Webthylakoids [4, 5]. A proportional decline in the PS I and II complexes in the chlorotica 2014 pea mutant is attended with partial reduction of the overall chloro-plast membrane system while both granal and inter-granal regions were retained, whereas loss of PS I RC in chlorotica 2004 causes reduction of mostly inter-granal regions [6]. WebMost of PSII resides in the approached regions of stacked thylakoids (partitions), while PSI and the ATP synthase only occur in the stromal thylakoids and in all the unstacked regions of granal thylakoids (end granal membranes and margins). Finally, the Cyt b 6 f is rather homogeneously distributed in the thylakoid system.
