Researchers used long-read sequencing to analyze the nuclear genome of Amorphochlora amoebiformis, revealing an extremely high proportion of introns (74%) compared to other eukaryotic genomes. The study provides important insights into the evolutionary dynamics and potential functional roles of introns in eukaryotic genomes.
Scientists have created a micro-algal platform that allows for automated and fast testing of chloroplast genetic modifications, opening up plant chloroplasts to high-throughput applications. This platform enables researchers to fine-tune genetic circuits and identify which modifications have real potential.
Researchers from Osaka University discovered a new type of protein in red algae Cyanidioschyzon merolae associated with chloroplast protein import and targeting mechanism. The study found that red algae use distinct mechanisms involving GTP-binding proteins to transport proteins across the inner membrane of chloroplasts.
Researchers found that GPT1 targets both plastids and the endoplasmic reticulum, enabling simultaneous formation of reduction power. The oxidative pentose-phosphate pathway also occurs in peroxisomes, producing NADPH and ribulose-5-phosphate.
The discovery of two novel dinoflagellates, MGD and TGD, reveals that the process of organellogenesis is less advanced in these strains than previously thought. The organisms contain nucleomorphs with DNA transfer events ongoing, allowing researchers to study this critical stage of organelle formation.
A team of researchers at the Alfred Wegener Institute identified a parasite with functional mitochondria that produce energy without its own genetic material. The Amoebophrya ceratii parasite has nearly all metabolic processes working, allowing it to thrive on its own with significantly reduced genetic material.
Researchers sequenced and analyzed the plastid genomes of two species of Balanophora, a fully parasitic mushroom-like plant, revealing a nontraditional genetic code. The discovery includes a novel stop codon TAG that encodes tryptophan, and most genes involved in protein synthesis reside outside the traditional plastid genome.
A Northeast sea slug has been found to store millions of algal plastids in its gut lining after pilfering them from the brown alga Vaucheria litorea, a food source rich in tiny solar panels. The sea slug survives solely on photosynthesis for up to six months by protecting and utilizing the stolen plastids.
Scientists discovered a single-celled plankton's 'eye' contains layers of mitochondria and plastids that resemble the lens, cornea, iris, and retina of multicellular eyes. The researchers found clues suggesting the structure may aid in detecting prey and communicating with other parts of the cell.
A new study by UBC researchers has definitively linked the evolutionary histories of malaria and dinoflagellate algae through the genome of Chromera, a symbiotic coral organism. The discovery resolves a long-standing scientific debate and could provide crucial information for tackling diseases.
A recent study by Dr. David Spooner highlights the limitations of DNA barcoding in distinguishing species within complex plant groups, such as wild potatoes (Solanum section Petota). The technique's accuracy is compromised due to intraspecific variation and hybridization among species.
Researchers have discovered that sea slugs can survive and thrive using a process similar to photosynthesis, harnessing solar power from tiny organelles called plastids. The slug's ability to retain these plastids allows it to convert sunlight into food, enabling it to make its own sustenance like plants.
Researchers at Rutgers University have discovered a new approach to contain genes in genetically modified (GM) crops by implanting them into plastids, minimizing the risk of escape. This innovation has the potential to alleviate concerns about 'foreign genes' contaminating wild species and ecosystems.
Researchers analyzed Paulinella's plastid genome, finding it closely related to cyanobacteria and retaining ancient genetic features. The study offers insights into the establishment of plastids and the transition from single-celled hosts to complex organisms.
