https://doi.org/10.1105/tpc.18.00978 Schubert et al. identified a transcription factor that regulates ovule development in tomato. By Ramona Schubert and Bettina Hause Leibniz Institute of Plant Biochemistry, D06120 Halle/Salle, Germany Background: The survival of most plant species depends on proper flower development, successful fertilization, fruit and seed set to obtain the next generation. These processes demand specific […]
https://doi.org/10.1105/tpc.18.00961 Yi et al. describe a high-temporal-resolution transcriptome landscape of early maize seed development. By Fei Yi, Wei Gu, and Jinsheng Lai, State Key Laboratory of Agrobiotechnology and National Maize Improvement Center, Department of Plant Genetics and Breeding, China Agricultural University, Beijing, 100193, P. R. China Background: Maize seed is an important source of food, […]
Gao et al. identified a key protein phosphatase regulator of brassinosteroid signalling that modulates grain length and plant architecture. https://doi.org/10.1105/tpc.18.00836 By Ji Huang, State Key Laboratory of Crop Genetics and Germplasm Enhancement, College of Agriculture, Nanjing Agricultural University, Nanjing 210095, China Background: Brassinosteroids (BRs) are important plant hormones that play essential roles in plant growth […]
Zhang et al. identified intronic branch points and lariat RNAs in four plant species. By Binglian Zheng, Fudan University, China. Background: Most genes contain exons and introns; when genes are transcribed into precursor mRNAs, the introns must be removed and exons ligated to form mature mRNAs for translation into proteins. The removal of introns requires: […]
https://doi.org/10.1105/tpc.18.00663 Mikulski et al. find that the PWO chromatin regulator interacts with a structural component of the nuclear periphery. By Pawel Mikulski, Cell and Developmental Biology, John Innes Centre, Norwich, UK Background: DNA is wrapped around histone proteins forming a structure called chromatin. The cell nucleus contains regions of chromatin that are either active or […]
Zhao et al. identify a key regulator of fruit length variation in cucumber. Plant Cell https://doi.org/10.1105/tpc.18.00905 By Jianyu Zhao, China Agricultural University/University of Wisconsin-Madison; Li Jiang, China Agricultural University/Nanjing Agricultural University; Gen Che, China Agricultural University Xiaolan Zhang, China Agricultural University Background: Cucumber is one of the top 5 vegetable crops throughout the world, and […]
By Tessa Moses, The Institute of Quantitative Biology, Biochemistry and Biotechnology (IQB3), The King’s Buildings, University of Edinburgh, Edinburgh EH9 3FF, United Kingdom Photosynthesis is the process in which solar energy is used to fix atmospheric carbon dioxide (CO2) to chemical energy in phototrophs. Oxygenic photosynthesis is the principle producer of oxygen (O2) and organic […]
Okekeogbu et al. compare the glycomes and proteomes of the Golgi in grasses and dicots, finding that the differences in cell wall architecture are not reflected in differences between polysaccharides produced in the Golgi. Plant Cell https://doi.org/10.1105/tpc.18.00755 Background: Grasses and other commelinid species have a type of primary cell wall distinct from those of all […]
Baldrich et al. identified membrane vesicles with tiny RNAs The Plant Cell (2019). https://doi.org/10.1105/tpc.18.00872 By Roger Innes Background: All cells are defined by an outer membrane, which is made up of a lipid bilayer. Most cells shed small bubbles of membrane called extracellular vesicles (EVs). While EVs were once thought to simply be a trash […]
