1Warnell School of Forestry and Natural Resources, University of Georgia (UGA), 2Instituto de Biologia Experimental e Tecnológica, Instituto Tecnologia Química e Biológica UNL, Av. da República
The cDNA microarray PtGen2 was developed for gene expression studies in loblolly pine, P. taeda, and other conifer species. Here, we show pre- and post-hybridization handling and washing techniques that can be used with this array to yield better consistency, reduced artifacts, and lower backgrounds.

An Improved Method of RNA Isolation from Loblolly Pine (P. taeda L.) and Other Conifer Species
Warnell School of Forestry and Natural Resources, University of Georgia (UGA)
Many plant tissues, including phloem and xylem from loblolly pine (Pinus taeda L.), contain high levels of phenolics and polysaccharides that interfere with RNA purification. This presentation discusses techniques for the harvest of field-grown tissues and isolation of RNA of sufficient quality for microarrays and other genomic analyses.

Agar-Block Microcosms for Controlled Plant Tissue Decomposition by Aerobic Fungi
Department of Bioproducts and Biosystems Engineering, University of Minnesota
This video demonstrates a controlled environment approach to study degradation of lignocellulosic plant tissues by aerobic fungi. The ability to control nutrient sources and moisture is a key advantage of agar-block microcosms, but the approach often yields mixed success. We address critical pitfalls to yield reproducible, low-variability results.
