How circadian changes in metabolism affect hybrid vigor

Zhi Li, Andan Zhu, et al. compare inbred and hybrid lines to explore how daily changes in metabolic pathways affect hybrid vigor. The Plant Cell https://doi.org/10.1105/tpc.20.00320  Background: Heterosis or hybrid vigor refers to the superior growth or fitness in the hybrid progeny compared to one or both parents. Heterosis is widespread and commonly used in […]

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

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, […]

MYB10 in Action

Castillejo et al. describe how independent mutations in the transcription factor MYB10 drive natural variation in strawberry color. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00474  By Cristina Castillejo and Iraida Amaya Instituto Andaluz de Investigación y Formación Agraria y Pesquera (IFAPA). Centro de Málaga.   Background: The red color of strawberry fruits results from the accumulation of […]

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

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

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

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 […]

How Rice Fights Salinity

Wang et al. demonstrate how rice alters the expression of a sodium transporter gene under salinity stress. The Plant Cell (2020). Plant Cell https://doi.org/10.1105/tpc.20.00301 By Jie Wang, Nan Nan, Ning Li, Yutong Liu, Tian-Jing Wang, Inhwan Hwang, Bao Liu and Zheng-Yi Xu Background: Excessive sodium (Na+) accumulates in irrigated fields and harms rice during its […]

Balancing phosphorus and nitrogen during phosphate starvation

Wang et al. explore how plants increase Pi uptake and reduce nitrate uptake during Pi starvation. Plant Cell https://doi.org/10.1105/tpc.20.00361 By Xue Wang and Yi-Fang Chen State Key Laboratory of Plant Physiology and Biochemistry, College of Biological Sciences, China Agricultural University, Center for Crop Functional Genomics and Molecular Breeding, Beijing, China Background: Phosphorus (P) and nitrogen […]

Mapping the Routes of Systemic Signaling in Arabidopsis

Zandalinas et al. identify the plant tissues that mediate systemic reactive oxygen signaling in response to high-light stress in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc.20.00453 By Sara I Zandalinas and Ron Mittler University of Missouri, Columbia, MO, USA  Background: Plants constantly sense and respond to changes in their environment. These responses are not restricted to the specific […]
