Species classified in () include multiple entomopathogenic fungi. Numerous changes have recently occurred in the nomenclature of cordycipitaceous fungi due to the single naming system proposed for pleomorphic fungi in 2011. Species of are widely applied as herbal medicines, especially in Asian cultures.

Article Synopsis
  • Oats are a minor forage crop in Taiwan, and previous records of oat rust disease in the country are limited, leading to a lack of understanding of the pathogen population.
  • In 2019, a rust-like outbreak at National Taiwan University's Experimental Farm prompted researchers to collect samples and identify the responsible pathogen, suspected to be the oat crown rust fungus.
  • The study successfully confirmed the pathogen's identity using phenotypic and molecular techniques, establishing it as the first molecular confirmation of this pathogen in Taiwan and noting its low virulence traits.

Unlabelled: This study investigates the effects of selected PGPB on lettuce growth performance under heat-stress conditions. Bacterial plant growth-promoting potentials have been characterized and identified successfully in ongoing studies. Based on in vitro plant growth-promoting potential, the top five bacteria were ranked and identified as sp.

, commonly referred to as pestalotiopsis-like fungi, exhibit a broad distribution and are frequently found as endophytes, saprobes and pathogens across various plant hosts. The taxa within pestalotiopsis-like fungi are classified into three genera viz. , and , based on the conidial colour of their median cells and multi-locus molecular phylogenies.

Leaves of Welsh onion () are subject to various fungal diseases such as anthracnose ( species) and Stemphylium leaf blight (). These diseases are the main biotic limitations to Welsh onion production in northern Taiwan. From 2018 to 2020, anthracnose symptoms were observed throughout Welsh onion fields in northern Taiwan, mainly the Sanxing area.

Foliar diseases caused by and species are among the major biotic factors limiting Welsh onion production in Taiwan. Owing to concerns about the environment and the development of pathogen resistance to existing fungicides, biological control using endophytes is emerging as an eco-friendly alternative to chemical control. The aim of the present study was to isolate endophytes from healthy Welsh onion leaves and investigate their antagonistic potential against the major phytopathogenic fungi associated with Welsh onion plants in Taiwan.

Article Synopsis
  • * Researchers identified three fungal species linked to brown blight, with one being a first report in Taiwan, and determined optimal temperatures for their growth, noting that one species was particularly pathogenic.
  • * The study emphasized that wounds on tea leaves lead to more severe disease outcomes, and suggested that preventative fungicide applications after pruning could help manage the disease effectively.

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family . Thus, an alternate hypothesis, namely a very broad concept of the genus was proposed. In doing so, however, a significant body of data that supports distinct genera in based on morphology, biology, and phylogeny is disregarded.

is one of the major crops grown in Taiwan and has been widely cultivated around the island. Tea leaves are prone to various fungal infections, and leaf spot is considered one of the major diseases in Taiwan tea fields. As part of a survey on fungal species causing leaf spots on tea leaves in Taiwan, 19 fungal strains morphologically similar to the genus were collected.

The identification and proper naming of microfungi, in particular plant, animal and human pathogens, remains challenging. Molecular identification is becoming the default approach for many fungal groups, and environmental metabarcoding is contributing an increasing amount of sequence data documenting fungal diversity on a global scale. This includes lineages represented only by sequence data.

For the past 30 years, the most predominant strawberry cultivar in Taiwan has been 'Taoyuan No. 1', which produces fruit with rich flavor and aroma but is highly susceptible to anthracnose (Chung et al. 2019).

Strawberry is a small fruit crop with high economic value. Anthracnose caused by Colletotrichum spp. poses a serious threat to strawberry production, particularly in warm and humid climates, but knowledge of pathogen populations in tropical and subtropical regions is limited.

Pleosporales species are important plant pathogens, saprobes, and endophytes on a wide range of economically important plant hosts. The classification of Pleosporales has undergone various modifications in recent years due to the addition of many families described from multiple habitats with a high level of morphological deviation. Numerous asexual genera have been described in Pleosporales that can be either hyphomyceteous or coelomycetous.

Article Synopsis
  • Fungi are a huge group of organisms with about 3 million predicted species, making them the second largest after plants and animals, but they can be tricky to identify due to their simple and sometimes confusing body structures.
  • To identify fungi better, scientists suggest using a combination of different methods, including their genetic history and physical traits, instead of just one method.
  • There are challenges with DNA barcoding for fungi because no single method works for all types, so researchers need to be careful and improve how they document and categorize these organisms to get accurate results.

The order Pleosporales comprises a miscellaneous group of fungi and is considered to be the largest order of the class Dothideomycetes. The circumscription of Pleosporales has undergone numerous changes in recent years due to the addition of large numbers of families reported from various habitats and with a large amount of morphological variation. Many asexual genera have been reported in Pleosporales and can be either hyphomycetes or coelomycetes.

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification.

DNA phylogenetic comparisons have shown that morphology-based species recognition often underestimates fungal diversity. Therefore, the need for accurate DNA sequence data, tied to both correct taxonomic names and clearly annotated specimen data, has never been greater. Furthermore, the growing number of molecular ecology and microbiome projects using high-throughput sequencing require fast and effective methods for en masse species assignments.
