Making longer rice grains, the brassinosteroid way

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…

Identification of branch points and lariat RNAs during splicing in plants

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…

The Surprisingly Similar Glycomes of Maize and Arabidopsis Golgi

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…

Plant Cells Shed Membrane-Bound Bubbles that Are Packed with Tiny RNA Molecules

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…

Getting to Know Each Cell in an Arabidopsis Root

Jean-Baptiste et al. use single-cell transcriptomic profiling to map developmental trajectories and assess cell-type specific changes during heat shock, demonstrating that single-cell transcriptomics holds promise for studying plant development and plant physiology at unprecedented resolution. Plant…
