Transgenic Plants Having Improved Pod Shattering and Controlled Seed Release Properties
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.
A scientist at UCSD has discovered that overexpression 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: Seed plants characterized by delayed seed dispersal
Usefulness: Seed plants characterized by delayed seed dispersal
Summary: USE The products and methods can be used for producing plants which are characterised by delayed seed dispersal, including members of the Brassicaceae, such as rapeseed, and members of the Fabaceae, such as soybeans, peas, lentils and beans.
Novelty: Use of agamous-like nucleic acids useful for the production of transgenic seed plants in which dehiscence is modified resulting in delayed seed dispersal
