Abstract

Mesophyll chloroplasts from sodium-deficient compared to normal plants of the C(4) species Kochia childsii and Amaranthus tricolor were found to have significantly less stacking in their grana. On the other hand, no marked difference of thylakoid arrangement between bundle sheath chloroplasts from sodium-deficient and normal plants of A. tricolor were observed.
