Direct cloning method CAPTUREs novel microbial natural products

Microorganisms possess natural product biosynthetic gene clusters (BGCs) that may harbor unique bioactivities for use in drug development and agricultural applications. However, many uncharacterized microbial BGCs remain inaccessible. Researchers previously demonstrated a technique using transcription factor decoys to activate large, silent BGCs in bacteria to aid in natural product discovery.

The hidden dance of roots revealed

New time-lapse videos capture something that's too slow for our eyes to see: the growing tips of plant roots make corkscrew-like motions, waggling and winding in a helical path as they burrow into the soil. By using time-lapse footage, along with a root-like robot to test ideas, researchers have gained new insights into how and why rice root tips twirl as they grow.
