Tree-ring stable isotopes record the impact of a foliar fungal pathogen on CO₂ assimilation and growth in Douglas-fir

Creator:: Saffell, Brandy J., Meinzer, Frederick C., Voelker, Steven L., Shaw, David C., Brooks, J. Renée, Lachenbruch, Barbara, and McKay, Jennifer
Abstract:: Swiss needle cast (SNC) is a fungal disease of Douglas-fir (Pseudotsuga menziesii) that has recently become prevalent in coastal areas of the Pacific Northwest. We used growth measurements and stable isotopes of carbon and oxygen in tree-rings of Douglas-fir and a non-susceptible reference species (western hemlock, Tsuga heterophylla) to evaluate...

Seasonal carbohydrate dynamics and growth in Douglas-fir trees experiencing chronic, fungal-mediated reduction in functional leaf area

Creator:: Saffell, Brandy J., Meinzer, Frederick C., Woodruff, David R., Shaw, David C., Voelker, Steven L., Lachenbruch, Barbara, and Falk, Kristen
Abstract:: Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which...

Drivers of radial growth and carbon isotope discrimination of bur oak (Quercus macrocarpa Michx.) across continental gradients in precipitation, vapour pressure deficit and irradiance

Creator:: Voelker, Steven L., Meinzer, Frederick C., Lachenbruch, Barbara, Brooks, J. Renee, and Guyette, Richard P.
Abstract:: Tree-ring characteristics are commonly used to reconstruct climate variables, but divergence from the assumption of a single biophysical control may reduce the accuracy of these reconstructions. Here, we present data from bur oaks (Quercus macrocarpa Michx.) sampled within and beyond the current species bioclimatic envelope to identify the primary environmental...

Spring temperature responses of oaks are synchronous with North Atlantic conditions during the last deglaciation

Creator:: Voelker, Steven L., Noirot-Cosson, Paul-Emile, Stambaugh, Michael C., McMurry, Erin R., Meinzer, Frederick C., Lachenbruch, Barbara, and Guyette, Richard P.
Abstract:: Paleoclimate proxies based on the measurement of xylem cell anatomy have rarely been developed across the temperature range of a species or applied to wood predating the most recent millennium. Here we describe wood anatomy-based proxies for spring temperatures in central North America from modern bur oaks (Quercus macrocarpa Michx.)....

Hydraulic architecture of two species differing in wood density: opposing strategies in co-occurring tropical pioneer treespce_2421 116..

Creator:: McCulloh, Katherine A., Johnson, Daniel M., Meinzer, Frederick C., Voelker, Steven L., Lachenbruch, Barbara, and Domec, Jean-Christophe
Abstract:: Co-occurring species often have different strategies for tolerating daily cycles of water stress. One underlying parameter that can link together the suite of traits that enables a given strategy is wood density. Here we compare hydraulic traits of two pioneer species from a tropical forest in Panama that differ in...

Antisense down-regulation of 4CL expression alters lignification, tree growth and saccharification potential of field-grown poplar

Creator:: Voelker, Steven L., Lachenbruch, Barbara, Meinzer, Frederick C., Jourdes, Michael, Ki, Chanyoung, Patten, Ann M., Davin, Laurence B., Lewis, Norman G., Tuskan, Gerald A., Gunter, Lee, Decker, Stephen R., Selig, Michael J., Sykes, Robert, Himmel, Michael E., Kitin, Peter, Shevchenko, Olga, and Strauss, Steven H.
Abstract:: Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...

Comparative hydraulic architecture of tropical tree species representing a range of successional stages and wood density

Creator:: McCulloh, Katherine A., Meinzer, Frederick C., Sperry, John S., Lachenbruch, Barbara, Voelker, Steven L., Woodruff, David R., and Domec, Jean-Christophe
Abstract:: Plant hydraulic architecture (PHA) has been linked to water transport sufficiency, photosynthetic rates, growth form and attendant carbon allocation. Despite its influence on traits central to conferring an overall competitive advantage in a given environment, few studies have examined whether key aspects of PHA are indicative of successional stage, especially...

Tyloses and phenolic deposits in xylem vessels impede water transport in low-lignin transgenic poplars: a study by cryo-fluorescence microscopy

Creator:: Kitin, Peter, Voelker, Steven L., Meinzer, Frederick C., Beeckman, Hans, Strauss, Steven H., and Lachenbruch, Barbara
Abstract:: Of 14 transgenic poplar genotypes (Populus tremula × Populus alba) with antisense 4-coumarate:coenzyme A ligase that were grown in the field for 2 years, five that had substantial lignin reductions also had greatly reduced xylem-specific conductivity compared with that of control trees and those transgenic events with small reductions in...

Transgenic poplars with reduced lignin show impaired xylem conductivity, growth efficiency and survival

Creator:: Voelker, Steven L., Lachenbruch, Barbara, Meinzer, Frederick C., Kitin, Peter, and Strauss, Steven H.
Abstract:: We studied xylem anatomy and hydraulic architecture in 14 transgenic insertion events and a control line of hybrid poplar (Populus spp.) that varied in lignin content. Transgenic events had different levels of down‐regulation of two genes encoding 4‐coumarate:coenzyme A ligase (4CL). Two‐year‐old trees were characterized after growing either as free‐standing...
