dc.description.abstract | Plant productivity is determined by the conversion of solar energy into biomass through
oxygenic photosynthesis, a process performed by protein-cofactor complexes including
photosystems (PS) II and I, and ATP synthase. These complexes are embedded in
chloroplast thylakoid membrane lipids, which thus function as structural support of the
photosynthetic machinery and provide the lipid matrix to avoid free ion diffusion. The lipid
and fatty acid composition of thylakoid membranes are unique in chloroplasts and
cyanobacteria, which implies that these molecules are specifically required in oxygenic
photosynthesis. Indeed, there is extensive evidence supporting a relevant function of
glycerolipids in chloroplast biogenesis and photosynthetic efficiency in response to
environmental stimuli, such as light and temperature. The rapid acclimation of higher
plants to environmental changes is largely based on thiol-based redox regulation and the
disulphide reductase activity thioredoxins (Trxs), which are reduced by ferredoxin (Fdx)
via an Fdx-dependent Trx reductase. In addition, chloroplasts harbour an NADPHdependent Trx reductase C, which allows the use of NADPH to maintain the redox
homeostasis of the organelle. Here, we summarise the current knowledge of chloroplast
lipid metabolism and the function of these molecules as structural basis of the complex
membrane network of the organelle. Furthermore, we discuss evidence supporting the
relevant role of lipids in chloroplast biogenesis and photosynthetic performance in response
to environmental cues in which the redox state of the organelle plays a relevant role. | es |
