Research Project: Mechanisms for Creating Non-Invasive Nursery Crops

Location: Floral and Nursery Plants Research Unit

Project Number: 8020-21000-061-01
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2009
End Date: Jul 31, 2014

Objective:
The primary objective of this work is to develop techniques and methods that will lead to sterile or highly infertile cultivars of invasive or potentially invasive nursery crops.

Approach:
The general approach is to use use biotechnology or genetic engineering to create seedless plants or to develop methods that will lead to the creation of seedless plants. One area of study will be to test gene suppression using the AGAMOUS gene and dsRNA-RNAi. The AGAMOUS gene is a floral homeotic gene that, when suppressed or mutated, can result in flowers that have petals in place of pistils and stamens, and are therefore sterile. The second area of study will be to create transgenic plants using several different gene constructs that may induce male and/or female sterility.
