Improving cold tolerance in rice: How wrky53 mutants give cold stress the boot
The Plant Cell: In a NutshellTang et al. examine the function of the transcription factor WRKY53 in cold stress tolerance at the booting stage in rice.
Background: Rice (Oryza sativa L.) is a staple food for over half of the global population. Cold stress at the booting stage leads to serious yield losses and has become a major…
Auxin–ethylene interactions in rice roots
The Plant Cell: In a NutshellZhou et al. explore the links between ethylene and auxin responses in rice. https://doi.org/10.1093/plcell/koac250
Background: The phytohormones ethylene and auxin play important roles in developmental regulation and environmental acclimation in plants. Ethylene promotes the accumulation of the…

A plant unique ESCRT component functions in peroxisome-mediated lipid droplet turnover
The Plant Cell: In a NutshellHuang et al. demonstrate a novel role–and the underlying mechanism–for FREE1 in regulating LD turnover. Plant Cell. https://doi.org/10.1093/plcell/koac195
Background: Lipid droplets (LDs) are major reservoirs providing energy and lipids for seedling establishment. In vascular plants, the peroxisome-localized…
SlCLV3-WUS regulates tomato flower abscission
The Plant Cell: In a NutshellCheng et al. show that Low-light conditions stimulate the SlCLV3-SlWUS signaling module and regulate phytohormone homeostasis to induce abscission https://doi.org/10.1093/plcell/koac254

Utilization of photoassimilates for growth and development requires the Arabidopsis copper deficiency response regulator SPL7
The Plant Cell: In a NutshellBy Anna Schulten and Ute Krämer, Department of Molecular Genetics and Physiology of Plants, Ruhr University Bochum, Germany
Schulten and colleagues explore the reasons behind the growth defects seen in the spl7 mutants, and discover that they cannot utilize the plentiful sugars they accumulate.
Background:…
