For regulatory networks we show how the concepts of informative nodes (Mochizuki) and determining nodes (Foias, Temam) coincide with the notion of feedback vertex sets from graph theory. As a consequence we can determine, and control, the long-time dynamics of networks from observations on a feedback vertex set, only. Examples include early Ascidian embryogenesis and genetic circadian clocks in mammals. The results are joint work with Atsushi Mochizuki, Gen Kurosawa, and Daisuke Saito (RIKEN, Wako).
