OsPIL15 Regulates Stomatal Aperture by Coordinating Red Light and Abscisic Acid Signaling
The Plant Cell: In a NutshellLi et al. discover that OsPIL15 interacting with OsHHO3 forms the OsPIL15-OsHHO3 transcription factor complex to promote the binding of OsPIL15 to the promoter regions of OsABI5 and then reduce stomatal aperture through the ABA signaling pathway https://doi.org/10.1093/plcell/koac244

A fresh mechanism for drought tolerance in apple
The Plant Cell: In a NutshellNiu, Jiang, Cao et al. discover the role of a ferredoxin-NADP+ oxidoreductase gene in drought tolerance in apple.
Background: Global climate change and rapid population growth have been increasing the shortage of water resources, enhancing the effects of natural disasters such as drought. Drought…
Brassinosteroids in the organization of rice internodes
The Plant Cell: In a NutshellNiu et al. discovered how the organization of rice internodes is regulated by the steroid hormone brassinosteroid. The Plant Cell (2022)
By Mei Niu and Hongning Tong
Background: Rice culms consist of 5–7 internodes and the length of these internodes determines plant height and resistance to wind,…

Structure-based RNA transport into the nucleus
The Plant Cell: In a NutshellJunfei Ma, Shachinthaka D. Dissanayaka Mudiyanselage and Ying Wang (Department of Biological Sciences, Mississippi State University)
Background: During the course of evolution, eukaryotic cells gained a nuclear envelope to protect their genomes. However, to coordinate diverse biological processes,…
A sensor for inhibition of symbiosis when phosphate is plentiful
Research, The Plant Cell: In a NutshellLiao et al. describe a sensor complex that coordinates phosphate signaling and arbuscular mycorrhiza symbiosis.
Background: Arbuscular mycorrhiza (AM) symbiosis is a widespread phenomenon in terrestrial plants that improves the acquisition of mineral nutrients. Successful symbiosis with AMs enhances…
