Abstract:
... KEY MESSAGE: TaPGLP1, a chloroplast stromal 2-phosphoglycolate phosphatase of wheat, is an ATG8-interacting protein and undergoes autophagic degradation in starvation-treated wheat mesophyll protoplasts. Selective autophagy in plants has been shown to target diverse cellular cargoes including whole chloroplasts (Chlorophagy) and several chloroplast components (Piecemeal chlorophagy). Most cargoes ...

Abstract:
... Serial sectioning transmission electron microscopy (ssTEM) is a classical method of 3D reconstruction using serial sections obtained with an ultramicrotome. However, producing a long ribbon with homogeneity is difficult. Here, ultramicrotome movement was suspended after producing a ribbon of 15–30 serial sections (cutting intervals, 100 nm), and then, the ribbon was mounted on an individual one-sl ...

Abstract:
... Microphylls, simple leaves with a single vein and no leaf gap, are the typical lycophyte leaves. However, Selaginella schaffneri has complex veins. Structural features and phylogeny associated with this unusual venation have remained unknown. We studied the leaf, venation, spore structures, and phylogeny of S. schaffneri, with S. erythropus as a typical Selaginella for comparison. Leaf veins of bo ...
