Review: Long distance signlaing in plant stress response (COPB)

To compensate for their lack of a nervous system, vascular plants have developed complex mechanisms to connect their organs and coordinate stress. Many different types of molecules are involved in long-distance signaling and must be integrated to maintain homeostasis. In this review, Takahashi and Shinozaki explore current knowledge of plant molecules including small proteins, peptides, RNAs, metabolites, and second messengers and their important roles in plant defense and adaptation. The authors place a special emphasis on mobile peptides and their recently discovered as roles as mobile mediators that complement the regulatory functions of phytohormones.
