Project Number: 5440-21220-027-11
Project Type: Specific Cooperative Agreement

Start Date: Jul 20, 2004
End Date: Jul 19, 2009

Objective:
The objective of this cooperative research project is to determine the effect of transgenes from sorghum on the fitness of shattercane × sorghum hybrids.

Approach:
Sorghum with transgenes causing it to have purported increased digestibility due to over-expression of thioredoxin will be crossed to shattercane in the greenhouse using standard emasculation procedures. Hybrid progeny with and without transgenes will be evaluated to determine presence of the transgenes using DNA hybridization blots. The F1 hybrids and subsequent generations will be compared for fitness parameters including seed production, seed longevity and viability, and growth rate with and without interplant competition.
