Thousands of nuclear-encoded proteins are transported into chloroplasts through the TOC–TIC translocon that spans the chloroplast envelope membranes. A motor complex pulls the translocated proteins out of the TOC–TIC complex into the chloroplast stroma by hydrolyzing ATP. The Orf2971–FtsHi complex has been suggested to serve as the ATP-hydrolyzing motor in Chlamydomonas reinhardtii, but little is known

AtWRKY1 at the intersection of plant development and defense: The cost of coping with adversity Mol. Plant (IF 17.1) Pub Date : 2024-09-02 Andreas M. Fischer
The life cycle of many plants including our most important crops is short, with weeks to months between germination and death. Monocarpic plants flower only once, with seed/grain filling dependent on nutrient remobilization from senescing parental plants. A mature crop stand such as a harvest-ready wheat field is the result of mass suicide, with only the seeds/grains as living entities.
