Colored autoradiographs of Vigna species fed with radioactive Na (²²Na), indicating Na⁺ allocation in plant bodies. While the salt-sensitive species V. angularis (azuki bean, left) shows Na⁺ allocation to the stem and the leaves, the salt-tolerant species, V. nakashimae, V. riukiuensis, V. luteola and V. marina show different patterns of Na⁺ allocation. In this issue, by tracer analysis and mass spectrometry, Noda et al. revealed the diversity of the mechanisms of salt tolerance in the wild genetic resources of the genus Vigna (This issue, p. 326–331).
