Technology Development Workshop

March 5-6, Celaya, Mexico

Background

• First workshop between Mexico and Canada to discuss current/future collaborative research in beans

• INIFAP, AAFC, Mexican and Canadian Universities

Background

• Topics: genetic improvement, biotechnology, functional foods/ nutraceuticals

• INIFAP project list reviewed

• Focus: science, collaboration, deliverables

• Discussion on next steps

Proposed Projects

1. Development of bean cultivars tolerant to biotic and abiotic stresses

2. Functional genomics and molecular marker development for bean breeding

3. Development of slow-darkening varieties and varieties with reduced cooking time

4. Development of functional foods from beans to target diabetes prevention

1. Development of bean cultivars tolerant to biotic and abiotic stresses

Background: Global climate change (prolonged droughts, high temperatures, combinations of both) Occurrence of devastating insect plagues such as white fly and leaf hopper High incidence of pathogens that cause root-rot (Fusarium spp and Rhizoctonia solani), and common

bacterial blight (CBB) (Xanthomonas campestris) will increase over the short term in bean production areas.

Key words: genetic diversity, tolerance to adverse factors, sources of resistance . Benefits: Development of main market class cultivars that are resistant to biotic and abiotic stresses will reduce production risks and contribute to consistency in yield and quality; traditional and upright architecture

Actions:Short term (2007): Exchange of lists and sources of resistance. Technical exchange visitsMedium term (2008): Common nurseries: a) black bean varieties tolerant to common blight; b) pinto bean varieties with drought toleranceLong term: registration and multiplication of new varieties with drought and disease resistance

Risks / Weaknesses: The identified sources of resistance in Mexico may not function in Canada and vice versa

Conclusions: Collaboration between scientists from both countries will enable the development of new cultivars incorporating multiple resistances

Collaborators: INIFAP, AAFC, University of Saskatchewan and University of Guelph, (with IICA support)

2. Functional genomics and molecular marker development for bean breedingBackground:

Breeders in both countries have used a limited set of molecular markers linked to CBB resistance with varying degrees of success. Development of gene-based markers would greatly facilitate marker-assisted selection, increase the efficiency of breeding programs and lead to the development of improved varieties.

Key Words: marker-assisted selection, genetic improvement

Actions: short term: CBB markers and protocols currently in use will be shared

Identify current populations that could be grown in different regions to phenotype for disease and stress reactions Link up with US researchers working on CBB and stress tolerance

Medium term: Develop and utilize recombinant populations specifically to map genes of interest Develop molecular markers linked to drought and CBB resistance to select for resistant linesDevelopment of transformation technology to confirm the function of specific genes for traits of interest

Long term: Develop QTL and gene-based markers for other characteristics related to bean quality (slow darkening, phytochemicals)

Benefits: molecular markers linked to genes with specific functions will improve the efficiency of cultivar development

Risks / Weaknesses: Lack of densely populated gene maps; markers may not be universally applicable

Conclusions: The application of biotechnology will enable development of new varieties, including those with the needed genetic resistances.

Collaborators: INIFAP, AAFC, University of Saskatchewan and University of Guelph

3. Development of slow-darkening varieties and varieties with reduced cooking time

Background: Slow-darkening extends shelf-life of dry beans Consumers demand fast-cooking varieties Canadian and Mexican consumer interest in light-coloured beans with these characteristics Longer cooking time has been associated with decreased nutrition Canners would benefit from quicker, more uniform cooking varieties

Key Words: shelf-life, seed coat impermeability, hard seeds

Benefits: Improved market quality and greater benefits to the consumer and canners; therefore, all players in the value chain benefit

Actions: Short Term: Exchange of slow-darkening genetic materials particularly of light-coloured beansMedium Term: Development of RIL populations from contrasting parental phenotypes (RILs) Longer Term: Identify specific seed coat compounds linked to slow-darkening trait and the effect of the interaction of light

Risks / Weaknesses: Slow-darkening trait is not easily transferred among market classes; wholesalers may mix slow-darkening bean varieties with regular bean varieties

Conclusions: Meeting consumer demands is necessary and will benefit producers

Collaborators: INIFAP, AAFC, University of Saskatchewan and University of Guelph

4 . Development of functional foods from beans to target diabetes preventionBackground:

Diabetes is probably the most important disease in our society due to the increasing number of people affected and the economic burden on the healthcare system.

Bean phytochemicals have demonstrated beneficial effects in diabetes and colon cancer in rats Two cultivars demonstrated more pronounced effect (Pinto Zapata and Black 8025) which vary in

phyto-chemical concentration

Key Words: functional foods, diabetes, metabolic disorders

Benefits: Development of new products that may improve health and wellness

Actions: Short Term: Implementation of methods developed in Canada to analyze bean phytochemicas in serumMedium Term: 1) Epidemiological study relating bean consumption and prevalence of metabolic disorders such as diabetes; 2) Gene expression resulting in bean phytochemical synthesis especially related to diabetes Longer Term: Clinical studies involving obese children and pre-diabetic young adults in Mexico using dietary intervention with existing and new FF bean products (PZ, N8025)

Risks / Weaknesses: Regional consumer preference may not be for these selected beans; transfer of results from rat model may not apply to human clinical trials

Conclusions: Consumption of beans and bean products may prevent diabetes and obesity among the target population

Collaborators: INIFAP, AAFC, SAGARPA, University of Guelph, University of Tor onto,Diabetes Association of LA, IICA

Next Steps: Research

Short-term Deliverables:• Exchange of germplasm (disease and drought

resistance, quality traits)• Scientist visits, student internships• Exchange of knowledge on molecular markers,

specific populations, methods/protocols• Transfer of protocols/methods for analyzing

phytochemicals in blood• Two joint meetings in next year (proposed: July

& October, CMP?)

Next Steps: Administrative Support

• Complete/sign INIFAP-AAFC MOU

• Support by each government for “in-country” research

• Explore and identify funding sources for incremental and new research costs

• Explore and decide on call/review and approval of research projects between Mexico and Canada

issues.– In Mexico– Between Mexico and Canada

• Need for consistency and more frequent meetings.• Need for collaboration on research priorities AND

nutrition marketing strategy.• Need for immediate recognition of funding

requirements.

priority.

Take home message

The Canadian and Mexican bean industries are on the same page!

• Focus on demand through nutrition marketing (recognizing the need to balance with production fundamentals).

• We are interdependant. Cooperation on production issues, research priorities, and nutrition marketing is key for sector growth and increasing demand for beans.
