Here, Schwarze et al. reveal how plant cells match protein quality control to changing rates of protein production through a functional link between TOR kinase signalling and NOT4 E3 ubiquitin ligases

La vitesse de fleurissement et la quantité de pétales produits par les plantes à fleurs dépendent d’un mécanisme bien orchestré mais complexe. Des chercheurs sont parvenus à déterminer les acteurs et ...

How do cells ensure that complex, multidomain proteins fold correctly? Luo et al. reveal a self-contained solution. The 3′UTR of an mRNA co-translationally chaperones the protein it encodes, preventin...

RSH enzymes (RelA/SpoT homologs) synthesize ppGpp (guanosine tetra-/pentaphosphate) in plastids, regulating organelle function. More importantly, whether ppGpp acts as a simple rheostat on immune outp...

Plants perceive neighboring vegetation through an enrichment of far-red light (shade) in the environment. These changes in light quality trigger molecular and physiological responses aimed at outgrowi...

Transcription in chloroplasts depends on the Plastid-Encoded RNA polymerase (PEP), a bacterial-derived enzyme whose catalytic core remains encoded by the highly reduced genome inherited from the cyano...

The conserved MBS1 protein assembles into chloroplast-associated condensates to sense singlet oxygen and shield chloroplasts against excess light penetration.

TAM regulates the translation of meiotic cell cycle genes under heat stress to prevent premature meiotic exit and ensure ploidy consistency in the natural

Chloroplast plastoglobules act as nitrogen-assimilation hubs in maize, with key enzymes enhancing nitrogen-use efficiency and offering new strategies for developing high-yield, sustainable crops.

Agrobacterium-mediated transformation is the dominant method for plant transgenesis, yet it frequently produces multi-copy, structurally complex T-DNA insertions associated with transgene silencing, u...

In bacteria, protein mistranslation can improve stress tolerance. Mitochondria and plastids evolved from bacteria and use a prokaryotic-type expres...

Background: Sample disruption and homogenization are critical steps in numerous biological extraction procedures (i.e., DNA, RNA, or protein isolation). These steps are often performed manually which ...

Transfer RNAs (tRNAs) are essential components of the translational machinery. Their abundance and diversity shape decoding capacity and protein synthesis efficiency and accuracy. Because tRNA abundan...

Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to ....

Translation initiation subunit eIF3E helps balance protein production by coordinating opposing genetic cis-elements, affecting pollen tube growth and the s

Plastids, photosynthetic organelles in plants and algae, originated from cyanobacterial endosymbiosis. Here, Shrestha et al. use metagenomics to expand plastid diversity and provide evidence for two i...
