High salt stress induces swollen prothylakoids in dark-grown wheat and alters both prolamellar body transformation and reformation after irradiation
High salinity causes ion imbalance and osmotic stress in plants. Leaf sections from 8-d-old
dark-grown wheat (Triticum aestivum cv. Giza 168) were exposed to high salt stress (600
mM) and the native arrangements of plastid pigments together with the ultrastructure of the
plastids were studied using low-temperature fluorescence spectroscopy and transmission
electron microscopy. Although plastids from salt-treated leaves had highly swollen
prothylakoids (PTs) the prolamellar bodies (PLBs) were regular. Accordingly, a slight …
