Research Project: Development of Cdna Microarrays for Gene Expression Research in Floricultural Crops

Location: Subtropical Insects and Horticulture Research

Project Number: 6618-22320-001-20
Project Type: Specific Cooperative Agreement

Start Date: May 01, 2010
End Date: Sep 30, 2014

Objective:
To continue research to identify differentially expressed genes in the ornamental plant Petunia, floricultural crops and, from this information, to develop promoters that regulate specific genes involved in floral senescence and plant nutrition. To use genetics/genomics research to enhance traits in floriculture crops that address consumer preferences, such as floral fragrance.

Approach:
Develop a coordinated research effort to isolate and sequence promoter elements in floricultural crops, to analyze expression of these genes using macro- or micro-array analysis, to identify genes with specific expression characteristics associated with tissue and physiological states, and to verify promoter function of specific genes using transgenic Petunia as the model.
