[Antenna form of chlorophyll of photosystem II in chloroplasts].

Low temperature fluorescence spectra and second derivatives of chlorophyll absorption spectra in leaves, chloroplasts of mesophyll and parenchyme bundle sheath cells (BSC) were studied. It has been shown that in ontogenesis of BSC chloroplasts of Zea mays leaves along with a decrease of the activity of the PS-2 and a reduction of granal regions the fluorescence maximum of chlorophyll decreases at 695 nm. The change of this fluorescence band is concerned with the disturbance of the form of chlorophyll "a" absorbing at 684 nm and performing the function of an antenna of the pigment-protein complex of PS-2. Similarities in the distribution of chlorophyll forms between three pigment-protein complexes of chloroplast membranes in green algae and higher plants are discussed.
