Estimating absolute DNA abundance from replicated metabarcoding
Methods in Ecology and Evolution, EarlyView.Abstract Datasets derived from mixed‐template DNA amplification and sequencing (‘metabarcoding’) are common in environmental DNA (eDNA), microbiome or microbial ecology analyses. Such metabarcoding data have been broadly used to inform estimates of biodiversity, distribution and abundance across a wide range of species and habitats.

Frontiers in Plant Science, 2020 Organisms that have lost their photosynthetic capabilities are present in a variety of eukaryotic lineages, such as plants and disparate algal groups. Most of such non-photosynthetic eukaryotes still carry plastids, as these organelles retain essential ...

The FEBS Journal, EarlyView.Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Algal genes in aplastidic eukaryotes are not necessarily derived from historical plastids
, 2012 In photosynthetic eukaryotes, many genes were transferred from plastids or algal endosymbionts to nuclear genomes of host cells. These transferred genes are often considered genetic footprints of plastids.

Expression of the chloroplast genome: modern concepts and experimental approaches
Вавиловский журнал генетики и селекции, 2015 A unique feature of plants is the presence of two extranuclear genomes, chloroplasts and mitochondria. The chloroplast genome is relatively small, 100–120 genes, which encode less than 5 % of all proteins required for plastids to function.

The FEBS Journal, EarlyView.θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Frontiers in Plant Science, 2015 Plastids in the leaf epidermal cells of plants are regarded as immature chloroplasts that, like mesophyll chloroplasts, undergo binary fission. While mesophyll chloroplasts have generally been used to study plastid division, recent studies have suggested

BMC Biology, 2020 Background Plastid electron transport systems are essential not only for photosynthesis but also for dissipating excess reducing power and sinking excess electrons generated by various redox reactions.

Diversity and Plasticity of Plastids in Land Plants
, 2018 Plastids represent a largely diverse group of organelles in plant and algal cells that have several common features but also a broad spectrum of differences in respect of how they look (color, size, and ultrastructure), and what their specific function ...
