Reductive Methylation: An Alternative to Lysine → Arginine Mutagenesis

Journal of Peptide Science, Volume 32, Issue 7, July 2026.
Replacing lysine with arginine, the standard genetic approach to eliminate amine reactivity, alters physicochemical properties and leaves the N terminus unprotected. Here, reductive methylation is characterized as a conservative chemical alternative. Complete dimethylation of human ribonucleases preserves thermostability, protein–protein interaction ...

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

Andrology, Volume 14, Issue 5, Page 1240-1248, July 2026.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Identification of haploid maize by flow cytometry, morphological and molecular markers Identificação de milho haploide por citometria de fluxo, marcadores morfológicos e moleculares

Ciência e Agrotecnologia, 2013
The development of homozygous breeding lines in maize may be accelerated through the use of haploids. Thus, the obtaining and prior identification of haploids generated by the haploid inducer lines is an important factor. The purpose of this study was to

Interaction Between Rec8 and Mis4 Is Required for Axis‐Loop Chromatin Formation and Homologous Chromosome Recombination During Meiosis

Genes to Cells, Volume 31, Issue 4, July 2026.
We identified a Mis4 cohesin loader mutant that is specifically defective in chromatin axis formation and homologous recombination while retaining normal sister chromatid cohesion. The mis4‐LR mutant, carrying the L1150S and R1159G amino acid substitutions, exhibited reduced interaction between Mis4 and Rec8, suggesting a meiosis‐specific role for the ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, Volume 600, Issue 12, Page 1782-1800, June 2026.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

Zebrafish as an Anti‐Isogenic Vertebrate Model and What It Reveals About Genetic Background and Reproducibility

BioEssays, Volume 48, Issue 6, June 2026.
Zebrafish illustrates how polygenic sex determination, maternal germline bottlenecks, and a structurally restless genome jointly destabilize deep homozygosity. These interlocking constraints make fully isogenic zebrafish lines effectively unattainable, turning this model into a natural “stress test” for assumptions about genetic background and ...
