Chloroplasts are usually considered spheroid organelles, but this is not the only shape of chloroplasts. The chloroplast of Chlamydomonas has been typically described as cup-shaped. However, in old studies, it was also modeled as a complex shape with “perforations” or windows. Here, we reconstructed the cellular architecture of Chlamydomonas reinhardtii and C. applanata using an array tomography system installed on a field emi...

This research provides insight into a unique salt tolerance mechanism of Vigna riukiuensis . V. riukiuensis is one of the salt-tolerant species identified from the genus Vigna . We have previously reported that V. riukiuensis accumulates a higher amount of sodium in the leaves, whereas V. nakashimae , a close relative of V. riukiuensis , suppresses sodium allocation to the leaves. We first suspected that V. riukiuensis would h...
