For land plants, the main chlorophyll pigments are chlorophyll a and b. Chlorophyll a, however, is the type of chlorophyll that can convert light energy and thus participates directly in the light reaction of photosynthesis. Chlorophyll b, in contrast, can absorb light energy but eventually relays...
lighted buds prolamellar bodies are not present; starch grains, lacking in plastids of darkened buds, are present instead.These results, showing for the first time greening and building of a photosynthetic apparatus in leaflets of buds of Gymnospermae grown in darkness, are interpreted ...
Indeed, their oxidation to colored compounds occurs readily [49] and explains the original naming for the NCCs as ‘rusty pigments’ [50]. Some of these oxidation products are also found in fresh extracts of senescent leaves, e.g. of C. japonicum, in which a yellow Chl catabolite (YCC) ...
The thylakoid system in plants is organized into two distinct domains: grana arranged in stacks of appressed membranes and non-appressed membranes consisting of stroma thylakoids and margins of granal stacks [1]. It is known that appressed membranes that form grana are not essential for photosyn...
Leaf Chl levels decline in plants transferred from low to high light, suggesting that adaptation to high light may include reducing light absorption by lowering the abundance of light-harvesting pigments (Murchie and Horton, 1997; Niyogi, 1999; Shin et al., 2017). However, it is unclear ...
In leaves, light is absorbed by chlorophyll and carotenoid pigments bound to proteins. The proteins control the orientation of the pig- ments relative to each other on a nanoscale, assuring efficient en- ergy transfer between these pigments. The protein environment may also modify the absorption ...
Carotenoid biosynthesis is essential for the generation of photosynthetic pigments, phytohormone production, and flower color development. The light harvesting like 3 (LIL3) protein, which belongs to the light-harvesting complex protein family in photosy
(i.e.,basal fluorescence).F0represents the energy dissipation via light-harvesting antenna pigments when excitation energy is not being transferred to the PSII reaction centres. After reachingF0, the application of a brief saturating pulse induces a maximum value of ChlF,Fm(PSII reaction centres ...
