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

FEBS 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.

SEGREGATION DISTORTION AND CROSSING OVER IN MALES OF DROSOPHILA ANANASSAE. I: PRELIMINARY GENETIC ANALYSIS

Genetics, 1971
ANDLER and NOVITSKI (1957) proposed the term “meiotic drive” (or segregation distortion) to describe a condition which leads to unequal segregation of the two alleles present in a heterozygote in consequence of certain aberrant mechanisms during meiosis.

Genetic Diversity and Differentiation at Structurally Varying MHC Haplotypes and Microsatellites in Bottlenecked Populations of Endangered Crested Ibis

Cells, 2019
Investigating adaptive potential and understanding the relative roles of selection and genetic drift in populations of endangered species are essential in conservation.

Metastable Evolutionary Dynamics: Crossing Fitness Barriers or Escaping via Neutral Paths?

, 1999
We analytically study the dynamics of evolving populations that exhibit metastability on the level of phenotype or fitness. In constant selective environments, such metastable behavior is caused by two qualitatively different mechanisms. One the one hand,

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

A wheat chromosome segment substitution line series supports characterization and use of progenitor genetic variation

The Plant Genome
Genome‐wide introgression and substitution lines have been developed in many plant species, enhancing mapping precision, gene discovery, and the identification and exploitation of variation from wild relatives.

The role of plastid genes in a heterosis effect and the formation of morphophysiological traits in sunflower plants

Труды по прикладной ботанике, генетике и селекции, 2020
Background. The problem of nucleus-plastid interactions is obviously of theoretical and practical importance. However, the lack of knowledge in this area of plant research is, for the most part, caused by difficulties in isolating the contribution of the

Organisation, sequence diversity and evolution of a disease-resistance gene cluster in coffee tree (Coffea l.) [PDF]

, 2008
Pathogen resistance (R) genes of the NBS-LRR class (for nucleotide binding site and leucine-rich repeat) are found in all plant species and confer resistance to a diverse spectrum of pathogens.

Comparative population structure of Plasmodium malariae and Plasmodium falciparum under different transmission settings in Malawi [PDF]

, 2011
<b>Background:</b> Described here is the first population genetic study of Plasmodium malariae, the causative agent of quartan malaria. Although not as deadly as Plasmodium falciparum, P.
