Flagellar system translocates T3SS effectors critical for Salmonella infection

Type 3 secretion system (T3SS) injectisomes, the essential virulence factors of many bacterial pathogens, are thought to have evolved from the flagellar T3SS. Despite their high degree of structural s...

This brochure is, undoubtedly, a memento of one of the most beautiful moments I’ve had so far in my professional life 🥲. It was created by students of a small school in Pará state, Brazil. High school students shared with familiars (small farmers) what they learned about the cassava 'witches broom'.

Cacao trees planted in fields infested with Cassava Witches' Broom Disease can exhibit similar symptoms. Supposedly, Rhizoctonia theobromae from cassava may also be a causal agent of disease in South American cacao.

Iranians are experiencing a collective trauma. Thousands have been killed/injured in recent events, the economy is crippled & the threat of a wider conflict is real. This is especially difficult for those living in Iran, as many have lost (or fear losing) loved ones. www.nature.com/articles/d41...

Four months ago, I shared this post. This week, I was at a field day representing Embrapa in a strategic meeting to discuss Cassava Witch's Broom. I continue to advocate for collaborative research that integrates farmers' observations with scientific data to safeguard our crops. 🌱🧪

some philosophers use biological science concepts with mastery; some others do not. I was reviewing a quote suggesting an opposition between symbiosis and Darwinian evolution. do some of you agree with it? 🤔
