Tomato yellow leaf curl virus (TYLCV) is a significant threat to tomato cultivation globally, transmitted exclusively by the whitefly Bemisia tabaci. While previous research suggests that the TYLCV C2 protein plays a role in fostering mutualistic interactions between the virus and its insect vectors, the specific mechanisms remain unclear. In this study, we show that the C2 protein interferes with the salicylic acid (SA) defence pathway by disrupting TCP7-like transcription factor-mediated regulation of TGA2 expression.

Bacterial leaf blight (BLB) in rice, caused by the pathogen pv. , is a significant agricultural problem managed through chemical control and cultivating rice varieties with inherent resistance to the bacterial pathogen. Research has highlighted the potential of using antagonistic microbes which can suppress the BLB pathogen through the production of secondary metabolites like siderophores, rhamnolipids, and hydroxy-alkylquinolines offering a sustainable alternative for BLB management.

Many root-knot nematode (RKN) species in the genus occur in Florida, including , a species able to overcome RKN resistance genes in many crops. The distribution of these nematodes in horticultural crops is not well known. A RKN survey was conducted in South and Central Florida aiming to: (i) identify RKN infecting vegetables, fruit, and other crops; (ii) document host plants; (iii) determine RKN distribution; and (iv) gain insight on the relatedness of obtained in this study with other populations from the USA and other countries.

Antimicrobial peptides (AMPs) are recognized as one of the most ancient components of innate immunity, playing a pivotal role as the first line of host defense systems. These evolutionarily conserved molecules have been identified in various organisms, from prokaryotes to humans. AMPs establish a delicate balanced relationship between host and microbes, by simultaneously regulating the biological activities of pathogens and commensal microbes.

Electronic address:
Objectives: Emerging human pathogens of animal origin have become an increasing public health concern in recent years. The aim of this study was to investigate the transmission of group B streptococcus (GBS) clonal complex (CC) 61 strains in the southern Chinese population and analyze their genetic characteristics.
Methods: Whole-genome sequencing was performed on 693 clinical isolates of GBS collected from southern China between 2016 and 2021, and the prevalence of human CC61 isolates was investigated by genomic epidemiology.
