COTTON FIBER TRANSCRIPTIONAL FACTORS.

摘要

Novel DNA constructs are provided which may be used as molecular probes or inserted into a plant host to provide for modification of transcription of a DNA sequence of interest during various stages of cotton fiber development. The DNA constructs comprise a cotton fiber transcriptional initiation regulatory region associated with a gene which is expressed in cotton fiber. Also provided is novel cotton having a cotton fiber which has a natural color introduced by the expression in the cotton fiber cell, using such a construct, of pigment synthesis genes. Cotton fiber cells having color produced by genetic engineering and cotton cells comprising melanin and indigo pigments are included.
