Chlorophyll Sees Red Among the first facts students learn about natural world is that plants owe their green color to pigment chlorophyll. There have actually been a handful of slightly different chlorophyll variants uncovered over years, and Chen et al. (p. 1318 , published online 19 August) found another in bacteria from Shark Bay, Australia. The variant displayed red-shifted absorption spectrum, which extended into near-infrared region due insertion formyl group on molecule's periphery....
Acaryochloris marina is a unique cyanobacterium that able to produce chlorophyll d as its primary photosynthetic pigment and thus efficiently use far-red light for photosynthesis. species have been isolated from marine environments in association with other oxygenic phototrophs, which may driven the niche-filling introduction of d. To investigate these adaptations, we sequenced complete genome A. marina. The DNA content composed 8.3 million base pairs, among largest bacterial genomes far....
A Chl f ‐containing filamentous cyanobacterium was purified from stromatolites and named as Halomicronema hongdechloris gen., sp. nov. after its phylogenetic classification the morphological characteristics. Hongdechloris contains four main carotenoids two chlorophylls, a . The ratio of to is reversibly changed 1:8 under red light an undetectable level white‐light culture conditions. Phycobiliproteins were induced white growth fluorescence emission peak 748 nm identified due results suggest...
Abstract Chlorophylls (Chl) play pivotal roles in energy capture, transfer and charge separation photosynthesis. Among Chls functioning oxygenic photosynthesis, Chl f is the most red-shifted type first found a cyanobacterium Halomicronema hongdechloris . The location function of photosystems are not clear. Here we analyzed high-resolution structures photosystem I (PSI) core from H. grown under white or far-red light by cryo-electron microscopy. structure showed that, PSI binds 83 7 ,...
Melatonin involves in improving tolerance to abiotic and biotic stresses by regulating various biological processes. However, little is known about the underlying mechanism. Here, we investigated effects of exogenous melatonin on seed germination halophyte Limonium bicolor under salt stress. Specifically, examined effect stress germination, concentration, changes concentrations nutrients, amylase activity, hormones L. seeds with without pre-treatment melatonin. Seed was significantly...
Photosynthetic manipulation provides new opportunities for enhancing crop yield. However, understanding and quantifying the importance of individual multiple manipulations on seasonal biomass growth yield performance target crops across variable production environments is limited. Using a state-of-the-art cross-scale model in APSIM platform we predicted impact altering photosynthesis enzyme-limited (Ac ) electron transport-limited (Aj rates, dynamics canopy photosynthesis, growth, formation...
Despite the fact that heliobacteria are only phototrophic representatives of bacterial phylum Firmicutes, genomic analyses these organisms have yet to be reported. Here we describe complete sequence and analysis genome Heliobacterium modesticaldum, a thermophilic species belonging this unique group phototrophs. The is single 3.1-Mb circular chromosome containing 3,138 open reading frames. As suspected from physiological studies failed show photoautotrophic growth, genes encoding enzymes for...
Photosynthetic organisms provide, directly or indirectly, the energy that sustains life on earth by harvesting light from sun. The amount of impinging surface vastly surpasses needs including man. Harvesting sun is, therefore, an option for a sustainable source: improving biomass production, indirectly coupling it to production hydrogen fuel or, conceptually, using photosynthetic strategies technological solutions based non-biological hybrid materials. In this review, we summarize various...
A chlorophyll f containing cyanobacterium, Halomicronema hongdechloris (H. hongdechloris) was isolated from a stromatolite cyanobacterial community. The extremely slow growth rate of H. has hindered research on this newly cyanobacterium and the investigation f-photosynthesis. Therefore, optimizing culture conditions become an essential requirement for future research. This work investigated effects various conditions, nutrients light environments to determine optimal biosynthetic f. Based...
Chlorophyll d and chlorophyll f are red-shifted chlorophylls, because their Qy absorption bands significantly compared with a. The chlorophylls broaden the light region further into far red light. presence of in photosynthetic systems has opened up new possibilities research on photosystem energetics challenged unique status a oxygenic photosynthesis. In this review, we report chemistry function photosynthesis summarise adaptations that have allowed proliferation d- f-containing organisms...
Summary Reticulate speciation caused by interspecific hybridization is now recognized as an important mechanism in the creation of biological diversity. However, depicting patterns phylogenetic networks for lineages that have undergone gene flow challenging. Here we sequenced 25 taxa representing natural diversity genus Actinidia with average mapping depth 26× on reference genome to reconstruct their reticulate history. We found evidence, including significant tree discordance, cytonuclear...
Acaryochloris marina is a unique cyanobacterium using chlorophyll d (Chl ) as its major pigment and thus can use far-red light for photosynthesis. Photosystem II (PSII) of A. associates with number prochlorophyte Chl-binding (Pcb) proteins to act the light-harvesting system. We report here cryo-electron microscopic structure PSII-Pcb megacomplex from at 3.6-angstrom overall resolution 3.3-angstrom local resolution. The organized tetramer consisting two PSII core dimers flanked by sixteen...
