Abstract

A complex network makes simple pores Stomata, the pores found on the surface of plant leaves, form at intervals from stem cells. Development of stomata is controlled by the SPEECHLESS transcription factor. Lau et al. surveyed the genes that SPEECHLESS itself controls. Targets include genes involved in hormone signaling, control of cell proliferation, and the specification of asymmetric cell fates. Despite the apparent simplicity of a single pore, the genetic network that generates that pore is anything but simple. Science , this issue p. 1605
