MAC3 Proteins Regulate MicroRNA Biogenesis
Research, The Plant Cell, The Plant Cell: In a NutshellLi 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
Research, The Plant Cell, The Plant Cell: In a NutshellErcoli 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
Research, The Plant Cell, The Plant Cell: In a NutshellZhang 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
Research, The Plant Cell, The Plant Cell: In a NutshellLanver 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…
A Unified Maize Endosperm Regulatory Network
Research, The Plant Cell, The Plant Cell: In a NutshellFeng 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…
Systemic RNA Silencing in Tobacco
Plant Physiology, Plant Physiology: On The Insidegene RNA silencing is a cellular gene regulatory mechanism that is conserved across fungal, plant, and animal kingdoms. Through sequence-specific targeting, RNA silencing can degrade mRNA for posttranscriptional gene silencing (PTGS) or modify related DNA for transcriptional gene silencing. RNA silencing…
Transcriptomics of deepwater rice (Plant Physiol)
Plant Science Research WeeklyFor most plants, becoming submerged under water can be lethal due to a restriction in gas exchange. One strategy for submergence tolerance is called an escape strategy, such as that employed by deepwater rice; the plant elongates rapidly to raise its leaves above the water level. Minami et al. used transcriptomics…
Transcriptome mapping of tomato fruit development and ripening (Nature Comms)
Plant Science Research WeeklyTomato (Solanum lycopersicum) is today the main model to study fleshy fruit development. Until now, most tomato growth and ripening studies are focused on a single tissue, the pericarp, and do not take into consideration the development of internal tissues. Shinozaki et al. provide an extensive spatiotemporal…
A NIN-LIKE PROTEIN mediates nitrate-induced control of root nodule symbiosis in Lotus japonicus
Plant Science Research WeeklyLegumes form root endosymbioses with Rhizobium bacteria in a special structure called nodule. In this symbiotic relationship, on one hand the plant provides the microbe with sugars and in exchange it receives fixed atmospheric nitrogen, the main limiting element for plant growth. Nevertheless, when nitrogen…
