Background: Arbuscular mycorrhizal (AM) fungi form a highly adaptable and versatile group of fungi found in natural and man-managed ecosystems. Effector secreted by AM fungi influence symbiotic relationship by modifying host cells, suppressing host defense and promoting infection to derive nutrients from the host. Here, we conducted a reference-based transcriptome sequencing of Funneliformis mosseae BR221 to enhance understanding on the molecular machinery involved in the establishment of interaction between host and AM fungi.

Systems Biology of Streptophyte Cell Evolution.

Annu Rev Plant Biol

January 2025

1Department of Applied Bioinformatics, Institute for Microbiology and Genetics, University of Göttingen, Göttingen, Germany; email:

More than 500 million years ago, a streptophyte algal population established a foothold on land and started terraforming Earth through an unprecedented radiation. This event is called plant terrestrialization and yielded the Embryophyta. Recent advancements in the field of plant evolutionary developmental biology (evo-devo) have propelled our knowledge of the closest algal relatives of land plants, the zygnematophytes, highlighting that several aspects of plant cell biology are shared between embryophytes and their sister lineage.

Inhibition of Interleukin-40 prevents multi-organ damage during sepsis by blocking NETosis.

Crit Care

January 2025

Center of Clinical Laboratory Medicine, Zhongda Hospital, Southeast University, Nanjing, Jiangsu, China.

Despite intensive clinical and scientific efforts, the mortality rate of sepsis remains high due to the lack of precise biomarkers for patient stratification and therapeutic guidance. Interleukin 40 (IL-40), a novel cytokine with immune regulatory functions in human diseases, was elevated at admission in two independent cohorts of patients with sepsis. High levels of secreted IL-40 in septic patients were positively correlated with PCT, CRP, lactate (LDH), and Sequential Organ Failure Assessment (SOFA) scores, in which IL-40 levels were used to stratify the early death of critically ill patients with sepsis.

Evolution of interorganismal strigolactone biosynthesis in seed plants.

Science

January 2025

Aiiso Yufeng Li Family Department of Chemical and Nano Engineering, University of California, San Diego, CA, USA.

Strigolactones (SLs) are methylbutenolide molecules derived from β-carotene through an intermediate carlactonoic acid (CLA). Canonical SLs act as signals to microbes and plants, whereas noncanonical SLs are primarily plant hormones. The cytochrome P450 CYP722C catalyzes a critical step, converting CLA to canonical SLs in most angiosperms.

Incorporation of animal-based foods into early hominin diets has been hypothesized to be a major catalyst of many important evolutionary events, including brain expansion. However, direct evidence of the onset and evolution of animal resource consumption in hominins remains elusive. The nitrogen-15 to nitrogen-14 ratio of collagen provides trophic information about individuals in modern and geologically recent ecosystems (<200,000 years ago), but diagenetic loss of this organic matter precludes studies of greater age.

The disruption of Cu homeostasis is associated with the pathogenesis of many diseases and can result in alterations in Cu isotope fractionation. Changes in the Cu isotope ratio (Cu/Cu) of body fluids and tissues have been observed in liver disorders, cancers, and other diseases, displaying diagnostic/prognostic potential. However, it is not entirely clear whether certain physiological or lifestyle factors may also influence the bodily Cu isotopic composition, potentially obfuscating the signature of the pathology.
