“…By contrast, the thylakoids in cyanobacteria consist mainly of single layers formed by long lamellae, and extensive stacking of the grana lamellae is not observed [3]. Thus, thylakoid membrane systems evolved in cyanobacteria but became more complex in algae and plants [2], and the ultrastructure and composition differences of the thylakoids in cyanobacteria, algae and plants correspond well with their evolutionary positions [3].…”

“…The most advanced and efficient thylakoids are present in the chloroplasts of land plants, in which they are arranged into extensive, highly interconnected networks of grana stacks connected by stroma lamellae [2]. By contrast, the thylakoids in cyanobacteria consist mainly of single layers formed by long lamellae, and extensive stacking of the grana lamellae is not observed [3].…”

Major multi-protein photosynthetic complexes, located in thylakoid membranes, are responsible for the capture of light and its conversion into chemical energy in oxygenic photosynthetic organisms. Although the structures and functions of these photosynthetic complexes have been explored, the molecular mechanisms underlying their assembly remain elusive. In this review, we summarize current knowledge of the regulatory components involved in the assembly of thylakoid membrane protein complexes in photosynthetic organisms. Many of the known regulatory factors are conserved between prokaryotes and eukaryotes, whereas others appear to be newly evolved or to have expanded predominantly in eukaryotes. Their specific features and fundamental differences in cyanobacteria, green algae and land plants are discussed.

“…In this case, the transfer system for the newly synthesized lipids and proteins into the forming thylakoids can be similar to that occurring during the direct development of a proplastid into a chloroplast (Rast et al, 2015). However, it is still not clear whether the degrading PLB transforms into thylakoids continuously or through the formation of vesicles (Rosinski and Rosen, 1972;Adam et al, 2011;Grzyb et al, 2013;Pribil et al, 2014).…”

“…It involves changes in gene expression together with the transcriptional and translational control of both nuclear and plastid genes. These genes can be regulated by anterograde and retrograde signals, the synthesis of necessary lipids and pigments, the import and routing of the nucleusencoded proteins into plastids, protein-lipid interactions, the insertion of proteins into the plastid membranes, and the assembly into functional complexes (Vothknecht and Westhoff, 2001;Baena-González and Aro, 2002;Kota et al, 2002;Stern et al, 2004;López-Juez, 2007;Waters and Langdale, 2009;Solymosi and Schoefs, 2010;Adam et al, 2011;Pogson and Albrecht, 2011;Ling et al, 2012;Jarvis and López-Juez, 2013;Lyska et al, 2013;Belcher et al, 2015;Börner et al, 2015;Dall'Osto et al, 2015;Ling and Jarvis, 2015;Rast et al, 2015;Sun and Zerges, 2015;Yang et al, 2015). Chloroplast biogenesis is highly integrated with cell and plant development, especially with photomorphogenesis (Pogson et al, 2015), and is controlled by cellular and organismal regulatory mechanisms such as the ubiquitin-proteasome system (Jarvis and López-Juez, 2013).…”

“…The longer wavelength forms are bound to PLBs, while this shorter wavelength form, unbound to LPOR, is mainly found in PTs. In addition to LPOR, PLBs contain enzymes of the chlorophyll and carotenoid biosynthesis pathways, enzymes of the Calvin cycle, and proteins involved in photosynthetic light reactions (subunits of ATP synthase, the oxygen-evolving complex, cytochrome b 6 f, plastocyanin, and ferrodoxin-NADPH oxidoreductase) and other proteins necessary during photomorphogenesis with the exception of the core subunits and the antenna complexes of the two photosystems (von Zychlinski et al, 2005;Kleffmann et al, 2007;Blomqvist et al, 2008;Adam et al, 2011).…”

Three-Dimensional Visualization of the Tubular-Lamellar Transformation of the Internal Plastid Membrane Network during Runner Bean Chloroplast Biogenesis

et al. 2016

Chloroplast biogenesis is a complex process that is integrated with plant development, leading to fully differentiated and functionally mature plastids. In this work, we used electron tomography and confocal microscopy to reconstruct the process of structural membrane transformation during the etioplast-to-chloroplast transition in runner bean (Phaseolus coccineus). During chloroplast development, the regular tubular network of paracrystalline prolamellar bodies (PLBs) and the flattened porous membranes of prothylakoids develop into the chloroplast thylakoids. Three-dimensional reconstruction is required to provide us with a more complete understanding of this transformation. We provide spatial models of the bean chloroplast biogenesis that allow such reconstruction of the internal membranes of the developing chloroplast and visualize the transformation from the tubular arrangement to the linear system of parallel lamellae. We prove that the tubular structure of the PLB transforms directly to flat slats, without dispersion to vesicles. We demonstrate that the grana/stroma thylakoid connections have a helical character starting from the early stages of appressed membrane formation. Moreover, we point out the importance of particular chlorophyll-protein complex components in the membrane stacking during the biogenesis. The main stages of chloroplast internal membrane biogenesis are presented in a movie that shows the time development of the chloroplast biogenesis as a dynamic model of this process.

Nature‐Inspired Design and Application of Lipidic Lyotropic Liquid Crystals

Amphiphilic lipids aggregate in aqueous solution into a variety of structural arrangements. Among the plethora of ordered structures that have been reported, many have also been observed in nature. In addition, due to their unique morphologies, the hydrophilic and hydrophobic domains, very high internal interfacial surface area, and the multitude of possible order−order transitions depending on environmental changes, very promising applications have been developed for these systems in recent years. These include crystallization in inverse bicontinuous cubic phases for membrane protein structure determination, generation of advanced materials, sustained release of bioactive molecules, and control of chemical reactions. The outstanding diverse functionalities of lyotropic liquid crystalline phases found in nature and industry are closely related to the topology, including how their nanoscopic domains are organized. This leads to notable examples of correlation between structure and macroscopic properties, which is itself central to the performance of materials in general. The physical origin of the formation of the known classes of lipidic lyotropic liquid crystalline phases, their structure, and their occurrence in nature are described, and their application in materials science and engineering, biology, medical, and pharmaceutical products, and food science and technology are exemplified.
