Analysis of the phytochrome gene family in Ceratodon purpureus by gene targeting reveals the primary phytochrome responsible for photo- and polarotropism.

abstract：:De-etiolation involves a number of phenotypic changes as the plants shift from a dark-grown (etiolated) to a light-grown (de-etiolated) morphology. Whilst these light-induced, morphological changes are thought to be mediated by plant hormones, the precise mechanism/s are not yet fully understood. Here we provide furth...
