Transcriptomics and trans-organellar complementation reveal a limited signaling capacity of 12-cis-oxo-phytodienoic acid in wounded Arabidopsis

The paper investigates OPDA signaling in Arabidopsis by comparing transcriptomes of mutants and applying OPDA externally, finding limited signaling capacity and compartmentalization of endogenous OPDA.

Heat stress induces a developmental shift from type-V to type-IV trichome dependent on jasmonate signaling in tomato

Heat stress induces a switch from type-V to type-IV trichomes in tomato, dependent on jasmonate signaling, with increased acylsugar production.

Auxin-dependent acceleration of cell division rates regulates root growth at elevated temperature

This study shows that elevated temperature promotes primary root growth in Arabidopsis thaliana by accelerating cell division rates through auxin-mediated signaling, distinct from shoot thermomorphogenesis.

PSK signaling controls ABA homeostasis and signaling genes and maintains shoot growth under osmotic stress

This study shows that PSK receptor signaling regulates ABA synthesis and signaling genes, promotes ABA accumulation in shoots under osmotic stress, and maintains growth and photosynthetic efficiency.

Jasmonate biosynthesis arising from altered cell walls is prompted by turgor-driven mechanical compression and guides root hydrotropism

The paper shows that mechanical compression from enlarged cortex cells increases JA-Ile biosynthesis, which directs root hydrotropism.

Shoot-to-root translocation of the jasmonate precursor 12-oxo-phytodienoic acid (OPDA) coordinates plant growth responses following tissue damage

This study identifies OPDA as a mobile jasmonate precursor that translocates from damaged shoots to roots, coordinating growth responses in Arabidopsis.
