UBC discovery unlocks tree genetics, gives new hope for pine beetle defense

16.01.2008
UBC researchers have discovered some of the genetic secrets that enable pine and spruce trees to fight off pests and disease, uncovering critical new information about forests’ natural defense systems.

Assoc. Prof. Joerg Bohlmann says this genetic analysis will allow forest stewardship programs to reinforce a forest’s inherent strength, breeding trees that could in time repel insects such as British Columbia’s notorious mountain pine beetles.

Bohlmann and his research associate Christopher Keeling explored the genetic makeup of oleoresin within spruce, discovering a sophisticated ability to produce complex blends of chemicals that continuously evolve to protect the tree from changing conditions and challenges.

“Conifers are some of the oldest and longest living plants on the planet,” says Bohlmann. “We’ve opened the book to understanding how they can survive in one location for thousands of years despite attacks from generations of insects and diseases.”

Their study examines the molecular biochemistry of conifers interacting with genomes of bark beetles and bark beetle-associated fungal pathogens. Bohlmann’s study appears in today’s edition of the Proceedings of the National Academy of Sciences.

“Figuring out how these naturally occurring defenses work has important implications for the long-term sustainability and health of our forests,” says Bohlmann, who’s working with the B.C. Ministry of Forests and Range, the forestry industry and the Canadian Forest Service.

Bohlmann is also co-leader of the recently announced $4-million project that Genome BC and Genome Alberta is funding to investigate the mountain pine beetle infestation at the genomic level.

Insect pests and pathogens cause annual losses of billions of dollars to conifer-based forest economies in North America and Europe. In B.C., the mountain pine beetle epidemic has killed about 40 per cent of the pine forests since its first appearance in the mid 1990s.

This is the largest recorded bark beetle outbreak in Canada, leaving B.C. with 13 million hectares of grey and red dead pine – an area four times the size of Vancouver Island and a volume of dead timber equivalent to 530 million telephone poles.

Bohlmann is leading UBC’s and international research programs on forest health genomics. In 2006, Bohlmann and a team of international scientists completed the world’s first physical map and sequencing of a tree genome – the third plant ever sequenced.

He is based at UBC’s Michael Smith Laboratories, a multidisciplinary research facility. Bohlmann also holds teaching appointments in the departments of Botany and Forest Sciences and is an associate at UBC’s Wine Research Centre.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

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: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

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...
