Project Number: 6435-21440-002-00
Project Type: Appropriated

Start Date: Jul 26, 2001
End Date: Jun 30, 2006

Objective:
Characterize the structure and function of genes and their associated promoters that are required for cotton fiber development.

Approach:
Conduct functional analyses of cotton fiber genes previously isolated by differential display and other methods; Use rapid methods for evaluating the efficacy/strength of cotton promoters without the need to construct transgenic cotton plants; Measure minimal sizes of cis elements that specify the temporal/spatial localization patterns and hormonal induction of cotton fiber gene expression; Determine if promoter structures are different for selected genes in G. hirsutum, G. barbadense, and other Gossypium species; Evaluate how long gene expression proceeds during fiber development and whether there are any very late genes expressed in cotton fiber.
