Wang et al. reveal the wide occurrence and biological function of N4-acetylcytidine in plant mRNA. https://doi.org/10.1093/plcell/koad189 Huijie Liu and Mingjia Chen College of Life Sciences, Nanjing Agricultural University, Nanjing 210095, P.R. China Background: Eukaryotic mRNA harbors more than 10 different chemical modifications, most of which are involved in many cellular activities such as RNA processing, […]
Bentham, De la Concepcion et al. fine-tuned a plant immune receptor pair to allow for engineering new specificities while avoiding autoactivation. https://doi.org/10.1093/plcell/koad204 Adam R Bentham, Mark J Banfield Department of Biochemistry and Metabolism, John Innes Centre, Norwich Research Park, Norwich, NR4 7UH, UK Background: Plants use specialized intracellular immune receptors called nucleotide-binding leucine-rich repeat (NLR) […]
Liu et al. identify two proteins that repress flowering by acting on the florigen activation complex. https://doi.org/10.1093/plcell/koad190 Background: Timely flowering is critical for plant reproductive success. FLOWERING PROMOTING FACTOR1 (FPF1), a small protein without any known domains, has been shown to promote flowering in several plants, including Arabidopsis (Arabidopsis thaliana), tobacco (Nicotiana tabacum) and rice […]
