Type 1 secretion system and effectors in Rickettsiales
Frontiers in Cellular and Infection Microbiology, 2023 Obligate intracellular bacteria in the order Rickettsiales are transmitted by arthropod vectors and cause life-threatening infections in humans and animals. While both type 1 and type 4 secretion systems (T1SS and T4SS) have been identified in this group,

Unifying microorganisms and macrograzers in intertidal rocky shore ecological networks. [PDF]
EcologyAbstract Over the past decades, our understanding of the vital role microbes play in ecosystem processes has greatly expanded. However, we still have limited knowledge about how microbial communities interact with larger organisms. Many existing representations of microbial interactions are based on co‐occurrence patterns, which do not provide clear ...
