The earliest recorded plant virus disease: pathogenic DNA paints summer foliage gold, and inspired a poet over a millennium ago
Article Abstract:
Eupatorium plants in Japan frequently exhibit a striking yellow pattern on their leaves during summer3 due to the presence of a gemini-virus named eupatorium yellow-vein virus (EpYVV)4. It was suspected that the plants might be further infected with a DNA beta-satellite component, hence their infectivity was tested, the experiment for which has been detailed.

Human DNA ligase I completely encircles and partially unwinds nicked DNA
Article Abstract:
The crystal structure of human DNA ligase I in complex with a nicked, 5' adenylated DNA intermediate is reported. The structure shows that the enzyme redirects the path of the double helix to expose the nick termini for the strand-joining reaction.
