Abstract
Heat shock proteins (HSPs) are the key components of plants’ adaptive mechanism to maintain protein homeostasis. HSPs play critical roles not only in response to unfavorable environmental conditions, but also during normal plant growth and development. Compared with yeast and animals, plants’ HSP-encoding genes have expanded into a large gene family, likely because of their sessile lifestyle. These genes have divergent expression patterns in various plant organs, and respond at various levels to heat treatment. While the genetic control of plant HSP genes by upstream heat shock factors has been well studied, the epigenetic regulation of these stress-responsive genes has emerged as a critical pathway implicated in the plant response to environmental changes. In this chapter, we summarize the progress regarding the epigenetic regulation of plant HSP gene expression. The common and disparate epigenetic pathways and factors in the heat response in plants and other organisms are also discussed.
