Plant development. Integration of growth and patterning during vascular tissue formation in Arabidopsis.

Science 2014 Aug;345(6197):1255215

Laboratory of Biochemistry, Wageningen University, Dreijenlaan 3, 6703HA Wageningen, the Netherlands.

Coordination of cell division and pattern formation is central to tissue and organ development, particularly in plants where walls prevent cell migration. Auxin and cytokinin are both critical for division and patterning, but it is unknown how these hormones converge upon tissue development. We identify a genetic network that reinforces an early embryonic bias in auxin distribution to create a local, nonresponding cytokinin source within the root vascular tissue. Read More
