Unveiling the Future of Beekeeping: Genomic Studies to Boost Honeybee Resilience
Beekeeping faces a significant challenge, with annual colony losses ranging between 30% and 40%, soaring to 60% in dire circumstances. The primary culprits are parasites and pathogens, prompting a need for innovative approaches to enhance honeybee resilience.
Revolutionizing Bee Breeding with Genomics
Traditionally, bee breeding methods have remained largely unchanged for nearly a century, even with the availability of affordable gene sequencing. Purdue University's Brock Harpur, along with Luiz Brito and Gregor Gorjanc, aims to usher in a new era. Their groundbreaking project, supported by an $11.6 million grant from the U.S. Department of Agriculture National Institute of Food and Agriculture, focuses on validating genomic breeding tools and designing a user-friendly system for bee breeders.
The Power of Genomic Resources
Despite the sequencing of the honeybee genome in 2006, widespread use of genomic technology in bee breeding has been limited. Harpur's team, leveraging the decreasing cost of genetic samples, now aims to empower beekeepers by providing them with valuable insights into their bees' genetic makeup. With prices dropping from $400 to approximately $50 per sample, genomic breeding techniques hold the potential to significantly increase beekeepers' profits.
A Hive of Genomic Data
Harpur's lab, operating a gene sequencing service for beekeepers, has sequenced nearly 2,000 samples from across the country. Beekeepers can send a bee to be sequenced, gaining valuable information about its genetic traits and origin. This extensive genomic database allows Harpur to assess how effectively genotypes predict breeding values under various conditions.
Simulating Success: Statistical Validity and Global Impact
Supercomputers at Purdue's Rosen Center for Advanced Computing enable Harpur's team to simulate various scenarios, determining the statistical validity of their approach and the necessary sample sizes. The researchers explore the impact of different populations on the predictions and evaluate the effectiveness of various genome sequencing methods.
A Local Start with Global Ambitions
Collaborating closely with national bee breeding organizations, Harpur's team has initiated trials and data collection with the Indiana Queen Breeders Association. The plan is to demonstrate the success of their approach locally before scaling it globally. Harpur envisions this project not only as a game-changer for bee breeding but also as a means to answer fundamental questions about the impact of artificial selection on the intricate social dynamics within bee colonies.
Bee Breeding and Beyond: A Confluence of Science and Practice
As an evolutionary biologist, Harpur sees this project as a unique opportunity to unravel the complexities of artificial selection on bee colonies consisting of thousands of genetically related individuals. Understanding how individual genomes contribute to collective traits and the dynamics of selection in such scenarios is a fundamental aspect that this groundbreaking initiative seeks to explore.
