New shortcut speeds up building copies of plant-infecting viruses
Crop Improvement
The yellowing, curling leaves you might spot on tomatoes or cassava in a garden or farm plot are often caused by this exact family of viruses, and faster lab tools mean quicker progress toward resistant varieties.
Some plant viruses carry their genetic instructions as single-stranded DNA instead of the double-stranded kind most living things use. To study these viruses in the lab, scientists need to rebuild a working copy of the virus's genome and get it back into a plant, a process called making an agroinfectious clone. This paper describes a simpler one-step way to stitch that DNA together, which should let researchers study these plant diseases and search for resistant crop varieties more quickly.

Technical Summary
Scientists developed a faster, simpler lab method to build infectious copies of plant viruses that use single-stranded DNA, tools researchers need to study how these viruses cause disease and to test resistance in crops.
Plant signaling encompasses the molecular and cellular mechanisms by which plants perceive and respond to environmental changes, hormonal signals, and stress conditions. These signaling pathways regulate fundamental biological processes including growth, development, nutrient acquisition, and
