Fan et al. investigate the proteins involved in DNA base excision repair https://doi.org/10.1093/plcell/koae052 By Tianyi Fan and Yan Zhu Background: DNA bases are susceptible to damage from environmental factors such as UV light or reactive oxygen species. Base excision repair (BER) can eliminate…

He et al. explore how histone H1 drives the formation of heterochromatin foci. https://doi.org/10.1093/plcell/koae034 Xiaoqi Feng, Institute of Science and Technology Austria Background: To fit into the nucleus, DNA is densely packaged into structures known as nucleosomes. These nucleosomes…

OsLESV cooperates with FLO6 to modulate starch biosynthesis and endosperm development Yan, Zhang, Wang et al. identify OsLESV–FLO6 as a non-enzymatic molecular module responsible for starch biosynthesis and endosperm development. https://doi.org/10.1093/plcell/koae006 By Haigang Yan, Wenwei…

Background: Photosystem I (PSI) is a large pigment-protein complex that participates in photosynthetic electron transfer. While its structure is well resolved, its assembly pathway is less clear.  A set of proteins mediating the step-wise assembly of PSI subunits, known as PSI assembly factors, has…
