ester, he reported the occurrence of another esterified Pchl namely DV Pchlide ester
(Fig.
2.8
, I) in the inner pumpkin seed coat (Jones
1966
). In 1969, this finding was
confirmed by Houssier and Sauer (
1969
). Since then, it was assumed that only MV
Pchlide ester (Fig.
2.8
, II) normally occurred in green plants, except in some
particular cases such as the inner cucurbid seed coat.
Then in 1980, Belanger and Rebeiz reported that in many cases, in addition to
MV Pchlide ester, small quantities of DV Pchlide ester (Fig.
2.8
, I) occurred
routinely in green plants (Belanger and Rebeiz
1980a
). The function of these
2.10.1.4 Discovery of Divinyl Chlorophyll a Occurrence
in Green Plants
With the discovery of the occurrence of DV Pchlide and DV Chlide, it was
conjectured that it was a matter of time before the occurrence of DV Chl
a
(Fig.
2.7
, 4c) would be reported in green plants. Indeed, in 1980 Belanger and
Rebeiz reported that upon a 47 ms illumination of etiolated cucumber cotyledons
containing MV and DV Pchlide
a
as well as Pchlide ester
a
, the appearance of DV
Chlide
a
and DV Chl
a
was noted along with the MV analogs (Belanger and Rebeiz
1980b
; Wu and Rebeiz
1984
). Also in 1981 and 1982, Bazzaz reported the detection
of DV Chl
a
accumulation in a lethal corn mutant (Bazzaz
1981
; Bazzaz et al.
1982
).
Then in 1983 Gieskes and Kraay (
1983
) reported the occurrence of a Chl in the
phytoplankton of various oceans, that had slightly different spectroscopic properties
than conventional Chl
a
. That Chl had the spectroscopic properties of the DV Chl

that we described in 1980 (Belanger and Rebeiz
1980b
). In future publications, it
