Frontiers in Plant Science, 2020 In Arabidopsis thaliana, the heterodimeric isopropylmalate isomerase (IPMI) is composed of a single large (IPMI LSU1) and one of three different small subunits (IPMI SSU1 to 3). The function of IPMI is defined by the small subunits. IPMI SSU1 is required

Large-Scale Phylogenomic Analyses Indicate a Deep Origin of Primary Plastids within Cyanobacteria
, 2011 International audienceThe emergence of photosynthetic eukaryotes has played a crucial role in evolution and has strongly modified earth's ecology. Several phylogenetic analyses have established that primary plastids arose from a cyanobacterium through ...

Advanced Science, EarlyView.ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Ultraviolet screening by slug tissue and tight packing of plastids protect photosynthetic sea slugs from photoinhibition [PDF]
, 2022 One of the main mysteries regarding photosynthetic sea slugs is how the slug plastids handle photoinhibition, the constant light-induced damage to Photosystem II of photosynthesis.

A Modular PLUG‐IN Photosynthetic Chassis With Tunable Thermal Control for Mammalian Systems
Advanced Science, EarlyView.This work establishes a “plug‐in” chassis compatible with mammalian systems that synchronizes growth, production, and cell‐wall re‐configuration, providing a versatile platform for photosynthetic bioproduction and microalgal synthetic biology. ABSTRACT Microalgae are promising photosynthetic platforms for high‐value compounds, yet their industrial use ...

Ultrastructural changes during megasporogenesis in Epipactis (Orchidaceae)
Acta Societatis Botanicorum Poloniae, 2014 Plastids were temporarily localized within the micropylar portion of the early first prophase Epipactis meiocyte. Some of these plastids were observed in close proximity to the nuclear envelope.

Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae
Applications in Plant Sciences, EarlyView.Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...

, 2010 Organelles, called plastids, are the main sites of photosynthesis in eukaryotic cells. Chloroplasts, as well as any other pigment containing cytoplasmic organelles that enables the harvesting and conversion of light and carbon dioxide into food and ...

Photoprotection and genetic autonomy of plastids in photosynthetic sea slugs [PDF]
, 2022 Certain sea slugs “steal” the photosynthetic cellular organelles, the plastids, from their prey algae and incorporate them, still functional, inside their own cells. These animals can then remain photosynthetic for months.

Applications in Plant Sciences, EarlyView.Abstract Premise DNA barcoding for timber species identification requires comprehensive reference datasets, informative DNA barcodes, and cost‐effective protocols. We developed a workflow leveraging Hyb‐Seq (target capture sequencing and genome skimming) to address these challenges, and we tested it on four genera from the mahogany family (Meliaceae ...
