Microrna319-Mediated Gene Regulatory Network Impacts Leaf Development And Morphogenesis In Poplar, Yanxia Cheng, Lihu Wang, Manzar Abbas, Xiong Huang, Qiao Wang, Aimin Wu, Hairong Wei, Et. Al.

Michigan Tech Publications, Part 1

MicroRNA319 (miR319) has been implicated in leaf development in a number of plant species. Here we study the roles of miR319a and its regulated network in leaf development in poplars. Over-expression of miR319a in Populus alba × Populus glandulosa caused dwarf statures, narrow leaf blades and serrated leaf margins. The vascular bundles and bundle sheaths in transgenic leaves had more layers of cells than those in the leaves of control plants, indicating enhanced lignification in these cells. Among the 93 putative targets of miR319a predicted with the psRNATarget tool, only three genes, TCP (TEOSINTE BRANCHED1, CYCLOIDEA, and …

76-Year Decline And Recovery Of Aspen Mediated By Contrasting Fire Regimes: Long-Unburned, Infrequent And Frequent Mixed-Severity Wildfire, Cerena J. Brewen, John-Pascal Berrill, Martin W. Ritchie, Kevin Boston, Christa M. Dagley, Bobette Jones, Michelle Coppoletta, Coye L. Burnett

Aspen Bibliography

Quaking aspen (Populus tremuloides) is a valued, minor component on northeastern California landscapes. It provides a wide range of ecosystem services and has been in decline throughout the region for the last century. This decline may be explained partially by the lack of fire on the landscape due to heavier fire suppression, as aspen benefit from fire that eliminates conifer competition and stimulates reproduction through root suckering. However, there is little known about how aspen stand area changes in response to overlapping fire. Our study area in northeastern California on the Lassen, Modoc and Plumas National Forests has …

Consequences Of Increased Variation In Peatland Hydrology For Carbon Storage: Legacy Effects Of Drought And Flood In A Boreal Fen Ecosystem, Evan Kane, Catherine M. Dieleman, Danielle L. Rupp, Kevin H. Wyatt

Michigan Tech Publications, Part 1

Globally important carbon (C) stores in boreal peatlands are vulnerable to altered hydrology through changes in precipitation and runoff patterns, groundwater inputs, and a changing cryosphere. These changes can affect the extent of boreal wetlands and their ability to sequester and transform C and other nutrients. Variation in precipitation patterns has also been increasing, with greater occurrences of both flooding and drought periods. Recent work has pointed to the increasing role of algal production in regulating C cycling during flooded periods in fen peatlands, but exactly how this affects the C sink-strength of these ecosystems is poorly understood. We evaluated …

Fire Alters Plant Microbiome Assembly Patterns: Integrating The Plant And Soil Microbial Response To Disturbance, Nicholas C. Dove, Dawn M. Klingeman, Alyssa A. Carrell, Melissa A. Cregger, Christopher W. Schadt

Aspen Bibliography

• It is increasingly evident that the plant microbiome is a strong determinant of plant health. While the ability to manipulate the microbiome in plants and ecosystems recovering from disturbance may be useful, our understanding of the plant microbiome in regenerating plant communities is currently limited.
• Using 16S ribosomal RNA (rRNA) gene and internal transcribed spacer (ITS) region amplicon sequencing, we characterized the leaf, stem, fine root, rhizome, and rhizosphere microbiome of < 1-yr-old aspen saplings and the associated bulk soil after a recent high-intensity prescribed fire across a burn severity gradient.
• Consistent with previous studies, we found that soil microbiomes are responsive to fire. We extend these findings by showing that certain plant tissue microbiomes also change in response to …

Future Dominance By Quaking Aspen Expected Following Short-Interval, Compounded Disturbance Interaction, Robert A. Andrus, Sarah J. Hart, Niko Tutland, Thomas T. Veblen

Aspen Bibliography

The spatial overlap of multiple ecological disturbances in close succession has the capacity to alter trajectories of ecosystem recovery. Widespread bark beetle outbreaks and wildfire have affected many forests in western North America in the past two decades in areas of important habitat for native ungulates. Bark beetle outbreaks prior to fire may deplete seed supply of the host species, and differences in fire‐related regeneration strategies among species may shift the species composition and structure of the initial forest trajectory. Subsequent browsing of postfire tree regeneration by large ungulates, such as elk (Cervus canadensis), may limit the capacity …
