Zhang et al. investigate the regulation of apical hook development in Arabidopsis thaliana. The Plant Cell (2018). https://doi.org/10.1105/tpc.18.00018. By Xing Zhang, Yichuan Wang and Hongwei Guo. Background: For sessile plants, survival in dynamic nature is never easy! The very first challenge…

Zhang et al. show that a single-nucleotide polymorphism in a hairpin RNA promoter contributes to Alternaria alternata leaf spot resistance in apple and could serve as a marker to distinguish susceptible versus resistant apple cultivars. https://doi.org/10.1105/tpc.18.00042. Background: Apple Alternaria…

Zhang et al. investigate the assembly of a molecular motor that produces cellular ATP in chloroplasts https://doi.org/10.1105/tpc.18.00075. By Lin Zhang, Lianwei Peng and Jean-David Rochaix Background: The F-type ATP synthase produces nearly all of the cellular ATP, the universal energy currency…

Background: Chloroplasts are the major powerhouse of plant and algal cells, where photosynthesis—the conversion of carbon dioxide into organic compounds using sunlight energy—occurs. Chloroplasts are also where important cell components (such as membrane lipids and pigments) and energy-rich compounds…

Richardson et al. explore the molecular topology of the chloroplast transit peptide and its nucleotide-dependent movement within the chloroplast protein import channel. Plant Cell https://doi.org/10.1105/tpc.18.00172. By Lynn GL Richardson and Danny J Schnell Background: Chloroplasts, the site…

Franck et al. demonstrate that protein phosphatases ATUNIS1 and 2 negatively regulate cell wall integrity in pollen tubes and root hairs of Arabidopsis. Plant Cell (2018). https://doi.org/10.1105/tpc.18.00284 By C. M. Franck, J. Westermann, S. Bürssner, R. Lentz, D. Lituiev, and A. Boisson-Dernier Background:…

Higashi et al. investigate the function of a heat-inducible lipase in Arabidopsis thaliana. Plant Cell (2018). https://doi.org/10.1105/tpc.18.00347 By Yasuhiro Higashi and Kazuki Saito Background: Land plants suffer from high-temperature stress, exacerbated by climate changes in recent years.…

Liao et al. performed comparative phylogenomic analysis on rice centromeres. Plant Cell (2018). https://doi.org/10.1105/tpc.18.00163 By Yi Liao and Mingsheng Chen Background: Centromeres are necessary for faithful chromosome segregation in eukaryotic organisms. The genomic regions conferring centromere…
