regions was reported to be a better taxonomic marker for Pestalotiopsis than a single gene (Maharachchikumbura et al 2016;Chen et al 2020;Das et al 2021;Aliya et al 2022a;Fiorenza et al 2022;Nozawa et al 2022).…”

Abstract. Darojat MR, Ardhie SW, Oktavia F, Sudarsono. 2023. New leaf fall disease in rubber-pathogen characterization and rubber clone resistance evaluation using detached leaf assay. Biodiversitas 24: 1935-1945. Leaf fall disease (LFD) has become a significant issue for rubber plantations worldwide. Over the last four years, a newly emerging LFD has posed an alarming problem in natural rubber production. The most efficient way to control LFD is to use resistance rubber clones. Therefore, this study aims to characterize the pathogen causing the newly emerging LFD and evaluate rubber clone resistance to the pathogen using detached-leaf assay. The fungal pathogens were isolated from 32 F1 progenies of PB 260 x SP 217 crosses, and the fungi were characterized and identified based on their morphological and molecular characteristics. The results showed that the isolated pathogen causing LFD was Neopestalotiopsis sp. Although they were all pathogenic, the arrays of isolated fungi exhibited various degrees of virulence, and P-212 was the most virulent fungal isolate. The resistance evaluation showed that rubber clones, isolates, and rubber clones by isolate interactions had a significant (p<0.05) effect on the lesion-symptom diameters. Based on the lesion diameter responses, the IRR 112 and RRIC 100 rubber clones were resistant to Pestalotiopsis sp. since they only showed less than 10 mm lesion diameters. The IRR 39 and PB 260 rubber clones were susceptible and showed more than 20 mm lesion diameters. The detached-leaf assay can easily screen rubber clones' responses to the fungi causing LFD. The resistance evaluation results can assist future rubber breeding strategies for the newly emerged LFD-resistant characters.
