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.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
