Climate change and wood formation
Rising temperatures since the late 1970s have increased aridity in many regions of the globe, exposing semi-arid forests to additional stress.

Control of adventitious rooting and xylogenesis in arabidopsis
A study of Arabidopsis transcription factors finds that AR-formation and xylogenesis are inversely related but involve fine-tuning by the same proteins.

Aphid repellence in arabidopsis over-expressing FPS2
Plant-synthesized sesquiterpenes play a pivotal role in chemotactic interactions with insects. In Arabidopsis thaliana, FPS2 is involved in the synthesis of cytosolic FDP, a precursor
