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 ...

Analysis of cis-acting expression determinants of the tobacco psbA 5’UTR in vivo [PDF]

, 2002
Chloroplast gene expression is predominantly regulated at the posttranscriptional levels of mRNA stability and translation efficiency. The expression of psbA, an important photosynthesis-related chloroplast gene, has been revealed to be regulated via its

CHLOROPLAST DEVELOPMENT IN OCHROMONAS DANICA [PDF]

The Journal of Cell Biology, 1962
When dark-grown cells of Ochromonas danica are placed in the light, the amount of chlorophyll a per cell increases 82-fold; the content of carotenoid pigment, 24-fold. Concomitantly with this increase in chlorophyll and carotenoid pigment, the small proplastid of dark-grown cells develops into a large lamellate chloroplast. During the first 12 hours in

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic

Cytological, Physiological, and Transcriptomic Analyses of the Leaf Color Mutant Yellow Leaf 20 (yl20) in Eggplant (Solanum melongena L.)

Plants
Leaf color mutants are ideal materials for studying chlorophyll metabolism, chloroplast development, and photosynthesis in plants. We discovered a novel eggplant (Solanum melongena L.) mutant yl20 (yellow leaf 20) that exhibits yellow leaves.

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

The Eucalyptus grandis chloroplast proteome: Seasonal variations in leaf development

, 2022
Chloroplast metabolism is very sensitive to environmental fluctuations and is intimately related to plant leaf development. Characterization of the chloroplast proteome dynamics can contribute to a better understanding on plant adaptation to different ...

Translational regulation in chloroplasts for development and homeostasis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015
Chloroplast genomes encode 100-200 proteins which function in photosynthesis, the organellar genetic system, and other pathways and processes. These proteins are synthesized by a complete translation system within the chloroplast, with bacterial-type ribosomes and translation factors.

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

Cytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.
