Description

<p>Higher plants respond to various types of environmental stresses to adapt against those stressful conditions.　They receive environmental information from roots and leaves and then integrate the information as a whole because the environmental conditions of underground and aerial parts are very different.　To adapt to complex environmental conditions at whole plant level, long-distance signaling is important for plants for their survival.　Recent studies have elucidated that various mobile molecules transmit the extracellular stimuli from sensing tissues to target organs.　These mobile molecules include hydroxy pressure, calcium currents, peptides, phytohormones and so on.　These indicate that the plants have unique and complex mechanisms for connecting various organs precisely although they do not have nervous system.　In this review, we focused to summarize current knowledge of molecules in long distance signaling for abiotic stress responses, mainly drought stress response.</p>
