Fig. 3.

Arabidopsis expressing Zmetr2b or Zmers1b exhibit a larger leaf size and a delay in senescence. The same lines used in Fig. 1 were grown under 100 μmol m⁻² s⁻¹ for 4 (A) or 7 (B) weeks. Wild-type (WT) plants were included as an ethylene sensitive control. ein2-5 and etr1-1 were included as ethylene insensitive controls. In (C), the size of leaf 6 from 4 week-old plants is compared for each line
