NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches [PDF]
Phytochrome signaling in the nucleus can activate expression of photosynthesis-associated genes in plastids. Here Yang et al. show that NCP is a dual-targeted protein that promotes phytochrome B localization to photobodies in the nucleus while ...

Impact of edaphoclimatic conditions and crop season on olive oil's fatty acids
Abstract The olive tree (Olea europaea L.) fruit oil attracts widespread interest because of its high content of monounsaturated fatty acids. However, a neglected area in the field is the edaphoclimatic factors impact, which is poorly understood. Bearing this in mind, the purpose of this investigation was to evaluate the impact of the edaphoclimatic ...

Endosymbiotic ratchet accelerates divergence after organelle origin
Primary endosymbiosis gave rise to mitochondria and plastids. The proximate impacts of organelle origin on lineage evolution have not been addressed at the population level. Using data from the photosynthetic amoeba Paulinella, we hypothesize that primary endosymbiosis accelerates lineage divergence, a process we refer to as the endosymbiotic ratchet ...

Abstract The Apocynaceae subfamilies Secamonoideae and Asclepiadoideae have undergone several transitions during their evolution with regard to growth form and degree of woodiness. In this study, we present a wood anatomical overview of both subfamilies that complements previous work on the remaining Apocynaceae.

Abstract The Carthamus‐Carduncellus complex is formed by approximately 50 taxa that are widely distributed throughout the Mediterranean basin and western Asia. The generic delineation of this complex has always been controversial. Currently, there are three widely diverging taxonomical proposals, suggesting that the complex is formed by (1) a single ...

Chloroplast to chromoplast transition in tomato fruit: spectral confocalmicroscopy analyses of carotenoids and chlorophylls in isolated plastids and time-lapse recording on intact live tissue [PDF]
During evolution, chromoplasts have emerged as plastid structures which accumulate pigments to facilitate flower pollination and seed dispersal of fleshy fruit.

Abstract Despite recent advances in high‐throughput DNA sequencing technologies, a lack of locally relevant DNA reference databases limits the potential for DNA‐based monitoring of biodiversity for conservation and biosecurity applications. Museums and national collections represent a compelling source of authoritatively identified genetic material for

tRNA functional signatures classify plastids as late-branching cyanobacteria. [PDF]
BackgroundEukaryotes acquired the trait of oxygenic photosynthesis through endosymbiosis of the cyanobacterial progenitor of plastid organelles. Despite recent advances in the phylogenomics of Cyanobacteria, the phylogenetic root of plastids remains ...

The Arabidopsis arc5 and arc6 mutations differentially affect plastid morphology in pavement and guard cells in the leaf epidermis. [PDF]
Chloroplasts, or photosynthetic plastids, multiply by binary fission, forming a homogeneous population in plant cells. In Arabidopsis thaliana, the division apparatus (or division ring) of mesophyll chloroplasts includes an inner envelope transmembrane ...

Proteomic Analysis of Chloroplast-to-Chromoplast Transition in Tomato Reveals Metabolic Shifts Coupled with Disrupted Thylakoid Biogenesis Machinery and Elevated Energy-Production Components [PDF]
A comparative proteomic approach was performed to identify differentially expressed proteins in plastids at three stages of tomato(Solanum lycopersicum) fruit ripening (mature-green, breaker, red). Stringent curation and processing of the data from three
