Fig. 13.18 Biosynthesis of MV Chl b via route 6 in the Nec 2 corn mutant and in picoplanktons
(Adapted from Fig. 6.3 of Chap. 6 )
picoplankton (see above) which form and accumulate only DV Chl a and DV Chl b .
Precursor- product relationships between DVChl a and DVChl b in vivo and in vitro
is required however, to validate this hypothesis.
Conversion of DV Chlide b to DV Chl b via Route 6
Conversion of DVChlide b to DV Chl b via route 6 (Fig. 13.18 ) may also take place in
the Nec 2 corn mutant and in the prochlorophyte picoplankton (Chisholm et al. 1988 ,
1992 ; Goerike and Repeta 1992 ) which form and accumulate only DV Chl a and DV
Chl b . Precursor- product relationships between DV Chlide b and DV Chl b in these
organisms in vivo and in vitro is required however, to validate this hypothesis.
