Químicoreceptor of Salmonella typhimurium?

AI Thread Summary
The discussion centers on the receptors involved in the chemotaxis of Salmonella typhimurium. Participants clarify that Salmonella uses specific receptors to detect stimuli, which allows it to determine positive or negative signals. The conversation highlights the importance of 'che' genes, which are crucial for chemotaxis and show homology with E. coli. Several scientific articles are referenced for further reading on the subject, providing valuable resources for understanding the mechanisms of Salmonella's chemotactic response.

do you mean 'chemotaxis'?
Yes, jaja sorry, i mean i know that sallmomena detects an stimule with receptors but I don't konow how receptors detect if is a positive or negative stimule

Have you search the literature? The relevant genes appear to be the 'che' genes, and there is homology between E. Coli and Salmonella. A quick search yields:

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
