Loss of Plastid Developmental Genes Coincides With a Reversion to Monoplastidy in Hornworts
Frontiers in Plant Science, 2022 The first plastid evolved from an endosymbiotic cyanobacterium in the common ancestor of the Archaeplastida. The transformative steps from cyanobacterium to organelle included the transfer of control over developmental processes, a necessity for the host

Molecular Evolution of Aphthoviruses
Virus Genes, 1995 Aphthoviruses are an important group of animal pathogens. A combination of genetic and structural studies has revealed one of the main principles governing their evolution: severe limitations to variation imposed by functional and structural constraints, in conjunction with high mutation and recombination rates operating during genome replication ...

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides
Frontiers in Microbiology, 2014 DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept

Elusive data underlying debate at the prokaryote-eukaryote divide
Biology Direct, 2018 Background The origin of eukaryotic cells was an important transition in evolution. The factors underlying the origin and evolutionary success of the eukaryote lineage are still discussed.

THE MOLECULAR EVOLUTION OF ACTIN [PDF]
Genetics, 1986 ABSTRACT We have investigated the molecular evolution of plant and nonplant actin genes comparing nucleotide and amino acid sequences of 20 actin genes. Nucleotide changes resulting in amino acid substitutions (replacement substitutions) ranged from 3-7% for all pairwise comparisons of animal actin genes with the following exceptions ...

Plastid origin: who, when and why?
Acta Societatis Botanicorum Poloniae, 2014 The origin of plastids is best explained by endosymbiotic theory, which dates back to the early 1900s. Three lines of evidence based on protein import machineries and molecular phylogenies of eukaryote (host) and cyanobacterial (endosymbiont) genes point

The legume-specific transcription factor E1 controls leaf morphology in soybean
BMC Plant Biology, 2021 Background The leaf is a determinate organ essential for photosynthesis, whose size and shape determine plant architecture and strongly affect agronomic traits. In soybean, the molecular mechanism of leaf development is not well understood. The flowering

The complete mitochondrial genome of Syrphus ribesii (Diptera: Syrphoidea: Syrphidae)
Mitochondrial DNA. Part B. Resources, 2021 The complete mitochondrial genome of Syrphus ribesii was determined in this study. The double-stranded circular DNA molecule was 16,530 bp in length, containing 37 typical genes: 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and an A + T ...

A sea slug’s guide to plastid symbiosis
Acta Societatis Botanicorum Poloniae, 2014 Some 140 years ago sea slugs that contained chlorophyll-pigmented granules similar to those of plants were described. While we now understand that these “green granules” are plastids the slugs sequester from siphonaceous algae upon which they feed ...
