Abstract

The phytochrome family (phyA to phyE in Arabidopsis) perceive regulatory light signals and control all aspects of plant development. Through analysis of mutants null for phyA, phyB, phyD (and the corresponding multiple mutants) it is clear that different phys perform different functions and that there is redundancy within the family. Phytochrome B and D play an important role in plant responses to red:far-red ratio, whereas phyA is important in seedling establishment and, along with other photoreceptors, in daylength perception. The functions of phyC and phyE have remained unknown, and mutations at PHYC or PHYE have not been identified by conventional screens. The objective of this research is to use the Arabidopsis mutant gne7, which carries a deletion spanning the PHYC gene, to generate a monogenic phyC mutant and then to define the functions of this low abundance photoreceptor.
