Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Genetic variability and relationship among different accessions of Froriepia subpinata Bail (Gijavash) an endangered medicinal plant from Iran revealed by ISSR and IRAP markers

open access: yesAdvances in Horticultural Science, 2021
The genetic variability of Froriepia subpinata Ledeb. Bail., an endangered Iranian endemic species, has been estimated with a total of 52 accessions using 20 markers including ISSR and IRAP. The results showed the polymorphic band produced by primers was

Evolutionary dynamics of insertion sequences in relation to the evolutionary histories of the chromosome and symbiotic plasmid genes of Rhizobium etli populations [PDF]

open access: yes, 2010
Insertion sequences (IS) are mobile genetic elements that are distributed in many prokaryotes. In particular, in the genomes of the symbiotic nitrogen-fixing bacteria collectively known as rhizobia, IS are fairly abundant in plasmids or chromosomal ...

Comparing RADseq and microsatellites for estimating genetic diversity and relatedness — Implications for brown trout conservation

open access: yesEcology and Evolution, 2019
The conservation and management of endangered species requires information on their genetic diversity, relatedness and population structure. The main genetic markers applied for these questions are microsatellites and single nucleotide polymorphisms ...

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Enhancement of germination potential in lemon basil (Ocimum africanum Lour.) seeds using radiofrequency cold plasma treatment with oxygen, argon, and their combination

open access: yesBMC Plant Biology
Background A rapid, cost-effective, and eco-friendly method was investigated to enhance the germination potential of lemon basil (Ocimum africanum Lour.) seeds using radiofrequency (RF) cold plasma treatment, addressing poor germination due to seed ...

Conservation genetics of amphibians [PDF]

open access: yesHeredity, 2005
Amphibians are good models for investigating the genetics of wild animal populations because they are: (1) widely distributed in most ecosystems; (2) easy to sample in breeding assemblages; (3) often philopatric to breeding sites, generating high levels of population genetic structure; (4) amenable to controlled crossings in the laboratory; and (5) of ...

Genetic Diversity and Conservation Units: Dealing With the Species-Population Continuum in the Age of Genomics

open access: yesFrontiers in Ecology and Evolution, 2018
Current approaches to biodiversity conservation are largely based on geographic areas, ecosystems, ecological communities and species, with less attention ongenetic diversity and the evolutionary continuum from populations to species.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
