Polygalacturonase (PG), one of the hydrolases responsible for cell wall pectin degradation, is involved in organ consenescence and biotic stress in plants. PG1 is composed of a catalytic subunit, PG2, and a non-catalytic PG1β subunit. OsBURP16 belongs to the PG1β-like subfamily of BURP-family genes and encodes one putative PG1β subunit precursor in rice… (More)
DNA phosphorothioate (PT) modification, with sulfur replacing a nonbridging phosphate oxygen in a sequence and stereo specific manner, is a novel physiological variation in bacteria. But what effects on DNA properties PT modification has is still unclear. To address this, we prepared three double-stranded (ds) DNA decamers, d(CG(PX)GCCGCCGA) with its… (More)
Two porcine epidemic diarrhea virus (PEDV) strains, JSLS-1/2015 and JS-2/2015, were isolated from piglets with watery diarrhea in South China. Two genomic sequences were highly homologous to the attenuated DR13 strain. Furthermore, JSLS-1/2015 contains a 24-amino-acid deletion in open reading frame 1b, which was first reported in PEDV isolates.
In this study, we constructed for the first time a full-length cDNA clone of pig-original bovine viral diarrhea virus 2 (BVDV-2) strain SH-28, modified the cDNA clone (pASH28) for mutant pASHΔNpro and derived virus strain vASHΔNpro by deleting the genomic region encoding the Npro polypeptide, and examined significance of protein Npro for antiviral responses… (More)
Stress-associated proteins (SAPs) containing the A20/AN1 zinc-finger domain play important roles in response to both biotic and abiotic stresses in plants. Nevertheless, few studies have focused on the SAP gene family in cotton. To explore the distributions and expression patterns of these genes, we performed genome-wide identification and characterization… (More)
To the editor: A recent outbreak of a novel avian-origin reassortant influenza A (H7N9) virus in eastern China has raised great concerns owing to the rapidly progressive lower respiratory tract infections in infected individuals. As of August 1, 2014, a total of 151 humans infections of H7N9 (resulting in 45 deaths) in China have been reported to the World… (More)
