Sod culture (SC) and conventional agriculture (CA) represent two distinct field management approaches utilized in the cultivation of tea plants in Taiwan. In this study, we employed gas exchange and chlorophyll fluorescence techniques to assess the impact of SC and CA methods on the photosynthetic machinery of Camellia sinensis cv. TTES No.

, 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.

Wolbachia is a ubiquitous endosymbiotic bacterium that manipulates insect reproduction. A notable feature of Wolbachia is male killing (MK), whereby sons of infected females are killed during development; however, the evolutionary processes by which Wolbachia acquired the MK ability remain unclear. The tea tortrix moth Homona magnanima (Tortricidae) harbours three non-MK Wolbachia strains (wHm-a, wHm-b and wHm-c) and an MK strain wHm-t.

Article Synopsis
  • Some endosymbionts cause male killing, where infected females produce few or no male offspring due to unknown mechanisms.
  • In this research, a specific 76 kbp prophage region linked to male-killing was identified in a moth, revealing genes that affect male and female offspring development.
  • The study showed that certain gene expressions led to high male mortality rates, while combinations of these genes highlighted complex interactions in male lethality, shedding light on the evolution of male-killing among insects and the role of bacteriophages in this process.

Male killing (MK) is a type of reproductive manipulation induced by microbes, where sons of infected mothers are killed during development. MK is a strategy that enhances the fitness of the microbes, and the underlying mechanisms and the process of their evolution have attracted substantial attention. Homona magnanima, a moth, harbors two embryonic MK bacteria, namely, () and (), and a larval MK virus, Osugoroshi virus (OGV; Partitiviridae).

Article Synopsis
  • Castor cake, a by-product of castor oil extraction, is commonly used as an organic fertilizer but can release the toxic alkaloid ricinine into the soil, raising food safety and health concerns.
  • A study conducted soil pot experiments to analyze the release and metabolism of ricinine after applying different amounts of castor cake, discovering significant variations in ricinine concentration over time.
  • The research developed new methods for quantifying ricinine and identifying its metabolites in soil pore water, revealing that ricinine undergoes several metabolic transformations, including demethylation and hydroxylation, once it is in the soil environment.

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.

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.

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.

Wolbachia are inherited intracellular bacteria that cause male-specific death in some arthropods, called male-killing. To date, three Wolbachia strains have been identified in the oriental tea tortrix Homona magnanima (Tortricidae, Lepidoptera); however, none of these caused male-killing in the Japanese population. Here, we describe a male-killing Wolbachia strain in Taiwanese H.
