Fig. 8.5 Biosynthetic routes 10, 11, and 13 which are responsible for the formation of DV Pchlide
a
from DV Mpe in LMV-DDV-LDMV plant species. These routes are highlighted in
green
It is unclear at this stage whether the spatial biosynthetic heterogeneity of DV
Pchlide
a
is accompanied by chemical biosynthetic heterogeneity or not. In other
words, it is unclear whether the proposed biosynthesis of DV Pchlide
a
fromDVMpe
via routes 10, 11, and 13 is catalyzed by identical Pchlide
a
cyclases or by different
Pchlide
a
isozymes. These biosynthetic routes will be discussed further later on.
Biosynthesis of DV Pchlide a via Biosynthetic Routes 10, and 11 in Etiolated
DMV-LDV-LDMV Plants in Darkness and in Green DMV-LDV-LDMV Plants
During the Dark Phases of the Photoperiod
DV Pchlide
a
is formed via routes 10 and 11 (Fig.
8.5
) in dark-grown DMV-LDV-
LDMV plant species and during the dark phases of the photoperiod.
