Karrikins and Strigolactone Signaling in Monocots

/in , , , /by

Zheng et al. demonstrate how monocot plants sense karrikin, a smoke-derived chemical. Plant Cell https://doi.org/10.1105/tpc.20.00123 By J Zheng, K Hong, L Zeng, S Kang and G Xiong Background: Seedling emergence in rice depends mainly on mesocotyl elongation, which is precisely regulated by the integration of developmental signals and environmental stimuli. Karrikins are small molecules found […]

A Balancing act between virus replication and transcription

/in , , , /by

Gao et al. demonstrate that CK1 regulates plant cytorhabdovirus infections in both plants and insects. Plant Cell https://doi.org/10.1105/tpc.20.00369   By Qiang Gao and Xian-Bing Wang, China Agricultural University  Background: Phosphorylation is a widespread post-translational modification of cellular proteins in eukaryotic cells.

The Multifaceted Roles of Autophagy in Fixed-carbon Starvation

/in , , , /by

McLoughlin et al. uncover the critical roles of autophagy in recycling amino acids and nitrogen-rich nucleotides, adjusting respiratory substrates, and the retention of assimilated nitrogen in maize during fixed-carbon starvation. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00226  Background: Autophagy is a central recycling system that helps remove unnecessary or damaged intracellular material, including organelles, protein complexes, lipid […]

Correcting organellar spelling with RNA editors
