 Title    Distribution of cis-iraws-ß-Carotene in Pigment-Protein Fractions of Photosystem I and II  
 Abstract    The distribution of isomers of ß-carotene is reported in the CP-47 pigment-protein complex of photosystem II and photosystem I (PS I) from barley. The distribution of carotenoids from light harvester complex II is reported. CP-47 lacks 9,9'-rá-carotene, but contains 9,13'-c/s-carotene; PS I lacks 9,\2>'-cis but contains 9,9'-eis. More 9-eis, 9,13-cw, 9,15-c/s, and epoxide is observed in CP-47 than in PS I.

 Title    Inhibition of State Transition and Light-Harvesting Complex II Phosphorylation-Mediated Changes in Excitation Energy Distribution in the Thylakoids of SANDOZ 9785-Treated Plants  
 Abstract    Thylakoids isolated from SA N 9785 (4-chloro-5-dimethylamino-2-phenyl-3(2H)-pyridazi-none)-treated pea plants showed an inhibition of "state transition" and the light-harvesting complex II (LHC II) phosphorylation-mediated changes in the energy distribution between photosystem II (PS II) and photosystem I (PS I) as measured by a decrease in PS II and an increase in PS I fluorescence yield. Interestingly, in these thylakoids the extent o f phosphory-lation-induced migration o f light-harvesting complex (LHC II-P) to non-appressed m em ­ brane regions was only marginally inhibited. We propose that the suppression in the ability for "state transition" by S A N D O Z 9785 (SA N 9785) treatment occurs due to a lack o f effec­ tive coupling of the migrated LHC II-P and PS I. Since we observed a decrease in the antenna size of PS I of the treated plants, the lack of effective coupling is attributed to this decrease in the antenna size of PS I.
