Fig. 13.14 Biosynthesis of MV Chl b via route 11 in greening DMV-LDV-LDMV plants during
the light phases of the photoperiod (Adapted from Fig. 6.4 of Chap. 6 )
other biosynthetic routes that operate during the light phases of the photoperiod, our
guess would be that the putative MV Chl b formed via route 11 is destined to LHCII
and other antenna Chl-protein complexes (Fig. 13.14 ).
Biosynthesis of MV Chl b from MV Pchlide b via Route 0 0 in Greening
DMV-LDV-LDMV Plants During the Light Phases of the Photoperiod
The Operation of biosynthetic route 0 0 in DMV-LDV-LDMV plants during
photoperiodic greening is justified by the detection and solubilization of 4-Vinyl
Mpe reductase (4VMpeR) in greening barley etiochloroplasts (Kolossov and
Rebeiz 2010 ). Such etiochloroplasts can actively convert MV Mpe to MV Pchlide
a (Tripathy and Rebeiz 1986 ) (Fig. 13.15 ).
