Research led by Wayne State discovers single gene in bees separating queens from workers

03.02.2014
Discovery may provide key to increasing agricultural economy in Michigan and beyond

A research team led by Wayne State University, in collaboration with Michigan State University, has identified a single gene in honeybees that separates the queens from the workers.

The scientists unraveled the gene's inner workings and published the results in the current issue of Biology Letters. The gene, which is responsible for leg and wing development, plays a crucial role in the evolution of bees' ability to carry pollen.

"The gene — Ultrabithorax, or Ubx — is responsible for making hind legs different from fore legs so they can carry pollen" said Aleksandar Popadic, associate professor of biological sciences in Wayne State University's College of Liberal Arts and Science and principal investigator of the study. "In some groups, like crickets, Ubx is responsible for creating a 'jumping' hind leg. In others, such as bees, it makes a pollen basket — a 'naked,' bristle-free leg region that creates a space for packing pollen."

"Other studies have shed some light on this gene's role in this realm, but our team examined in great detail how the modifications take place," added Zachary Huang, MSU entomologist.

Ubx represses the development of bristles on bees' hind legs, creating a smooth surface that can be used for packing pollen. This important discovery can be used as a foray into more commercial studies focused on providing means to enhance a bee's pollination ability – the bigger the pollen basket, the more pollen that can be packed in it and transported back to the hive.

While workers have these distinct features, queens do not. The team confirmed this by isolating and silencing Ubx. This made the pollen baskets completely disappear, altered the growth of the pollen comb and reduced the size of the pollen press. Interestingly, Ubx is also expressed in the same region of the hind legs in bumble bees, which are in the same family as honey bees. This finding suggests that the evolution of the pollen-gathering apparatus in all corbiculate bees may have a shared origin and could be traced to the acquisition of novel functions by Ubx.

In another interesting finding, researchers identified that bees living in more complex social structures have an advantage over isolated populations in developing these important functions.

"The pollen baskets are much less elaborate or completely absent in bees that are less socially complex," Huang said. "We conclude that the evolution of pollen baskets is a major innovation among social insects and is tied directly to more complex social behaviors."

The value of agricultural crops dependent on honey bee pollination was estimated to be $14.6 billion per year in the U.S. in 2013.

"In Michigan alone, the fruit and vegetable industries produce over $2 billion per year, and nearly 50 percent of that value is due entirely to honey bee pollination," said Huang. "This shows that bees are contributing significantly to the state and national economy."

This study, along with future research by Popadic and Huang, may provide an option for improving the shrinking population of bees' pollen-collecting capacity, leading to increased pollination and hopeful increases in fruit and vegetable production.

This research was funded to Popadic by the National Institute of General Medical Sciences of the National Institutes of Health, number GM071927.

Wayne State University is one of the nation's pre-eminent public research universities in an urban setting. Through its multidisciplinary approach to research and education, and its ongoing collaboration with government, industry and other institutions, the university seeks to enhance economic growth and improve the quality of life in the city of Detroit, state of Michigan and throughout the world.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
