In a nutshell: Finally connecting PI3P to autophagy and endosomal sorting

/in , , , /by

Liu et al., generate a novel collection of mutants impaired in PI3P biosynthesis and discovered new features and functions of this phosphoinositide in intracellular trafficking. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00285 By Richard S. Marshall and Richard D. Vierstra, Washington University, Saint Louis, USA Background Phosphoinositide lipids are key determinants for intracellular trafficking and membrane/organelle identity, […]

silky3 Is a Novel Transcriptional Regulator that Influences Multiple Flower Development Pathways in Maize

/in , , , /by

Luo et al. demonstrate that ectopic expression of silky3, a novel transcriptional regulator, causes pleiotropic developmental defects in maize inflorescences.. Plant Cell https://doi.org/10.1105/tpc.20.00043 By Haishan Luo, China Agricultural University, Beijing 100193, China Background: Inflorescence initiation and formation has been extensively studied in dicots, especially Arabidopsis, but underexplored in monocots such as maize. Aiming at finding […]

More complexity for root meristem development

/in , , , /by

Xiong et al. investigated the transcriptional regulation of PLT1 in Arabidopsis, which revolves around competitive and antagonistic binding of JANUS and GIF1 to IMPORTIN β4. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00108 By Feng Xiong and Sha Li, State Key Laboratory of Crop Biology, College of Life Sciences, Shandong Agricultural University Background: Spatially coordinated cell division and […]

AP-2-dependent Endocytosis of BRI1

/in , , , /by

Liu et al. demonstrate how canonical tyrosine endocytic motifs control the internalization of plasma membrane proteins by the clathrin adaptor complex AP-2. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00384.   Background: In plants, plasma membrane (PM)-resident proteins are selectively engulfed into the cell, a process called endocytosis, which is crucial for signal activation or termination. Clathrin-mediated endocytosis […]
