Fig. 11.9 Biosynthetic route 16D, which is responsible for the formation of MV Chlide a
ester from MV Pchlide a E in darkness. Routes 16D, is highlighted in blue (Adapted from
Rebeiz et al. 2003 )
(Belanger and Rebeiz 1980a , b ). It was assumed that the small amounts of DV Chl
a were a consequence of the photoconversion of small amounts of DV Pchlide
a ester. It has since come to our attention, that at room temperature, in-vivo,
conversion of newly formed DV Chlide a to DV Chl a is extremely rapid (Adra
1998 ). As a consequence the possible photoconversion of DV Pchlide a ester to DV
Chl a should be re-confirmed with isolated plastids at subzero temperatures
(Fig. 11.10 ).
