A Force-Generating Machine in the Plant's Power House: A Pulling AAA ATPase Motor Drives Protein Translocation into Chloroplasts

Most chloroplast proteins are encoded by the nuclear genome and synthesized on cytosolic ribosomes. N-terminal transit peptides serve as targeting sequences to direct precursors of chloroplast proteins to receptors on the chloroplast surface. These receptors are part of the translocase of the outer envelope,…

Inhibition of TOR, Nitrogen Assimilation, and Amino Acid Biosynthesis: Lessons from Chlamydomonas

To survive, organisms must sense their nutritional status (including nutrient availability and quality) and regulate their growth and metabolism accordingly. In plants, animals, and fungi, the Target of Rapamycin (TOR) kinase regulates metabolism, nutrient sensing, and growth (reviewed in Dobrenel et…

Sweet and Juicy: Identification and Origins of the Dry Alleles in Sorghum

Sorghum (Sorghum bicolor) is the fifth most important cereal crop globally and is considered to be the “camel among crops” due to its ability to flourish in low-nutrient soils and to withstand prolonged drought. Cultivated varieties are phenotypically and morphological diverse. Consequently, sorghum…

What Do YOU Want to Ask the Next Editor-in-Chief of The Plant Cell?

We have been charged by ASPB to conduct a search for the next Editor-in-Chief of The Plant Cell.  Back in March of this year, we began the search process by meeting as a group to discuss potential candidates for this important role.  We invited candidates and issued a call for nominations to…

Moonlighting Role of Plastidial NAD-MDH

Schreier et al. investigate the role of a plastid malate dehydrogenase in early chloroplast development. Plant Cell 30: 1745-1769 Background: Malate dehydrogenases (MDH) are enzymes that are widespread in prokaryotes and eukaryotes. MDH interconverts oxaloacetate and malate, using either NAD or…

Plant Systemic Immunity Comes Full Circle: A Positive Regulatory Loop for Defense Amplification

The plant immune system is effective in conferring resistance to various invading pathogens and pests. Membrane-localized pattern recognition receptors (PRRs) and intracellular nucleotide-binding domain, leucine-rich repeat proteins (NLRs) recognize pathogen-associated molecular patterns and pathogen…
