Decaestecker and Buono et al. develop a system for tissue-specific gene knockout to enable phenotypic analysis of context-specific gene function. Plant Cell https://doi.org/10.1105/tpc.19.00454 By Ward Decaestecker, Rafael Andrade Buono, Moritz Nowack and Thomas Jacobs Background: As plant molecular…

Yu et al. study the function of FY in alternative polyadenylation. The Plant Cell (2019) https://doi.org/10.1105/tpc.18.00545 Zhibo Yu, Juncheng Lin, Qingshun Quinn Li Background: Polyadenylation of eukaryotic messenger RNAs (mRNAs) involves the addition of a ‘tail’ of dozens to hundreds of…

Schreier et al. uncover the surprising role played by the glucan phosphatase family member, LIKE SEX4 1, as a protein scaffold on the starch granule surface that binds β-amylases. Plant Cell https://doi.org/10.1105/tpc.19.00089. By Tina B. Schreier1,2 and Samuel C. Zeeman1 1 Institute of Molecular…

Plants have evolved to adapt to varied environmental niches. The ability to produce specialized metabolites is one of the evolved characteristics which help plants to thrive through varied biotic and abiotic conditions. Plant-associated microbes are always known to have a drastic impact on plant growth…

Calcium and chloroplasts are both at the heart of the signal transduction during environmental stress. Teardo et al. studied whether the chloroplast-localized mitochondrial calcium uniporter has a role in stress signaling. The group identified 6 homologs of mitochondrial calcium uniporter (MCU) in Arabidopsis,…

Wang et al. examine single-copy, conserved genes of unknown function, with OPENER as proof of concept. Plant Cell https://doi.org/10.1105/tpc.19.00033    By Wei Wang and Totte Niittylä, Umeå Plant Science Centre, Sweden  Background: Thale cress or Arabidopsis thaliana was the first sequenced…

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…

Dong et al. investigate cotyledon-specific light-regulated gene expression in Arabidopsis. The Plant Cell (2019). https://doi.org/10.1105/tpc.18.00803  By J. Dong, N. Sun, J. Yang, Z. Deng, J. Lan, G. Qin, H. He, X. W. Deng, V. F. Irish, H. Chen, and N. Wei Background: When germinating in darkness…
