Improved Pod Shattering and Controlled Seed Release Properties
- Technology Benefits
- Faster, more efficient seed harvesting will result from controlling seed-pod shattering. The technology has advantage both for direct seed products such as oilseeds, and for seeds to be used for propagation.
- Detailed Technology Description
- A scientist at UC San Diego has discovered that blocking expression of certain floral organ genes prevents the normal senescence of replum cells required for pod valve release and seed dispersal. Plants bearing this transgene construct do not release their otherwise normal, mature seeds without external applied mechanical effort. Thus, complete control of shattering in the field is achieved. Since premature seed dispersal can lead to serious losses of yield, it would be beneficial for producers of agricultural seed crops to gain control of the process using this technology.

Title: Control of fruit dehiscence in Arabidopsis by indehiscent1 genes
Usefulness: Control of fruit dehiscence in Arabidopsis by indehiscent1 genes
Summary: The polynucleotides of the invention provide a means of modulating fruit dehiscence which is useful for increased production of crops such as oil seed rape. The IND1 sequences can be used to prepare expression cassettes useful in a number of techniques, including inhibiting or suppressing expression.

State Of Development
Studies have focused primarily on recently characterized Arabidopsis genes that are strongly expressed in the valve/replum boundary and INDY1, a gene that is involved in fruiting body size. Mutant alleles of these genes have recently been characterized and newly created transgenic plants show a complete lack of replum structures, thus assuring that the valves can not come apart and disperse seeds.

- *Abstract
-
In many agricultural seed products—such as oilseed crops, grains, and legumes, as well as seed for planting—the premature release of seeds prior to harvest results in serious losses. Prior to this invention, visual examination of the crops and other agricultural techniques, such as determination of moisture content, have been the primary means to indicate timing of the seed harvest. This invention uses antisense genetic manipulation to achieve rational control of the natural regulatory mechanism of seed release.
