Kinetics and quantum yield of photoconversion of protochlorophyll(ide) to chlorophyll(ide) a

Protochlorophyll(IDE) holochrome subunits from a mutant defective in the regulation of protochlorophyll(IDE) synthesis

“…The progress of photoconversion of Pchl from the three genotypes is similar, if not identical ( fig. 2), and as found earlier for Pchl-H from the wild type [4], follows first order kinetics in all cases. The small departures of the points representing Pchl-H from tig-o34/tig-034 from the line ( fig.…”

“…A 12.5 cm layer of water was introduced into the light path. Energy measurements have been described elsewhere [4].…”

“…The fractions of active Pchl remaining after leaves, respcctlvely, weredetermined as described earlier [4]. The progress of photoconversion of Pchl from the three genotypes is similar, if not identical ( fig.…”

“…wt. of 63 000 and giving no evidence of more than one Pchl molecule per unit have been obtained from the primary leaves of etiolated barley (Hordeum vulgare L,) seedlings [3][4][5].…”

Light and life III

“…This photochemical reaction controls the conversion of the prolamellar bodies to thylakoids. The events following the excitation of protochlorophyll are very incompletely understood (15,27,16). Thus we must leave the two gentlemen to their argument and move on to the next character, retinal (Fig.…”
