I am a tomato breeder working, currently focused on transfer of resistances to biotic stresses, to reduce damage/loss of crop, while reducing use of fungicides, copper sprays, and pesticides. This allies with the development of IPM, of sustainable agriculture and of use of biological controls.

Interests

Tomato and onion breeding and genomics

Disease and insect resistance

Intellectual property

Recent Research

My research projects concern the genetic control of novel traits, chiefly derived from wild tomato species, and their transfer to cultivated tomato. Primary research focuses on issues that limit cultivar quality and production, such as critical diseases as well as insect pests and the virus they transmit.

Resistance to fungal, oomycete, and bacterial diseases. One project underway focuses on bacterial and fungal diseases critical to the New York and the northeast and mid-Atlantic states. The oomycete disease late blight (caused by Phytophthora infestans), and fungal diseases early blight (caused by Alternaria tomatophila), and Septoria leaf spot (caused by Septoria lycopersici), can cause defoliation, plant collapse, and loss of yield and fruit quality in temperate tomato growing regions. Two of the most critical bacterial disease are bacterial spot (caused by Xanthomonas vesicatoria, X. euvesicatoria, X.s gardneri, and X. perforans) and bacterial speck (Pseudomonas syringae pv)

To reduce the need for fungicides and copper sprays traditional used to control the three fungal/oomycete diseases required the combined transfer of resistances to each of these diseases. Transfer of genetic resistances to late blight, early blight, and Septoria leaf spot created tomato lines now being used by seed companies. Commercial hybrids with combined blight resistances reduced risk of loss due to these diseases, allowing up to 75% reduction in fungicide use in conventional tomato, and reductions of copper sprays in organic tomato, creating a more sustainable system for control of foliar fungal disease in tomato production. The remaining weakness in the blight resistant lines created was incomplete resistance to early blight, particularly in foliage. This has been recently rectified by discovery and transfer of an additional QTL providing early blight control specifically to foliage.

As the work adding blight resistances was nearing completion, transfer of resistances to bacterial diseases was initiated. Lines nearing completion have resistances to bacterial spot, or both bacterial spot and bacterial speck, in addition to the fungal disease resistance of the initial lines. The resulting new bacterial/fungal/oomycete resistant lines will further reduce need for both fungal and copper sprays, reducing costs of production, while protecting against loss of crop or crop quality.

Control of insects and insect transmitted viral pathogens. The other project underway focuses on a range of insect pests, and insect transmitted virus, which are serious in southern US and tropical/semitropical regions and are moving northward due to climate change. The insect/virus control project has examined the genetic control of acylsugar-mediated multiple insect resistance in tomato, created a series of sister lines of tomato that produce different levels or different chemical forms of the acylsugars. I interact with entomologists/pant pathologists at universities or research centers in the US and abroad to determine the range of insect species controlled by the acylsugars produced by these tomato lines, the efficiency of the control, and whether controlling the insect pest significantly reduces likelihood that plants are infected by insect-transmitted virus. We are also working to refine the horticultural type of the acylsugar lines with the best insect/virus control, so that the lines can be readily used by seed companies interested in utilizing this trait in new hybrids. Use of hybrids with this strong insect/virus control should significantly reduce the need for, and use of, chemical pesticides in the US and similar countries. It could also materially benefit developing countries, where cost of pesticide control can be prohibitive and losses due to insect pests/viral diseases can be very high.

Outreach and Extension Focus

The extension and outreach aspect of my work are largely associated with my research in tomato breeding. I interact with global seed companies and an international research center overseas, international tomato processing companies, tomato growers and processor groups in other states, and organic tomato growers in NYS.

Each year I make several presentations to grower or industry groups. Some work for the bacterial/fungal disease resistance project is done with cooperation of extension faculty/staff, including trials on host grower farms. Due to these presentations and interaction with host growers, I have interactions with tomato conventional and organic growers and I respond to periodic requests or questions. I usually make annual presentations to extension personnel during in service sessions, I also make 2 or 3 presentations to seed company representatives at organized Field Days.

Since seed companies are using lines we have released, as well as molecular markers and biochemical techniques developed, I also interact with seed company representatives to assist them in using the materials, and training company staff in new techniques.

As a cooperator on an inter-university projects on acylsugar mediated insect resistance, I am assisting in outreach, providing basic researchers information regarding tomato cultivars, traits and production that help refine their projects, and give guidance regarding how basic information generated by the project could be utilized for applied benefit.
