Cross-species transmission and PB2 mammalian adaptations of highly pathogenic avian influenza A/H5N1 viruses in Chile

The paper tracks the emergence and mammalian adaptation of H5N1 HPAIV in Chile, identifying key mutations in the PB2 gene associated with cross-species transmission.

Emergence and rapid dissemination of highly pathogenic avian influenza virus H5N1 clade 2.3.4.4b in wild birds, Chile.

The paper reports the emergence and spread of H5N1 clade 2.3.4.4b in Chile, identifying two viral clusters through genomic sequencing of wild bird samples.

A new gene encoding a cytosolic glutamine synthetase in pine is linked to developing tissues

The paper identifies a new pine GS1 gene, PpGS1b.2, and shows it has distinct kinetic properties and potential roles in plant development compared to GS1b.1.

A revised view on the evolution of glutamine synthetase isoenzymes in plants

This study reclassifies plant glutamine synthetase isoenzymes into three clusters and explores their evolutionary origins and functional roles in nitrogen assimilation.

Ammonium regulates the development and architecture of pine roots through hormonal crosstalk and differential expression of transcription factors in the apex

The paper investigates how ammonium affects pine root development by altering transcription factors and phytohormone distributions in the root apex.

Epitranscriptome changes triggered by ammonium nutrition regulate the proteome response of maritime pine roots

The paper examines how ammonium nutrition alters the epitranscriptome in maritime pine roots, showing m6A modifications regulate translation and proteome responses.

Orange is the new white: taxonomic revision of Antarctic Tritonia species (Gastropoda: Nudibranchia)

This study revises the taxonomy of Antarctic Tritonia species using molecular and morphological data, identifying two species and highlighting color variability due to diet.

Host species determine symbiotic community composition in Antarctic sponges (Porifera: Demospongiae)

This study analyzes the microbiota of four Antarctic sponge species to show that their prokaryote communities are host-specific and less diverse than surrounding seawater.

Allosteric deregulation of phenylalanine biosynthesis evolved with the emergence of vascular plants

The paper shows that type-II arogenate dehydratase (ADT) isoforms in vascular plants evolved relaxed Phe feedback inhibition, enabling higher Phe accumulation and lignin production.
