Transcript accumulation of CsRALF4 at transmitting tract of unpollinated WT and Csalc ovaries by in situ hybridization. h’ are enlargements of red boxes in (h). Red arrows indicate transcript signals at lateral- and terminal-TTs in WT before pollination, and blue arrows refer to the weakened transcript signals at lateral- and terminal-TTs in Csalc mutants. Scale bars = 500 μm. The experiment was repeated three times with similar results.
