Post-feeding and -injection Dynamics of dsRNA in 4 Insects

The variability of dsRNA-induced RNA interference is well documented with some insects very amenable to this method of regulating gene expression while are others are very much less so. The factors involved in this variation are known to some extent […]

GFP

An Orange Fluorescent Protein Excitable With Cyan Light – Like GFP

Chu et al report on in Nature Biotechnology on their creation of an orange fluorescent protein that can be excited using the same wavelengths used to excite GFP, providing new opportunities for conducting multiplexed epifluorescence microscopy studies. Fluorescent proteins are […]

Promoters From Two Sap-Sucking Pests

Qian et al (2016) using bioinformatic and transient heterologous expression systems have identified three strong promoters from the genomes of the Hemipterans  Nilaparvata lugens and Nephotettix cincticeps. The abundance of genome sequence data is a boon to insect science and […]

Six Tandem Cherries -> Very Bright Insects

Insect genetic modification technologies rely heavily on the use of fluorescent proteins as genetic markers, expression reporters etc. Colors vary, as do fluorescent outputs. Shearin et al. (2014) describe their efforts to increase signals from two popular fluorescent proteins, EGFP […]
