1. Plant to insect horizontal gene transfer: empowering whiteflies.

Horizontal gene transfer (HGT) is a well-documented evolutionary driving phenomenon in prokaryotes and eukaryotes, but its impact on the plant kingdom has remained elusive. A recent study provides compelling evidences, which support the idea that a plant-derived gene allows for the detoxification...

2. Correlation between protein secondary structure and mechanical performance for the ultra-tough dragline silk of Darwin's bark spider.

The spider major ampullate (MA) silk exhibits high tensile strength and extensibility and is typically a blend of MaSp1 and MaSp2 proteins with the latter comprising glycine-proline-glycine-glycine-X repeating motifs that promote extensibility and supercontraction. The MA silk from Darwin's bark...
