Molecular Plant Pathology
Expertise and Instrumentation: Fungal diseases of crop species, plant-fungal interactions, molecular genetics, functional genomics. metabolomics, mycology 

Complex, molecular-level interactions between plants and pathogens ultimately determine the extent to which disease develops.  Research in my lab takes systems-based approaches to characterize molecular mechanisms underlying diseases of crop species.   In general, our research addresses the following fundamental questions:

• How is pathogenesis regulated in fungi and what are the links between diverse components
of pathogenesis, e.g., morphological differentiation, conidiation, and secondary metabolism?
• What are the environmental cues that trigger pathogenesis in fungi and how are they
perceived?
• To what extent is the genetic regulation of pathogenesis conserved among fungal
pathogens?
• How do plants respond to pathogens at the molecular level and what genes are involved?

We blend a wide range of techniques and approaches in our research, including conventional and molecular genetics, functional, comparative, and evolutionary genomics, analytical chemistry, and metabolomics to explore the basis of both fungal pathogenesis and host resistance.  Areas of particular interest include kernel-rotting diseases caused by mycotoxigenic fungi, such as Aspergillus flavus, Fusarium verticillioides, and Fusarium graminearum; foliar diseases caused by species of Cercospora, including C. zeae-maydis and C. kikuchii; and diseases caused by necrotrophic fungi, such as Botrytis cinerea.  

Research Accomplishments (2018)

  • Frogeye leaf spot of soybean is one of the most problematic foliar diseases of soybean in Arkansas and the U.S.  Anecdotally, new races of the pathogen are thought to have emerged, but rigorous data have not been available to support this concern.  In 2018, the Bluhm lab confirmed the existence of new (more virulent) races of the pathogen, and mapped at least one gene associated with race specificity in the pathogen.  The Bluhm lab also provided the soybean community an updated assessment of the predominant races of the pathogen throughout the U.S. This information is crucial for soybean breeders, and provides a foundation to create molecular assays to identify races of the pathogen.
  • Rcs3 (from soybean cultivar Davis) is the last known bastion of genetic resistance to frogeye leaf spot of soybean.  Rcs3 has been deployed widely, and there are serious concerns about how to control the disease if/when the pathogen evolves the ability to overcome Rcs3.  In 2018, the Bluhm lab identified and confirmed five distinct isolates of the pathogen that can overcome Rcs3.  The molecular dissection of how these isolates can overcome Rcs3 is underway.  The discovery of these strains provides the soybean community advance warning that new sources of genetic resistance are urgently needed.
  • Cercospora leaf blight of soybean is increasingly problematic for Arkansas growers.  Management options are limited and effective genetic resistance has not been identified.  In 2018, the Bluhm lab sequenced the genomes of 24 strains of the pathogen from across the U.S.  This information clarified that a new species of the pathogen has become predominant and widespread, which is critical information for coordinating efforts of plant breeders.
  • In 2018, unfavorable environmental conditions led to serious, widespread reductions in soybean seed quality, most of which resulted from outbreaks of seedborne diseases.  The Bluhm lab performed field experiments utilizing soybean diversity panels to determine the genetic basis of resistance to seedborne diseases, an area that is surprisingly understudied.  Soybean seed quality segregated in the diversity panel, which has facilitated association mapping to identify soybean genes underlying resistance and susceptibility.
  • Phomopsis seed decay is one of the most common seedborne diseases of soybean.  To date, very little information is available regarding how the pathogen shifts from endophytic to necrotrophic growth.  In 2018, the Bluhm lab utilized molecular genetics to identify key genes in the pathogen that regulate virulence.  To date, these are the only described pathogenicity genes in this organism, and will provide potential targets for transgenic resistance via host-induced gene silencing.
  • New ways to control mycotoxins are urgently needed for Arkansas corn production.  In 2018, the Bluhm lab developed and evaluated multiple sources of transgenic resistance. In greenhouse assays, mycotoxin accumulation was reduced by as much as 90%.  Avenues for commercialization are being explored via licensing and the formation of a start-up company.
  • To help growers learn more about mycotoxins and existing, practical tools for management, the Bluhm lab maintained a smartphone app titled: Mycotoxins.  Available for free in Android and Apple formats, the app condenses recent research about management options into clear recommendations and information modules.
  • To accelerate genetic resistance to downy mildew in vegetables and ornamentals, the Bluhm lab collaborated with the Correll lab to map resistance genes in spinach and create molecular markers for breeders.  Knowledge from spinach will ultimately steer efforts in vegetable crops and ornamentals of importance to Arkansas agriculture.
  • In 2018, Bluhm gave invited plenary talks at one international and two regional meetings.  Other members of the Bluhm lab presented talks at regional, national, and international venues documenting research findings.
  • Research productivity:  In 2018, the Bluhm lab produced 9 articles for peer-reviewed journals (7 published, 2 submitted and currently in peer review).  Numerous additional manuscripts are in preparation.
  • Grantsmanship:  In 2018, PI Bluhm was supported by 10 extramural grants, with over $500,000 allocated directly to his program this year.  Funding came from diverse sources, including NSF, USDA-NIFA, and various commodity boards/organizations.  Three additional grants are pending.

Burt Bluhm and Alex Zaccaron created Mycotoxins, a smartphone App that provides growers and other stakeholders practical information about how to identify, and remediate, mycotoxin problems in corn.  The Apple version became available in November, 2017; an Android version was released in March, 2018.

Mycotoxins was downloaded from the Apple Store 497 times from 12/01/2017 to 11/29/2018. Most of the users (81%) are from the US, followed by Canada, Italy, and various other countries. In the same period, Mycotoxins has been downloaded from Google Play at least 100 times (exact download numbers are not currently available), and has received an average review score of 4.9 out of 5 stars.
