Targeting of plasmodesmal proteins requires unconventional signals

Gabriel Robles Luna, Jung-Youn Lee and colleagues discover that proteins carry targeting signals that send them to plasmodesmata, but these signals show no sequence conservation. https://doi.org/10.1093/plcell/koad152 Gabriel Robles Luna1, Jiefu Li3, Xu Wang1, Li Liao2,3, and Jung-Youn Lee1,2,4*         …

Review: Rapid auxin signaling: Unknowns old and new

You might think you’ve read enough about auxin, but I recommend you take this opportunity to read one more article, this very interesting and enjoyable review by Fielder and Friml. Auxin has figured prominently in both the classical and molecular eras of plant biology. However, the exciting findings…

Control of guard cell aperture by protein kinase CIPK23

Guard cells are responsible for the opening and closing of stomata through changes in osmotic content and turgor pressure. These changes occur in response to activation or inactivation of ion transport proteins that are in turn regulated by protein kinase and phosphatase networks. The kinase network…
