Proteotoxic stress challenges multiple organelles, but how plants coordinate proteasome capacity with organellar function remains unclear. Langin et al. reveal that endoplasmic reticulum (ER)-associat...

The 26S proteasome is essential for proteostasis and constitutes one of the most conserved molecular machineries in eukaryotes. Its homeostasis is maintained by a mechanistically conserved feedback lo...

Angiosperm seed formation requires the coordinated development of the products of double fertilization—the embryo and the endosperm. The endosperm mediates efficient nutrient transfer from surrounding...

Researchers led by Professor Iris Finkemeier from the Institute of Plant Biology and Biotechnology discovered a specific chemical mark in the ‘histone code’ of thale cress that is responsible for adap...

The U.S. government has recently convicted multiple postdocs for improper shipments of biological materials. Some see a replay of the 2018 China Initiative

When under stress, plants cut back on energy production to focus on breaking down damaged proteins.

Langin et al. find that ER-associated sorting (ERAS) directs NAC53/78 turnover and activation to couple proteasome induction with repression of photosynthesis genes, linking proteostasis to energy met...

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

He et al. identify a central regulator of condensate size and dynamics in the Chlamydomonas CO2-fixing condensate, the pyrenoid. KEY1 phosphorylates EPYC1, a linker protein for Rubisco, to maintain py...

The evolutionary diversification of an exocyst subunit was enabled by electrostatic shifts leading to its dissociation from the ancestral complex.

Processing bodies (P-bodies) are conserved ribonucleoprotein (RNP) granules central to RNA metabolism across eukaryotes. Although the mechanisms underlying their assembly are well understood, the path...

Satoru Naganawa Kinoshita, Iris Finkemeier; Letter to the editor: a robust technique for gas exchange measurements using petiole-cut Arabidopsis leaves in

Hayes and Leong et al. show that warm temperature and mild water stress synergistically enhance root elongation in Arabidopsis. The response is mediated by SnRK2.2/2.3 and COP1 through regulation of H...

Plants from the Cape Verde Islands evolved parallel mutations to protect from high salinity.

In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependen...

Zhang et al. identify a regulatory mechanism for how cells adapt to nutrient scarcity through widespread −1 ribosomal frameshifts, culminating in accelerated mRNA decay. This process, dependent on codon optimality and conserved across species, establishes direct feedback coupling the translation of new proteins with the stability of the mRNA that encodes for them.
