Physiological genetics and environmental associations to aridity across the range of ponderosa pine (Pinus ponderosa)


Abstract: Ongoing global changes in temperatures and precipitation patterns are expected to result in greater water stress on trees in many areas, which may lead to increasing tree mortality. Ponderosa pine (Pinus ponderosa) is an ecologically and economically important tree species with a broad distribution in the western USA, which has been experiencing elevated mortality in many parts of California due to the recent severe drought. The aims of this proposal are: 1) to identify what genes in P. ponderosa are associated with spatial variation in aridity and 2) to test which physiological traits are involved in drought tolerance, and what genetic loci are associated with those traits. I will combine genotype association approaches with greenhouse experiments to achieve these aims. Understanding the traits conferring drought tolerance in seedlings and the genetic loci underlying them is key to understanding the responses of forests to climate change populations. This study has relevance to forest management and conservation, such as selecting proper seed sources for restoration and plantations.

When: Oct. 12th, Thursday, 12pm – 1pm
Where: SE2-302
