Williams-Carrier R, Chotewutmontri P, Perkel S, Rojas M, Belcher S, Barkan A
Plant Cell . 2025 Mar; PMID: 40073200
The D1 subunit of photosystem II is subject to photooxidative damage. Photodamaged D1 must be replaced with nascent D1 to maintain photosynthesis. In plant chloroplasts, D1 photodamage regulates D1 synthesis...

Wang Y, Williams-Carrier R, Meeley R, Fox T, Chamusco K, Nashed M, et al.
G3 (Bethesda) . 2024 Aug; 14(10). PMID: 39163571
The interaction of plant mitochondrial and nuclear genetic systems is exemplified by mitochondria-encoded cytoplasmic male sterility (CMS) under the control of nuclear restorer-of-fertility genes. The S type of CMS in...

Ku J, Ronceret A, Golubovskaya I, Lee D, Wang C, Timofejeva L, et al.
PLoS Genet . 2020 Apr; 16(4):e1007881. PMID: 32310948
Meiotic double-strand breaks (DSBs) are generated by the evolutionarily conserved SPO11 complex in the context of chromatin loops that are organized along axial elements (AEs) of chromosomes. However, how DSBs...

Swift K, Chotewutmontri P, Belcher S, Williams-Carrier R, Barkan A
Plants (Basel) . 2020 Feb; 9(2). PMID: 32041317
Bacterial ribosome hibernation factors sequester ribosomes in an inactive state during the stationary phase and in response to stress. The cyanobacterial ribosome hibernation factor LrtA has been suggested to inactivate...

Chotewutmontri P, Williams-Carrier R, Barkan A
Plants (Basel) . 2020 Jan; 9(2). PMID: 31991763
Photosystem II (PSII) in chloroplasts and cyanobacteria contains approximately fifteen core proteins, which organize numerous pigments and prosthetic groups that mediate the light-driven water-splitting activity that drives oxygenic photosynthesis. The...
6.
Watkins K, Williams-Carrier R, Chotewutmontri P, Friso G, Teubner M, Belcher S, et al.
Plant J . 2019 Dec; 102(2):369-382. PMID: 31793101
Synthesis of the D1 reaction center protein of Photosystem II is dynamically regulated in response to environmental and developmental cues. In chloroplasts, much of this regulation occurs at the post-transcriptional...

McDermott J, Watkins K, Williams-Carrier R, Barkan A
Plant Cell . 2019 May; 31(8):1723-1733. PMID: 31123048
Pentatricopeptide repeat (PPR) proteins bind RNA via a mechanism that facilitates the customization of sequence specificity. However, natural PPR proteins have irregular features that limit the degree to which their...

Rojas M, Yu Q, Williams-Carrier R, Maliga P, Barkan A
Nat Plants . 2019 May; 5(5):505-511. PMID: 31036912
The engineering of plant genomes presents exciting opportunities to modify agronomic traits and to produce high-value products in plants. Expression of foreign proteins from transgenes in the chloroplast genome offers...

Jiang J, Chai X, Manavski N, Williams-Carrier R, He B, Brachmann A, et al.
Plant Cell . 2019 Apr; 31(6):1308-1327. PMID: 30962391
A key characteristic of chloroplast gene expression is the predominance of posttranscriptional control via numerous nucleus-encoded RNA binding factors. Here, we explored the essential roles of the S1-domain-containing protein ()/...

Williams-Carrier R, Brewster C, Belcher S, Rojas M, Chotewutmontri P, Ljungdahl S, et al.
Plant J . 2019 Mar; 99(1):56-66. PMID: 30844105
The expression of chloroplast genes relies on a host of nucleus-encoded proteins. Identification of such proteins and elucidation of their functions are ongoing challenges. We used ribosome profiling to revisit...
