The role of phytochrome in stress tolerance.

摘要: Phytochromes, which absorb red (R)/far (FR) light, are the most characterized photoreceptors in plants and have been shown to mediate a wide range of molecular biochemical responses. These include responses biotic abiotic stresses, currently major challenge plant research. Extensive studies exploring basis by phytochromes modulate stresses such as drought, high low temperatures or herbivory, among other, carried out many species. In particular, considerable efforts also made unravel involvement salt stress For example, involving phytochrome now understood following using R/FR light ratio treatments, well isolation characterization photomorphogenic mutants transgenic plants, revealed an important role on tolerance mechanisms. this chapter, we will explore pieces information available make clear perspectives focused photomorphogenesis manipulation scope agriculture.
