Discovery of a bud-break gene could lead to trees adapted for a changing climate

in Oregon in a hundred years?" said Strauss. "That depends on the natural diversity that we have and how much the environment changes. Will there be sufficient genetic diversity around to evolve populations that can cope with a much warmer and likely drier climate? We just don't know."

Strauss called the confirmation of the bud-break gene which scientists named EBB1 for short a "first step" in developing the ability to engineer adaptability into trees in the future.

"Having this knowledge enables you to engineer changes when they might become urgent," he said.

Yordan Yordanov and Victor Busov at Michigan Tech worked with Cathleen Ma and Strauss at Oregon State to trace the function of EBB1 in buds and other plant tissues responsible for setting forth the first green shoots of spring. They developed modified trees that overproduced EBB1 genes and emerged from dormancy earlier in the year. They also showed that trees with less EBB1 activity emerged from dormancy later.

"The absence of EBB1 during dormancy allows the tree to progress through the physiological, developmental and adaptive changes leading to dormancy," said Busov, "while the expression of EBB1 in specific cell layers prior to bud-break enables reactivation of growth in the cells that develop into shoots and leaves, and re-entry into the active growth phase of the tree."

The study began when Strauss noticed poplar trees emerging earlier than others in an experimental field trial at Oregon State. One April morning, he found that four seedling trees in a 2.5-acre test plot were putting forth leaves at least a week before all the other trees. Strauss and Busov, a former post-doctoral researcher at Oregon State, led efforts to identify the genes responsible.

They found that EBB1 codes for a protein that helps to restart cell division in a part of the tree known as meristem, which is analogous to stem cells in animals. EBB1 also plays a role in suppressing
