Novel heat shock response mechanism mediated by the initiation nucleotide of transcription.

Among SigA-dependent promoters in Bacillus subtilis, we compared the nucleotide sequences of heat shock responding and non-responding promoters. Chimeric promoter experiments revealed that the heat shock response could be ascribed to the initiation nucleotide (iNTP) of the transcription. Our in vivo reporter assay results indicated that a full response was achieved using GTP, a reduced response was observed using ATP, and no additional expression was observed using UTP or CTP.

Repurposing a traditional Japanese method of pest control for wintering pine moths, Komo-trap, for use against summer and winter populations of fall webworms.

Background: The fall webworm, Drury (Lepidoptera: Erebidae), is a widespread invasive species. It is native to North America, ranging from southern Canada to northern Mexico. During and after the 1940s, this pest was accidentally introduced in many parts of Europe and Asia.
