Microbiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.

Archives of Veterinary Science and Medicine, 2020 This study describes the occurrence of psittaciform bornavirus antigens and antibodies in tissues of birds persistently infected with psittaciform bornavirus. Analysis of serum of infected birds shows that antibodies against the P40 nucleoprotein occur most commonly, whereas antibodies to the glycoprotein are virtually completely absent.

Forest structure and connectivity drive the functional recovery of seed rain
Journal of Ecology, Volume 114, Issue 2, February 2026.Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.
