Kim et al. investigate the role of a heat shock protein in thermotolerance. https://doi.org/10.1093/plcell/koac351 By Minsoo Kim and Elizabeth Vierling at UMass Amherst Background: Plants can survive heat stress by producing heat shock proteins (HSPs) that protect and rescue other proteins. One HSP, the ATP-dependent protein disaggregase HSP101, is essential for tolerance to severe heat. […]
Chen et al. demonstrated that installing a bacterial-type fast Rubisco into tobacco chloroplasts to support photosynthesis. The Plant Cell (2023). https://doi.org/10.1093/plcell/koac348 By Taiyu Chen and Lu-Ning Liu Background: Rubisco is the key enzyme responsible for fixing CO2. However, due to its intrinsically low catalytic turnover rate, Rubisco represents the ultimate rate-limiting step in plant photosynthesis. […]

Ting Pan et al. reveal a molecular mechanism to deal with DNA replication stress in Arabidopsis. The Plant Cell (2022). Ting Pan, Shan Gao, Xiaoyu Cui, Lili Wang and Shunping Yan College of Life Science and Technology, Huazhong Agricultural University, Wuhan, Hubei 430070, China Background: DNA replication is a fundamental process for all organisms. Many […]
Deslandes-Hérold et al. explore the integration of the PRK/Rubisco shunt into green embryo photosynthesis and metabolism. Gabriel Deslandes-Hérold, Melanie R. Abt, and Samuel C. Zeeman, ETH Zurich Background: Light promotes the accumulation of storage lipids during development of oilseeds with green embryos. This has been explained by embryonic photosynthesis generating cofactors that can power an […]
Author et al. explore the genes involved in making stomata in a temperate grass. Katelyn Hansen-McKown and Dominique Bergmann, Stanford University School of Medicine, Stanford University and Howard Hughes Medical Institution. Background: Plants are essential players in global carbon and water cycling. The structures central to this role are stomata, pores on leaf surfaces. Plants […]
Xu, Sato, et al. explore the longstanding mystery of why endosperm cellularization is essential for embryo survival and reveal a connection to dehydration responses. Background: In most angiosperms, the endosperm initiates as a coenocyte and starts to cellularize after a defined number of nuclear divisions. This process of cellularization is frequently disrupted in hybrid seeds generated […]
