Solute channels of the outer membrane: from bacteria to chloroplasts [PDF]
, 2007 Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding

Journal of Integrative Plant Biology, EarlyView.In alfalfa, the transcription factor MsMYB71 activates the peroxiredoxin Q gene MsPrxQ, which helps remove harmful reactive oxygen species and improves drought tolerance. The WD40‐repeat protein MsPRL1 and the Cullin‐family scaffold protein MsCUL4 interact with and limit MsMYB71 accumulation and activity in an activation‐attenuation mechanism ...

A potential cyanobacterial ancestor of Viridiplantae chloroplasts [PDF]
, 2011 The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups.

Visualising Physcomitrium patens protoplasts with full‐rotation soft X‐ray tomography
Journal of Microscopy, EarlyView.Abstract Soft X‐ray tomography (SXT) is a label‐free, high‐resolution imaging modality that is optimal for 3D visualisation of whole hydrated cells. Although SXT has been extensively used to study remodelling in more than 130 mammalian cell lines, its application to plants remains largely unexplored. In this study, we present the first approach at full‐

Plastid-Nucleus Distance Alters the Behavior of Stromules
Frontiers in Plant Science, 2017 Plastids send “retrograde” signals to the nucleus to deliver information regarding their physiological status. One open question concerning this signal transfer is how the signal bridges the cytoplasm.

Proteomic Analysis of Chloroplast-to-Chromoplast Transition in Tomato Reveals Metabolic Shifts Coupled with Disrupted Thylakoid Biogenesis Machinery and Elevated Energy-Production Components [PDF]
, 2012 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

Journal of Phycology, EarlyView.Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

The Main Functions of Plastids
International audiencePlastids are semi-autonomous organelles like mitochondria and derive from a cyanobacterial ancestor that was engulfed by a host cell. During evolution, they have recruited proteins originating from the nuclear genome, and only parts

Evolution: Red Algal Genome Affirms a Common Origin of All Plastids
, 2004 Photosynthetic organelles (plastids) come in many forms and were originally thought to have multiple origins. The complete genome of the thermophilic red alga Cyanidioschizon merolae provides further evidence that all plastids derive from a single ...
