Structure of Methylthioalkylmalate Synthase

Kumar et al. uncover the molecular basis for the diversification of the agriculturally important methionine-derived glucosinolates in plants. Plant Cell https://doi.org/10.1105/tpc.19.00046 Background: The chemical diversity of specialized metabolites in plants helps them to better adapt and survive in a variety of environments. Glucosinolates are amino-acid derived molecules primarily found in plants of the order Brassicales, […]

A Reversible Switch for Algal Photosynthesis

Roth et al. investigate how a green alga turns photosynthesis off and on when glucose is added and then removed from the culture medium. Plant Cell https://doi.org/10.1105/tpc.18.00742 By Melissa Roth and Krishna Niyogi, University of California-Berkeley Background: Photosynthesis is the life-sustaining process that plants and algae use to convert sunlight into the chemical energy that […]

HvCMF7 – a Key Switch of Chloroplast Differentiation in Barley

Li et al. identify the gene underlying the long-studied variegated albostrians mutant of barley. Plant Cell https://doi.org/10.1105/tpc.19.00132 By Mingjiu Li, Leibniz Institute of Plant Genetics and Crop Plant Research (IPK), Germany Background: Chloroplasts are the site of photosynthesis, which provides the energy basis of life for most organisms on earth. Chloroplast development requires the concerted […]

Autophagy regulates lipid biosynthesis and turnover

Fan et al. explore the roles of autophagy in Arabidopsis lipid metabolism. Plant Cell https://doi.org/10.1105/tpc.19.00170 By Jilian Fan, Linhui Yu and Changcheng Xu Biology Department, Brookhaven National Laboratory Background: Autophagy is a self-eating process during which cytoplasmic materials including macromolecules and organelles are delivered to vacuoles (yeast and plants) or lysosomes (mammals) for degradation. This […]
