3. Aerenchyma formation in soybean

Six decades ago, Arikado (1954) reported that wild soybean, the ancestor of today’s cultivated soybean, produced a conspicuous aerenchymatous phellem that differentiated from the phellogen in the stems, hypocotyls, adventitious roots, and nodules of this species when the plants were exposed to flooded soil 16 days after sowing. In addition, studies based on a single cultivar “Shirodaizu” suggest that cultivated soybean has a low ability to develop aerenchyma in its stems, roots, and nodules under flooding. However, it has been reported that secondary aerenchyma covers the soybean nodule surface in flooded soils (Pankhurst and Sprent, 1975) and under hypoxic rhizosphere conditions (Parsons and Day, 1990), and is an obvious change compared with the morphology under non-flooded or non-hypoxic conditions.
