Amyloplast accumulation and in situ localization of leghemoglobin transcripts in nodules of wild-type and crinkle plants. A, Central zone of wild-type mature nodule with many infected cells. Few amyloplasts are present in the uninfected cells. B, Type II nodule of crinkle with some infected cells and with heavy accumulation of amyloplasts; C and D, longitudinal sections hybridized with antisense RNA probes showing leghemoglobin expression in the infected cells of wild type and crinkle, respectively. Arrows, Amyloplasts; ic, infected cells; uc, uninfected cells. Bars in A and B = 50 μm; and in C and D = 100 μm.
