Keel petal incision: a simple and efficient method for genetic crossing in Medicago truncatula.

ABSTRACT:

Background

Genetic crossing is an essential tool in both forward and reverse genetic approaches to understand the biological functions of genes. For Medicago truncatula (barrel medic) various crossing techniques have been used which differ in the methods used to dissect the female parent's unopened flower bud to remove immature anthers for prevention of self-pollination. Previously described methods including front, side or back incision methods may damage the flower bud, impeding successful fertilization and/or seed development because they may allow pollen to dislodge and floral organs to desiccate after crossing, all of which diminish the success rates of crossing.

Results

We report the keel petal incision method for genetic crossing in M. truncatula ecotype R108 and demo
