Multiple repetitive sequences of authentic genes commonly exist in fungal genomes. AT-biased genotypes of have been hypothesized as repetitive pseudogenes in the genome of (GC-biased Genotype #1 of ) and are generated through repeat-induced point mutation (RIP), which is charactered by cytosine-to-thymine and guanine-to-adenine transitions, concurrent epigenetic methylation, and dysfunctionality. This multilocus study examined repetitive sequences in the genome and transcriptome using a bioinformatic approach and revealed that 8.

Chinese cordyceps (GL) is a traditional medicinal fungus, with (, BL) and (, JSB) being fungi isolated from wild Chinese cordyceps. These three species share similar chemical composition and pharmacological effects. Existing studies have primarily compared the metabolites of Chinese cordyceps and , overlooking the assessment of antioxidant capacity in Chinese cordyceps, , and .

Article Synopsis
  • Sexual reproduction in ascomycetes is regulated by the mating-type (MAT) locus, and genetic studies have suggested a (pseudo)homothallic reproduction model, although findings show that male and female mating-type genes are differentially present and expressed.
  • The research indicates that reproduction is controlled at various biological levels, including genetic and transcriptional, with mutant mating proteins potentially exhibiting various secondary structures that affect function.
  • The data point to self-sterility in these fungi, highlighting the need for mating partners to achieve sexual reproduction, thus supporting hybridization models instead of self-fertilization in natural populations.

Article Synopsis
  • - The study focuses on bird's nest fungi, a group of mushrooms with medicinal properties in Chinese medicine, and conducts the first comprehensive analysis of their mitochondrial genomes (mitogenomes).
  • - Researchers analyzed five species with circular mitogenomes ranging in size, revealing both structural similarities within the family and genetic diversity across related groups.
  • - Phylogenetic analyses provided insights into evolutionary relationships and the genetic uniqueness of these fungi, contributing to a better understanding of fungal mitogenomes overall.

species are among the filamentous fungi with the most pronounced impact on agricultural production and human health. The mycotoxins produced by pathogenic not only attack various plants including crops, causing various plant diseases that lead to reduced yields and even death, but also penetrate into the food chain of humans and animals to cause food poisoning and consequent health hazards. Although sporadic studies have revealed some of the biosynthetic pathways of toxins, they are insufficient to satisfy the need for a comprehensive understanding of toxin production.

Objective: To examine multiple genotypes of Ophiocordyceps sinensis in a semi-quantitative manner in the stromal fertile portion (SFP) densely covered with numerous ascocarps and ascospores of natural Cordyceps sinensis and to outline the dynamic alterations of the coexisting O. sinensis genotypes in different developmental phases.

Methods: Mature Cordyceps sinensis specimens were harvested and continuously cultivated in our laboratory (altitude 2,254 m).

Phenyllactic acid (PLA) has been demonstrated to possess antibacterial activity and capacity to prolong food shelf life. However, studies on the performance of PLA in inhibiting Staphylococcus aureus and its effectiveness when applied to dairy products are largely lacking. Here, antibacterial activity (planktonic and biofilm states) of PLA against S.

Article Synopsis
  • Bacteriocins, like LSB1 derived from Lactobacillus plantarum, can inhibit foodborne pathogens, particularly Staphylococcus argenteus, which is linked to food poisoning.
  • LSB1 demonstrated a low minimum inhibitory concentration, strong stability under various conditions, and the ability to disrupt cell membranes of S. argenteus, leading to cell death.
  • This study highlights LSB1's potential as a natural antibacterial agent for food safety, specifically against S. argenteus in both its active and biofilm forms.

Staphylococcus aureus and its biofilm have emerged as a significant threat to the safety of dairy products. In recent years, lactic acid bacteria (LAB) bacteriocins have been widely acknowledged as the potential natural antibacterial substance in food biopreservation due to their excellent antibacterial effects. However, few LAB bacteriocins with antibacterial and antibiofilm activity against S.

Article Synopsis
  • A study investigated the effects of asexual endophytes and seed-borne fungi on seed growth by using supernatants from liquid cultures of the endophytes.
  • Over an 8-week greenhouse study, various concentrations of endophyte supernatants improved key growth metrics such as germination rate, coleoptile and radicle length, and seedling dry weight when under stress from fungi.
  • While there was no immediate increase in tiller numbers, significant growth improvements were noted later in the study, confirming that endophyte supernatants can effectively enhance seed germination and growth in controlled environments.

Article Synopsis
  • The study investigated the effectiveness and safety of ET-A receptor antagonists like zibotentan and atrasentan for treating castration-resistant prostate cancer (CRPC) through a meta-analysis of randomized controlled trials.
  • The analysis included data from eight trials with a total of 6,065 patients and found no significant improvement in progression-free survival (PFS), overall survival (OS), or adverse events (AEs) when using ET-A antagonists compared to placebo or when combined with docetaxel.
  • The conclusion emphasized that standard treatment for CRPC should still be single-agent docetaxel, as ET-A receptor antagonists did not show any significant advantages over current options.

Through researches of channels and collaterals and clinical practice of many years, the authors understand that Chinese medicine, which considers the human body as an interrelated, mutual constraints, whole, dynamic living system, has gradually become an important part of modern medicine. Channels and collaterals are a closed loop system which is communicated and linked by energy and information in the form of electromagnetic oscillation, reflecting many characteristics similar to quantum. Channels and collaterals are not a fixed organizational structure.
