Commentary: Plastid establishment did not require a chlamydial partner
Primary plastids descend from the cyanobacterial endosymbiont of an ancient eukaryotic host, but the initial selective drivers that stabilized the association between these two cells are still unclear. One hypothesis that has achieved recent prominence suggests that the first role of the cyanobiont was in energy provision for a host cell whose reserves were being depleted by an intracellular ch...

متن کاملCommentary: Plant Auxin Biosynthesis Did Not Originate in Charophytes
A commentary on Plant auxin biosynthesis did not originate in charophytes The TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAA) family of aminotransferases and the YUCCA (YUC) family of flavin monooxygenases are required for the biosynthesis of auxin (Mashiguchi et al., 2011). However, the origin of TAA-YUC auxin biosynthesis pathway is under hot debate recently (Wang et al., 2014; Yue et al., 2...
متن کاملPorcine epidemic diarrhea virus (PEDV) co-infection induced chlamydial persistence/stress does not require viral replication
Chlamydiae may exist at the site of infection in an alternative replicative form, called the aberrant body (AB). ABs are produced during a viable but non-infectious developmental state termed "persistence" or "chlamydial stress." As persistent/stressed chlamydiae: (i) may contribute to chronic inflammation observed in diseases like trachoma; and (ii) are more resistant to current anti-chlamydia...
متن کاملPlastid-bearing sea slugs fix CO2 in the light but do not require photosynthesis to survive.
Several sacoglossan sea slugs (Plakobranchoidea) feed upon plastids of large unicellular algae. Four species--called long-term retention (LtR) species--are known to sequester ingested plastids within specialized cells of the digestive gland. There, the stolen plastids (kleptoplasts) remain photosynthetically active for several months, during which time LtR species can survive without additional...
