A family affair… Wang et al assessed transcriptional regulation of well-known immune-related subfamilies of OsPRRs, OsRLCKs, and OsTFs, & identified several novel subfamilies that contribute to pathogen perception & plant defense doi.org/10.1093/pcp/... #PlantScience #PlantImmunity

A schematic overview of PRR, RLCK, and TF DEGs in the rice plant and suspension cell experiments. (Panel a) Rice plants were infected with M. oryzae and collected at 1, 2, and 3 dpi. Rice suspension cells were treated with chitin and collected at 1, 3, 6, and 12 hpt. (Panel b) OsRLK, OsRLP, OsRLCK, and OsTF DEGs categorized into upregulated DEGs, downregulated DEGs, or up- and down-regulated DEGs.

Designer proteins👓 Through creation of artificial pentatricopeptide repeat (PPR) proteins, Mathieu et al. show that the PPR repeat scaffold is sufficient to efficiently stabilize processed RNAs in #chloroplasts, while the N and C terminals are dispensable doi.org/10.1093/pcp/... #PlantScience

Schematic representation of the artificial dPPRrbcL protein,
designed to bind the 5 region of the rbcL mRNA. The construct includes a CTP, an NTD, 13 artificial PPR motifs recognizing the rbcL 5
UTR (from −69 to −57 relative to the start codon), and a C-terminal 3 × HA tag. The transcriptional start site and previously mapped in
vivo 5 ends of the rbcL transcript are indicated. (b) Schematic diagram showing the structures of the truncated variants lacking either or both terminal domains:
ΔNTD/CTD (both domains deleted), ΔNTD (lacking the NTD), and ΔCTD (lacking the CTD), with their approximate molecular weights.
