Extended Data Fig. 9: Functional analysis of MpICE1 and MpICE2 in A. thaliana mutants.

a, Confocal images of A. thaliana abaxial cotyledons of wild type (Ws-4), ice1-2 scrm2-1, and _proAtMUTE:MpSETA mute-2 expressing MpICE2 at 9 DAS. Arrowheads and asterisks indicate stomata and hydathode pores, respectively. The experiments were performed once. b, Confocal images of A. thaliana abaxial leaves of wild type (Col-0), ice1-2 scrm2-1, _proAtICE1:MpICE1 ice1-2 scrm2-1, and _proAtICE1:MpICE2 ice1-2 scrm2-1 at 13 DAS. The experiments were repeated three times with similar results. Bars, 100 µm.
