Quality of cotton fibre
Cotton fibre is the natural fibre most used by the textile industry. It has a unicellular structure which develops from epidermal cells of the seed integument. We currently have few molecular data that would enable a correlation to be made between gene expression and the technological quality of the fibres (length, strength, resistance to stretching...). It is now possible to identify which genes account for the different qualities of fibres in diverse mutants, varieties and species of cotton plant. For this, patterns of expression of cDNA (complementary DNA) and of Expressed Sequence Tags (ESTs) during cotton fibre development are investigated. This indicates which genes are involved in this agronomic trait and, in each case, identifies the favourable alleles. It will thus be possible to locate important genes whose expression determines in fine intrinsic fibre quality, and possibly to assign a biological function to these genes. The candidate genes thus identified are of agronomic interest and can be genetically tested in the analysis of Quantitative Trait Loci involved in the fibre technological quality. (Texte intégral)
