Article Synopsis
- The text discusses a pathogen that infects various economically important crops, including citrus, and highlights the importance of understanding its virulence mechanisms, particularly in relation to resistant and susceptible plant varieties.
- The research utilized advanced techniques like MALDI-MSI and UHPLC/ESI-Q-TOF-MS to analyze the production of secondary metabolites in the pathogen and how they are affected by extracts from different plant species.
- Findings showed that plant extracts influenced the pathogen's growth, morphology, and zoospore behavior, while various metabolites were identified, suggesting potential roles in the interaction and virulence of the pathogen, warranting further functional analysis.
The essential tea tree oil (TTO) derived from plant is widely used as a biopesticide to protect crops from several plant-pathogens. Its activity raised queries regarding its ability to, not only act as a bio-fungicide or bio-bactericide, but also systemically inducing resistance in plants. This was examined by TTO application to banana plants challenged by f.

P. parasitica causes disease in a wide range of host plants, however the role of CRN effectors in these interactions remains unclear.

Phytophthora parasitica, a hemibiothrophic oomycete pathogen and the causal agent of citrus root rot and gummosis, interacts differently with Citrus sunki and Poncirus trifoliata, two commonly favored citrus rootstocks that are recognized as susceptible and resistant, respectively, to P. parasitica.

To develop novel control strategies for disease prevention in citrus, it is essential to expand and consolidate our knowledge of the molecular interaction of citrus plants with their pathogens.
Scope: This review provides an overview of our understanding of citrus plant immunity, focusing on the molecular mechanisms involved in the interactions with viruses, bacteria, fungi, oomycetes and vectors related to the following diseases: tristeza, psorosis, citrus variegated chlorosis, citrus canker, huanglongbing, brown spot, post-bloom, anthracnose, gummosis and citrus root rot.
Background: The present study aimed to identify and characterize the presence of bacteria carried by ants, and check the distribution of these ants in the physical confines of a medium-sized hospital in São Paulo county, Brazil.
Methods: The ants were collected from March 2012 to February 2013. Attractive non-toxic baits were used to catch the ants, and the sectors considered for the study were medical wards, outdoor areas, obstetric unit, reception area, kitchen, surgical centres, paediatric clinic and intensive care unit.
