Abstract
An isolated nucleic acid molecule is provided comprising a nucleotide sequence which encodes a glutamine:fructose-6-phosphate amidotransferase from E. coli which is particularly suitable for expression in cotton plant cells. The invention also relates to plant cells or plants, in particular to cotton plant cells or cotton plants which produce an increased amount of positively charged polysaccharides in their cell walls. Furthermore methods and means are provided to increase the content of positively charged polysaccharides in the cell walls of cotton cells, in particular in cotton fibers. Fibers obtained from such cotton plants have an altered chemical reactivity which can be used to attach reactive dyes or other textile finish reagents to these fibers.
