Objectives: To develop an innovative magnetic resonance imaging (MRI)-based PUMCH (Peking Union Medical College Hospital) classification system aimed at standardising the diagnosis of congenital cervical malformations (CCMs) by identifying their distinctive MRI features.
Methods: Seventy-nine consecutive patients with CCM underwent pre-treatment pelvic MRI; three experienced gynaecological radiologists retrospectively analysed these images. Qualitative assessments included Rock et al's classification; PUMCH classification; haematometra; cervical signal features; ovarian endometriosis; haematosalpinx; and uterine, vaginal, urinary, and musculoskeletal malformations.
Dark septate endophytes (DSEs) are the typical representatives of root endophytic fungi in heavy metal (HM)-contaminated environments. However, little is known about their roles in the HMs tolerance of hosts and the underlying mechanism. Here, we investigated the biological roles and molecular mechanisms of a DSE strain Falciphora oryzae in alleviating cadmium (Cd) toxicities in rice.

- The study explored the mutualism between the dark septate endophyte Harpophora oryzae and rice, focusing on its ability to combat rice blast disease caused by Magnaporthe oryzae.
- H. oryzae colonized rice roots predominantly in the differentiation zone, utilizing a biotrophic strategy that involved programmed cell death in the host.
- The fungus induced a systemic resistance in rice against M. oryzae through the activation of the OsWRKY45-dependent salicylic acid signaling pathway, enhancing the plant's antioxidative capacity and local protective responses.
Article Synopsis
- Microbial-derived volatiles are common in the environment and play key roles in communication between organisms; endophytes that produce these volatiles are gaining interest for their antibiotic properties and potential to create substances similar to those found in petroleum.
- These findings have promising implications for sustainable practices in agriculture, forestry, and industry, particularly in managing postharvest fruit diseases and producing biofuels.
- The review emphasizes the need for more research on the ecological roles of these volatile-producing endophytes and discusses the challenges and advances in bringing their products to market.
Ecological niches in the rhizosphere and phyllosphere of grasses capable of sustaining endophytes have been extensively studied. In contrast, little information regarding the identity and functions of endophytic fungi in stems is available. In this study, we investigated the taxonomic affinities, diversity, and host specificities of culturable endophytes in stems of wild rice (Oryza granulata) in China.

In this study, an integrative culture system was designed to capture a rich fungal consortium from the conifer Abies beshanzuensis. Results indicate an impressive diversity of fungal lineages (a total of 84 taxa classified in Dikarya) and a relatively high proportion of hitherto unknown species (27.

- Muscodor is a fungal genus originally defined by Muscodor albus, known for its antimicrobial volatile organic compounds (VOCs) that can serve as mycofumigants.
- Researchers discovered a new species of Muscodor from endophytic fungal strains found in various trees in Southeast China.
- The new strains show distinct characteristics, including growth at 25°C and unique antimicrobial VOCs, differing from other known Muscodor species, supported by phylogenetic analysis indicating they belong to the same taxon.
A survey of the endophytic fungal community of wild rice (Oryza granulata) in China was conducted. Two isolates recovered from healthy roots are assumed to be dark septate endophytes (DSEs). They are morphologically similar to species from the genus Harpophora and are identified as a new species, Harpophora oryzae, based on the molecular phylogeny and morphological characteristics.

- Rice is a crucial global food crop, yet there is limited knowledge about the endophytic fungi associated with wild rice (Oryza granulate) in China.
- Through microscopy, cultivation, and PCR techniques, researchers identified a high diversity of fungal species, revealing 58 isolates with a significant proportion likely representing undescribed species.
- The study highlights distinct fungal communities through different analytical methods, suggesting a complex fungal consortium in wild rice roots that may have potential for mutualistic plant-fungal interactions.
