Use of argA-lac fusions to generate lambda argA-lac bacteriophages and to determine the direction of argA transcription in Escherichia coli [PDF]
Journal of Bacteriology, 1977 Fusions of lac genes to the argA operator were constructed, and lambda phages carrying these fusions were isolated and characterized. With the aid of a lambda phage carrying an argA-lac fusion, the direction of argA transcription on the Escherichia coli chromosome was determined to be clockwise.

Ecosphere, Volume 17, Issue 5, May 2026.Abstract Rodent population cycles are observed in highly seasonal environments. As most rodents are herbivorous, the availability and the quality of their food resources vary greatly across seasons. Furthermore, it is well documented that herbivore densities have a measurable effect on vegetation and, conversely, that vegetation dynamics can influence ...

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments
Environmental DNA, Volume 8, Issue 3, May–June 2026.We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...
