Liu et al. demonstrate that EIJ1 acts as a key repressor of plant immunity. Plant Cell. https://bit.ly/37MF1tg By Hailun Liu, Yuge Li and Xingliang Hou, South China Botanical Garden, Chinese Academy of Sciences Background: Plants have evolved a complicated network to modulate the immune response.…

By Dolf Weijers In 2022, The Plant Cell will publish a Focus Issue on Plant Cell Biology. This will only be the second Focus Issue (FI) to be published in the journal, after the inaugural FI on the Biology of Plant Genomes, to appear in 2021. (Many years ago, the journal occasionally published…

Herrmann et al. uncover the role of KINESIN-12E in the rapid alignment of chromosomes during cell division.

It's not just human relationships that may require a chaperone to prevent inappropriate interactions. Numerous proteins in organisms from Escherichia coli to us, especially hydrophobic membrane proteins, also require chaperones in aqueous environments to prevent inappropriate interactions such as aggregation…

Tonosaki et al. explore how the Polycomb Repressive Complex 2 component EMBRYONIC FLOWER2a represses rice endosperm development both before and after fertilization. The Plant Cell (2020) https://bit.ly/33DQdqW By Kaoru Tonosaki and Tetsu Kinoshita Iwate University and Yokohama City University   Background:…

In plants, small interfering RNAs (siRNAs) serve as key regulators of gene expression. While 24-nucleotide (nt) siRNAs are produced by DCL3 and mediate transcriptional silencing of transposons and pericentromeric chromatin through RdDM (Borges and Martienssen, 2015), 22-nt siRNAs are processed by DCL2…

Klasek, Inoue, and Theg show how the chloroplast chaperonin Cpn60 binds Plastidic type I signal peptidase 1 in the chloroplast stroma and delivers it to the cpSecI translocon for targeting to the thylakoid membrane. Plant Cell https://doi.org/10.1105/tpc.20.00309 By Laura Klasek, University of California,…
