An RNA splicing factor functions in plant seed development

Bai et al. show that an RNA splicing factor promotes normal cell differentiation and stops excessive cell proliferation in the corn kernel. Plant Cell https://doi.org/10.1105/tpc.18.00754   By Fang Baia, Jacob Corllb, and A. Mark Settlesa aHorticultural Sciences Department and Plant Molecular and Cellular Biology Program, University of Florida, Gainesville, Florida, 32611, USA bDepartment of Biological […]

Pseudogenes in Plants: Their Associations with Long Noncoding RNAs and MicroRNAs

Xie et al. applied a multifaceted approach to study plant pseudogenes, combining RNA-seq, comparative genomics, and molecular biology. They conclude that rapid rewiring of psuedogene transcriptional regulatory regions is a major mechanism driving the origin of novel regulatory modules. Plant Cell https://doi.org/10.1105/tpc.18.00601 Background: Genomes contain a range of elements including not only genes, but also […]

Transcription factors regulate wood formation

Chen et al. construct a transcriptional regulatory network governing wood formation. Plant Cell http://doi.org/10.1105/tpc.18.00620   By Hao Chen, Department of Plant and Microbial Biology, North Carolina State University Jack Wang, Forest Biotechnology Group, Department of Forestry and Environmental Resources, North Carolina State University Vincent L. Chiang, Forest Biotechnology Group, Department of Forestry and Environmental Resources, […]

Daily Rhythms of Leaf Hydraulics: a Matter of the Clock and Phosphorylation

Prado et al. uncover a mechanism that tunes the hydraulics of leaf tissues to synchronize water supply with day and night cycles, thereby optimizing plant growth. Plant Cell https://doi.org/10.1105/tpc.18.00804    Background: Plants must cope with daily fluctuations in temperature, light, and humidity. Plants continuously adjust their water status by regulating transpiration through stomatal pores present […]

Phloem Companion Cell-Specific Transcriptomics and Epigenomics

By conducting phloem companion cell-specific transcriptomic and epigenomic analyses, You et al. identify MRF1, a novel regulator of flowering. Plant Cell https://doi.org/10.1105/tpc.17.00714 By Yuan You1,2 and Markus Schmid1,3 1 Max Planck Institute for Developmental Biology, Department of Molecular Biology, Max-Planck-Ring 9, 72076 Tübingen, Germany. 2 Center for Plant Molecular Biology (ZMBP), Department of General Genetics, University […]

The Epigenetics of Leaf Senescence

Liu et al. explore the mechanism underlying the epigenetic reprograming of senescence-associated gene expression during leaf senescence. Plant Cell https://doi.org/10.1105/tpc.18.00693    By Peng Liu, Jing Bo Jin, and Xiaofeng Cao, Chinese Academy of Sciences, Beijing, China. Background: Leaf senescence is the highly ordered final stage of leaf development. During leaf senescence, chlorophylls, nucleic acids, lipids, […]

SME1 shapes plant development and freezing tolerance

Huertas et al. show that SME1 modulates spliceosome activity to shape plant development and tolerance to freezing temperatures. Plant Cell https://doi.org/10.1105/tpc.18.00689   By Raúl Huertas, Noble Research Institute, Admore, Oklahoma, USA. Rafael Catalá, Centro de Investigaciones Biológicas-CSIC, Madrid, Spain. Julio Salinas, Centro de Investigaciones Biológicas-CSIC, Madrid, Spain.  Background: Tight regulation of gene expression is essential […]

Impact of Biolistic Transformation on the Genome

Liu et al. show that biolistic transformation can cause extensive damage and rearrangements, including deletions, duplications, chromosome fusions, and copy number variations. Plant Cell https://doi.org/10.1105/tpc.18.00613   By Jianing Liu and R. Kelly Dawe, Department of Genetics, University of Georgia.  Background: Agrobacterium-mediated gene transfer and biolistic transformation are the two most widely used methods for plant […]

How Stress Experience Strengthens a Tree

Georgii et al. uncover transcriptomic memory in poplar trees after recovery from drought-heat stress, which changes with stress frequency and intensity and involves a complex interplay of common and tissue-specific factors. Plant Cell https://doi.org/10.1105/tpc.18.00431    By Elisabeth Georgii and Jörg-Peter Schnitzler Helmholtz Zentrum München, German Research Center for Environmental Health, Germany   Background:  Plants, particularly […]
