Yoshinari et al. demonstrate that boron-dependent poly-ubiquitination and subsequent degradation of BOR1 is coupled with its boron transport activity. Plant Cell https://bit.ly/2JYEooF By Akira Yoshinari Background: Abundance and activity of nutrient transporters are continuously tuned to both maintain nutrient availability and avoid over-accumulation of nutrients to a toxic level. Boron (B) is an essential element […]
Martinez et al. use laser capture microdissection and transcriptomic sequencing to explore how gene expression patterns regulate early morphogenesis of the compound tomato leaf. https://bit.ly/3nehiZu By Ciera Martinez, University of California, Berkeley Neelima Sinha, University of California, Davis Background: Leaf development involves cell division, expansion, and cellular specialization in specific positions along the middle to […]
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. To defend themselves against pathogens, plants employ two main regulatory […]
Herrmann et al. uncover the role of KINESIN-12E in the rapid alignment of chromosomes during cell division. The Plant Cell (2020) https://bit.ly/3lCfIzf By Arvid Herrmann Howards Hughes Medical Institute at University of Texas at Austin, Sabine Müller, Center for Plant Molecular Biology, University of Tübingen Background: Cell division is the process by which a parent […]
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 or improper folding (Gruber and Horovitz, 2016). Whereas most plasma membrane proteins in E. coli […]
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: The endosperm is a tissue that provides nourishment for embryo development in seeds and […]
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, Davis Background: As a plant grows, its chloroplasts construct their internal thylakoid […]
Wang et al. demonstrate that Arabidopsis SAUR17 promotes apical hook development and closed cotyledons in the dark by protecting the cell-expansion inhibitor PP2C-D1. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00283 By Jiajun Wang, Ning Sun, Fangfang Zhang, Renbo Yu, Haodong Chen, Xing Wang Deng, and Ning Wei Background: Many land plants start their lifecycles in the […]
Töpfer et al. created a combined leaf metabolism/gas exchange model to predict water saving and productivity in temperate climates.
