The legume-specific transcription factor E1 controls leaf morphology in soybean

open access: yesBMC 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 effect of molecular, morphological and spectral reflectance evolution on nicotiana polyploids of different ages [PDF]

open access: yes, 2010
PhDInterspecific hybridisation accompanied by multiplication of chromosome number, or allopolyploidy, results in rapid genetic, epigenetic, chromosomal and morphological changes.

A sea slug’s guide to plastid symbiosis

open access: yesActa 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 ...

Host-dependent impairment of parasite development and reproduction in the acanthocephalan model

open access: yesCell & Bioscience, 2022
Background A central question in parasitology is why parasites mature and reproduce in some host species but not in others. Yet, a better understanding of the inability of parasites to complete their life cycles in less suitable hosts may hold clues for ...

Autonomous assembly of synthetic oligonucleotides built from an expanded DNA alphabet. Total synthesis of a gene encoding kanamycin resistance

open access: yesBeilstein Journal of Organic Chemistry, 2014
Background: Many synthetic biologists seek to increase the degree of autonomy in the assembly of long DNA (L-DNA) constructs from short synthetic DNA fragments, which are today quite inexpensive because of automated solid-phase synthesis.

Revision of Gyrodactylus salaris phylogeny inspired by new evidence for Eemian crossing between lineages living on grayling in Baltic and White sea basins [PDF]

open access: yesPeerJ, 2018
In this research, grayling-specific Gyrodactylus salaris Malmberg, 1957 isolates from Baltic Sea basin were collected in Sweden for the first time. Samples were obtained in three drainage systems: Kalixälven (River Kaitum), Ljungan (River Sölvbacka ...

Big and Slow: Phylogenetic estimates of molecular evolution in baleen whales (Suborder Mysticeti).

open access: yes, 2009
Published in a leading journal of molecular evolutionary, this article presents the largest databases available to date of mitochondrial and nuclear intron sequences to estimate the ‘neutral’ rate of molecular evolution in the largest species of animals ...

Maximum-likelihood divergence date estimates based on rRNA gene sequences suggest two scenarios of Trypanosoma cruzi intraspecific evolution

open access: yes, 2001
The phylogenetic relationships of Trypanosoma cruzi strains were inferred using maximum-likelihood from complete 18S rDNA sequences and D7-24S alpha rDNA regions from 20 representative strains of T. cruzi. For this we sequenced the 18S rDNA of 14 strains

Characterization of the BspA and Pmp protein family of trichomonads

open access: yesParasites & Vectors, 2019
Background Trichomonas vaginalis is a human-infecting trichomonad and as such the best studied and the only for which the full genome sequence is available considering its parasitic lifestyle, T.
