Genome scale transcriptome analysis and development of reporter systems for studying shoot organogenesis in poplar

Creator:

Bao, Yanghuan

Abstract:

Vegetative propagation allows the amplification of selected genotypes for research, breeding, and commercial planting. However, efficient in vitro regeneration and genetic transformation remains a major obstacle to research and commercial application in many plant species. Our aims are to improve knowledge of gene regulatory circuits important to meristem organization, and...

Heat balance of alcoves on the Willamette River, Oregon

Creator:

Bryenton, Andrew G.

Abstract:

Alcoves in some river systems are cooler than the mainstem of the river and provide thermal refugia for aquatic species. An energy balance and sensitivity analysis on 3 alcoves in the Willamette River, Oregon indicate that alcove size and alcove flux determine the degree to which meteorological conditions affect the...

Influence of hyporheic flow and geomorphology on temperature of a large, gravel-bed river, Clackamas River, Oregon, USA

Creator:

Burkholder, Barbara K.

Abstract:

The hyporheic zone influences the thermal regime of rivers, buffering temperature by storing and releasing heat over a range of timescales. We examined the relationship between hyporheic exchange and temperature along a 24-km reach of the lower Clackamas River, a large gravel-bed river in northwestern Oregon (median discharge = 75.7...
