Immunofluorescence labelling with JIM5 and JIM7 of hand-cut transverse sections of maize ( ‘Nongda3138’, Al-resistant) root apex subjected to 0·5 mm CaCl₂ solution (pH 4·5) either with 0 or 50 µm LaCl₃ for 24 h. Root sections were taken from 2 mm behind the apex. The images are representative of at least ten replicate roots for each treatment. Scale bars = 50 µm, for all images.
