Mitochondrial and apicoplast genome copy abundances of haemosporidian parasites are explained by host species and parasitic lineage

Frontiers in Ecology and Evolution
Endosymbiotic organelles, such as mitochondria and plastids, contain own remnant genomes (nucleoids), whose variable abundance in cells may be adaptive to the physiological necessities and functions of the cells.

Multifaceted Study of Medicago marina Essential Oil: Chemical Composition, Antidiabetic, and Phytotoxic Insights via In Vitro and In Silico Approaches

Chemistry &Biodiversity, EarlyView.
ABSTRACT The essential oil of Medicago marina was subjected to analysis at vegetative and reproductive stages of development, with a particular emphasis on its chemical composition, α‐amylase inhibition, and allelopathic activities. The results of the gas chromatography and molecular docking studies demonstrated alterations in oil yield and composition

5‐Thiohistidine N‐Acetyltransferase from Proteiniphilum Saccharofermentans

ChemBioChem, EarlyView.
Proteiniphilum saccharofermentans, a Gram‐negative facultative anaerobe, produces an N‐acetyl transferase (5THNAT) that acetylates 5‐thiohistidine using acetyl‐CoA. This reaction competes with OvoC‐mediated Nπ‐methylation of the same substrate.

The biosynthesis of galactolipids in red clover (Trifolium pratense) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry [PDF]

, 1972
Galactolipids occur in all cells capable of the photosynthetic evolution of oxygen. The main galactolipids are monogalactosyl diglyceride (MGDG), digalactosyldiglyceride (DGDG) and sulfolipid (SL), MGDG being the most abundant.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Best Practices for Optimization of Phytoplankton Analysis in Natural Waters Using CytoSense Flow Cytometers

Cytometry Part A, EarlyView.
ABSTRACT The use of flow cytometry to investigate phytoplankton functional groups is rapidly expanding worldwide, using lab‐ or ship‐based instruments or autonomous environmental monitoring platforms. Automation, coupled with greater autonomy, allows for higher spatial and temporal resolution of phytoplankton groups, enhancing understanding of their ...

Which global circulation model works best for my region? Concordance with genetic data for a Neotropical shrew

Ecography, EarlyView.
Copious questions in global change biology require estimates of climatic suitability for species in the past or future, often via transfers of ecological niche models (ENMs) using outputs from global circulation models (GCMs). However, available GCMs differ markedly, affecting hindcasts and forecasts of species potential distributions. We propose using

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

Ecography, EarlyView.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...
