An Unexpected Role of a Phosphatase-like Protein in Starch Degradation

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…

A chloroplast-localized mitochondrial calcium uniporter transduces osmotic stress in Arabidopsis (Nature Plants)

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,…

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…
