MAC3 Proteins Regulate MicroRNA Biogenesis

Li et al. uncovered the roles of MAC3 in miRNA biogenesis in Arabidopsis. Plant Cell (2018). By Shengjun Li and Bin Yu Background: microRNAs (miRNAs) are tiny RNA molecules that regulate gene expression. Plants use miRNAs to control development and physiology. Consequently, understanding of the…

Underground Functions of GIF Genes

Ercoli et al. investigate how GIF genes control root development https://doi.org/10.1105/tpc.17.00856 By María Florencia Ercoli and Javier Palatnik Background: Plants, unlike animals, have the ability to generate new organs throughout their life cycle. This capacity relies on meristems, which…

Maize Tassel Architecture

Zhang et al. show that GIF1 regulates the determinacy of meristems and controls tassel architecture in maize. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00791 Background: Plant architecture results from a balance of indeterminate and determinate cell fates. Cells with indeterminate fates…

Gene Expression Study Reveals Distinct Virulence Modules of Corn Smut Fungus

Lanver et al. investigate fungal gene expression during corn infection by Ustilago maydis. The Plant Cell (2018) https://doi.org/10.1105/tpc.17.00764 By Daniel Lanver and Regine Kahmann Background: The corn smut fungus Ustilago maydis is a model organism for studying how fungi can colonize living…

Meiotic Crossover Formation

Kurzbauer et al. discover a role for the Fanconi anemia D2 plant homogue in promoting meiotic crossover formation. https://doi.org/10.1105/tpc.17.00745 by Marie-Therese Kurzbauer and Peter Schlögelhofer Background: Meiosis is a specialized cell division and generates the basis for genetic diversity…

A Unified Maize Endosperm Regulatory Network

Feng et al. show that the transcription factor O11 is a master regulatory protein in endosperm development. Plant Cell https://doi.org/10.1105/tpc.17.00616. By Fan Feng and Rentao Song Background: Maize is one of the most important crops both for food and industry. The main nutrients of maize…

Saving Algae from Environmental Stresses

Du et al. investigate an important protein that regulates photosynthesis under stress. Plant Cell. https://doi.org/10.1105/tpc.17.00446.                                                                               Background:…

Nodule Symbiosis: Cleavage of Bacterial Signals Affects Nodule Shape

Cai et al. investigate the function of a Medicago truncatula enzyme (MtNFH1) that cleaves nodulation signals of symbiotic Sinorhizobium meliloti bacteria. Plant Cell (2018). https://doi.org/10.1105/tpc.17.00420. By Jie Cai, Zhi-Ping Xie and Christian Staehelin Background: Nitrogen-fixing rhizobia…

Conservation of Genomic Imprinting during Wheat Polyploidization

Yang et al. discover conservation of genomic imprinting between closely related Triticum and Aegilops species. https://doi.org/10.1105/tpc.17.00837 By Guanghui Yang and Mingming Xin Background: Genomic imprinting causes genes to be differentially expressed depending on their parent-of-origin, which…
