High-temporal-resolution Transcriptome Landscape of Early Maize Seed Development

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…

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…

Cell Wall Polymers: The Importance of Deacetylation

Many of the polysaccharides that make up the plant cell wall carry acetate side groups. Notably, the degree of such acetylation is not always the same—even within the same species, it changes over the course of development and is different between tissues. While the mechanism for adding acetyl groups…

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…

A growing reputation for FRUITFULL genes

The sub-functionalization and neo-functionalization of duplicated MADS-domain containing transcription factor coding genes has driven angiosperm evolution. These transcription factors control almost every facet of reproductive development in plants and are key breeding targets for crop yield improvement.…

How to pack chromatin in nuclear space? A plant-specific chromatin regulator associates with component of the nuclear periphery

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…

The Future is Now: Gene Expression Dynamics at Single Cell Resolution

For the past 10 years, a popular method to study global gene expression changes has been RNA sequencing of bulk tissues. However, an inherent limitation of this approach is the confounding of multiple cell types or multiple developmental stages. By contrast, new technologies enable transcriptional profiling…
