Carbon metabolism shapes FtsZ levels and cell division in the cyanobacterium Anabaena PCC 7120 www.nature.com/articles/s42... #jcampubs

Carbon metabolism shapes FtsZ levels and cell division in the cyanobacterium Anabaena PCC 7120 - Communications Biology

This study provides evidence on how carbon metabolism regulates cell division among cyanobacteria. Manipulation of the TCA pathway directly impacts the FtsZ-dependent cell division by regulating its expression via the transcriptional factor NtcA.

Pass it along.
Pubmed was the only reliable source for scientific articles. Guess we can adapt to this database . So much winning!!!🤨

🚨 The US government has stopped the funding PubMed, one of the most comprehensive databased of biomedical literature.

Try using Europe PMC (europepmc.org) — the European alternative to PubMed with 46M+ articles.

How do cyanobacteria glide in sync? 🌀

New research on Fluctiforma draycotensis shows that filament movement relies on tightly coordinated cellular forces, and when that coordination breaks down, the filaments twist and buckle.

À great research topic. The niche-research-field is killing science. Every unanswered question is a wide research field, and this association is a beautiful interaction to understand. Congrats! I would love collaborating with you on it.
