Fig. 1From: Establishment and optimization of mRNA in situ hybridization system in turnip (Brassica rapa var. rapa)Signal and tissue morphology of CLV3 mRNA by in situ hybridization with different fixatives. Fixing with FAA for 12 h at 4 °C lead to strong hybridized signal and integrated morphology a antisense, b sense. Fixing with 4% paraformaldehyde for 12 h at 4 °C lead to integrated morphology but weak signal intensity c antisense, d sense. Arrow, hybridized signal was found in the meristem of turnipBack to article page
