How Plants Adapt to Different Temperatures

Méndez-Vigo et al. explore how plants from different world regions adapt to different temperature conditions. Plant Cell https://doi.org/10.1105/tpc.18.00938.    By Belen Méndez-Vigo and Carlos Alonso-Blanco  Background:  Plants adapt to seasonal and yearly fluctuations in ambient temperature by altering multiple aspects of their development, such as growth and the time to initiate flowering. These modifications in […]

A Glucose Transporter Promotes Stomatal Conductance and Photosynthesis

Hai Wang et al. identify a regulator of stomatal movement and photosynthesis. Plant Cell https://doi.org/10.1105/tpc.18.00736 By Hai Wang, Biotechnology Research Institute, Chinese Academy of Agricultural Sciences Background: Fixation of atmospheric CO2 through photosynthesis is crucial for the survival of plants, and is also pivotal for meeting the ever-increasing food, feed and fuel demands of humans. […]

An RNA-chaperone-like Protein in Chloroplasts

Jiang et al. isolated a plastid-localized RNA-chaperone-like protein and investigated its function. Plant Cell https://doi.org/10.1105/tpc.18.00946.  By Jingjing Jiang, Xin Chai, Nikolay Manavski, and Wei Chi  Background: RNA folding, which underlies the formation of RNA structure, is important for the functions and regulation of RNAs in all living organisms. RNA chaperone proteins have evolved to assist […]

An Electron Shuttle for Lignin Biosynthesis

Guo et al. uncover a unique electron donor protein for syringyl lignin biosynthesis in Arabidopsis thaliana. The Plant Cell (2019). https://doi.org/10.1105/tpc.18.00778  By Chang-Jun Liu  Background: Plants use sugar from photosynthesis as a carbon and energy source for their growth and development. When sugar breaks down, it releases the stored energy needed to drive a variety […]

MYB21 in Tomato: No Seeds Without Me

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 […]

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 Breeding, China Agricultural University, Beijing, 100193, P. R. China Background: Maize seed is an important source of food, […]

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 University, Nanjing 210095, China Background: Brassinosteroids (BRs) are important plant hormones that play essential roles in plant growth […]

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 for translation into proteins. The removal of introns requires: […]

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 a structure called chromatin. The cell nucleus contains regions of chromatin that are either active or […]
