Fig. 1. Localization of MoHTR1 and MoHTR2 in rice nuclei.

Differential interference contrast (DIC) and confocal images of rice sheath cells infected by M. oryzae at 30 hours post-inoculation (hpi). The fluorescent images shown were chosen from confocal optical z-sections taken at 1-μm intervals. Both a MoHTR1:mRFP and b MoHTR2:mRFP were co-localized with PWL2:eGFP:NLS, a maker used to label rice nuclei (arrow). Arrowheads indicate biotrophic interfacial complexes of invading M. oryzae. Scale bars = 10 μm. Representative micrographs are shown from three independently infected rice sheaths and additional representative data are provided as a Source Data file.
