Summary

Plants, unlike animals, are not mobile, and therefore unable to avoid stressful environmental conditions. As a consequence, plants have developed a wide variety of protective and defensive mechanisms in order to survive adverse conditions. Abiotic stresses, such as low temperature, high salinity, drought, or osmotic stress, are common challenges to plant survival, and negatively affect plant growth and development. From the point of view of molecular biology and biochemistry, stress signals are, in most cases, perceived by cellular receptors sitting on the cell membranes. These receptors transmit their information through multiple intermediate components in the signal transduction pathways, in order to finally activate the effector proteins, which are involved in executing physiological changes inside plant cells. However, most abiotic stress signalings, such as low-temperature stress signaling, are not linear, but are interconnected with each other. A myriad of molecules and proteins, including ions, lipids, protein kinases, and transcription factors, participate in the stress signal transduction networks. Such complex signaling networks pose a huge challenge to scientists attempting to understand the molecular and biochemical mechanisms plants employ to survive life-threatening conditions. Nevertheless, with the development of a number of advanced technologies, such as DNA microarray for global mRNA profiling, LC/MS/MS mass spectrometry for global proteomic profiling, and an abundance of new functional genomics tools, significant progress has been made in illuminating the mechanisms of plant abiotic stress responses. This chapter summarizes the most recent discoveries about the components involved in plant abiotic stress, with an emphasis on cold stress responses, and focuses on elucidating the functions of these components and their contribution to cold signaling.
