Research Project: MOLECULAR ANALYSIS OF DEVELOPMENT TO IMPROVE COTTON FIBER Project Number: 6435-21000-016-00
Project Type: Appropriated

Start Date: Oct 01, 2010
End Date: May 28, 2013

Objective 1: To characterize spatial, temporal, and/or genotypic variation in cotton fiber gene expression and the mechanisms leading to this variation to identify strategies for producing cotton fiber with enhanced or novel properties. Objective 2: Determine the consequences of environmental factors on cotton fiber development and develop tools to mitigate these effects.

Determine global patterns of genetic differences and gene expression in genotypes that differ in fiber properties. Determine global patterns of gene expression in cotton ovule cultures that are induced to express secondary cell wall CesA genes prematurely. Validate transcription factor candidates by functional genomic approaches in model systems and cotton. Compare the gene expression profiles from controls and cotton plants undergoing heat and/or drought stresses. Determine the effects of heat units on fiber strength and expression of genes specifically involved in the transition period. Evaluate the effects of drought on the fiber quality in a group of varieties (germplasm lines).
