TL;DR: A SAL1-PAP retrograde pathway that can alter nuclear gene expression during HL and drought stress is proposed and it is shown that PAP is a primary in vivo substrate.

TL;DR: Results indicate that aox1a plants have a greatly altered stress response even when mitochondria or the mitochondrial electron transport chain are not the primary target of the stress and that AOX1a plays a broad role in determining the normal redox balance in the cell.

TL;DR: This work identifies a biological role for ANAC017 as an integral cellular component in mitochondrial retrograde signaling and a high-level transcriptional regulator that is necessary for H2O2-mediated primary stress responses in plants.

TL;DR: Results show that ABI4 plays a central role in mediating mitochondrial retrograde signals to induce the expression of AOX1a, and provide a molecular link between mitochondrial and chloroplast retrograde signaling, as ABI 4 has been previously shown to act downstream of at least two chloroplastic retrogrades signaling pathways.

TL;DR: Evidence is provided that the presence of P can affect Fe availability and in turn can influence the regulation of Fe-responsive genes.
