The mission of the D.C. Kiplinger Floriculture Crop Improvement Lab is to advance the science and practice of floriculture. Research focuses on improving floriculture crops for both producers and consumers using molecular, physiological and microbial approaches.
Microbe-containing products for enhancement of floriculture crops
We are utilizing the plant rhizosphere microbiome to identify microorganisms that may be beneficial to floriculture crops. These beneficial microbes may enhance plant health (act as biostimulant) by increasing root elongation, nutrient uptake, and stress tolerance.
There are an increasing number of biological products marketed as plant growth enhancers or biostimulants. One barrier identified by Greenhouse industry stakeholders to the use of biostimulants has been the lack of a single, non-bias resource that contains biostimulant products available for use on greenhouse floriculture crops. We have created an interface that is a compilation of products that (1) contain microorganism(s), (2) are advertised as biostimulants (i.e., enhance plant growth), and (3) can be used in a greenhouse and/or on flowering plants. This tool was developed with support from NIFA/USDA Specialty Crops Research Initiative. Please visit the Microbe-containing bioproducts page for more information and to access the resource specific for greenhouse floriculture crops.
Molecular and biochemical regulation of senescence in plants
The senescence or death of leaves, flowers and whole plants occurs naturally as part of the last stage of plant development, but it can also be accelerated by ethylene and environmental stress. We are interested in senescence because it reduces the postproduction quality and marketability of ornamental plants. Senescence is genetically controlled and we are using proteomic and genomic approaches to identify pathways involved in the initiation and execution of the senescence program in petals. Functional analysis of senescence associated genes is conducted using virus-induced gene silencing in Petunia.
