mRNA expression of a cadmium-responsive gene is a sensitive biomarker of cadmium exposure in the soil collembolan Folsomia candida.
The gene expression of environmental organisms is useful as a biomarker of environmental pollution. One of its advantages is high sensitivity. We identified the cDNA of a novel cadmium-responsiveExpand

Radiocesium immobilization to leaf litter by fungi during first-year decomposition in a deciduous forest in Fukushima.
Vast forest areas in eastern Japan have been contaminated with radio-isotopes by the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. Radiocesium (radioCs) is known to remain bioavailable inExpand

A quantitative protocol for DNA metabarcoding of springtails (Collembola).
We developed a novel protocol with superior quantitative analysis results for DNA metabarcoding of Collembola, a major soil microarthropod order. Degenerate PCR primers were designed for conservedExpand

Defensive role of cystidia against Collembola in the basidiomycetes Russula bella and Strobilurus ohshimae.
Cystidia in fruit bodies are taxonomically important characters. However, little is known about their ecological functions. The defensive role of cystidia against the collembolans CeratophysellaExpand
