The Journal of Experimental Botany is publishing a good collection of review articles on auxin. Topics include ARF transcription factors, Auxin’s role in lateral root formation, Auxin research in rice and implications for crop improvement, Integration of multiple auxin signaling pathways, Evolution of auxin signaling, Auxin homeostasis, and Auxin, microtubules, and vesicle trafficking. As you know, auxin apparently is involved in everything, so it’s always a good time to refresh your understanding about this important hormone. J. Exp. Bot.
