Chloroplast genes encoding photosynthesis-associated proteins are predominantly transcribed by the plastid-encoded RNA polymerase (PEP). PEP is a multi-subunit complex composed of plastid-encoded subunits similar to bacterial RNA polymerases (RNAPs) stably bound to a set of nuclear-encoded PEP-associated proteins (PAPs). PAPs are essential to PEP activity and chloroplast biogenesis, but their roles are poorly defined.

The central spikelets produce the highest number of grains, while apical and basal spikelets are less productive, and the most basal spikelets are commonly only developed in rudimentary form.

- * In a study of asterid plants, it was found that the activation of certain NLR proteins leads to the formation of oligomeric complexes, particularly with a helper NLR called NRC2, which has differing behaviors based on the activated receptor.
- * The research proposes a new activation-and-release model for NLRs in plant immunity, suggesting it operates differently than the activation mechanisms seen in mammalian paired NLRs.
Article Synopsis
- NLR proteins in plants create networks that protect against pathogens through hypersensitive cell death and innate immunity, with NRCs being key components in this defense system.
- Researchers tested 165 different pathogen effectors and found some that specifically suppress the immune response triggered by certain NRC proteins without affecting others.
- The study reveals that plant pathogens have evolved strategies to undermine the NRC immune response, suggesting a coevolutionary process that has led to the diversification of NRC proteins in the broader NLR network.
