Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Use of cumulative incidence of novel influenza A/H1N1 in foreign travelers to estimate lower bounds on cumulative incidence in Mexico [PDF]

, 2009
Background: An accurate estimate of the total number of cases and severity of illness of an emerging infectious disease is required both to define the burden of the epidemic and to determine the severity of disease. When a novel pathogen first appears,

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

New Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

Molecular–physiological model integration revolutionizes cereal flowering prediction

New Phytologist, Volume 249, Issue 3, Page 1373-1388, February 2026.
Summary Rapid prediction and control of flowering time is essential for breeding crops resilient to changing climates. Current models often fail to predict flowering time in new cultivars because molecular models lack integration of environmental signals, while physiological models inadequately capture the interactions of vernalization, photoperiod and

Transcriptional outputs and condensates – formation and function

New Phytologist, Volume 249, Issue 3, Page 1145-1154, February 2026.
Summary The dynamic spatiotemporal organization of macromolecules is key to the proper function of the cell, allowing the exquisite regulation of diverse processes from gene expression to enzymatic function. The formation of biomolecular condensates via phase separation (PS) acts as a general mechanism for selectively concentrating proteins, nucleic ...
