Sugars, hormones, and environment affect the dormancy status in underground adventitious buds of leafy spurge (Euphorbia esula) (2006)

Wun S. Chao, Marcelo D. Serpe, James V. Anderson, Russ W. Gesch, David P. Horvath

Signals from both leaves and apical or axillary meristems of leafy spurge are known to inhibit root bud growth. To test the hypothesis that carbohydrates and growth regulators affect root bud growth,...

Transcriptome analysis of paradormancy release in root buds of leafy spurge (Euphorbia esula) (2005)

David P. Horvath, Mauricio Soto-Suárez, Wun S. Chao, Ying Jia, James V. Anderson

Bud dormancy is the primary mechanism by which the many perennial weeds escape herbicidal and mechanical control. We developed a 2,654-element Euphorbiaceae cDNA microarray using 1,886 sequenced...

Cloning, characterization, and expression of growth regulator CYCLIN D3-2 in leafy spurge (Euphorbia esula) (2005)

David P. Horvath, James V. Anderson, Ying Jia, Wun S. Chao

We have isolated both a genomic and near full length cDNA clone for a D-class cyclin gene from the perennial weed leafy spurge. Sequence analysis indicates that this gene has the highest similarity...

Identification of genes induced in emerging tillers of wild oat (Avena fatua) using Arabidopsis microarrays (2003)

David P. Horvath, Robert Schaffer, Ellen Wisman

Arabidopsis complementary DNA (cDNA) microarrays were hybridized with labeled cDNA from mature leaves and emerging tillers of wild oat to determine if they could identify gene expression profiles in...

A molecular approach to understanding root bud dormancy in leafy spurge (2002)

David P. Horvath, James V. Anderson

Leafy spurge is a tenacious perennial weed of the Northern Plains. This plant maintains a perennial growth cycle by controlled production and growth of numerous underground adventitious buds. We are...

Review: A current review on the regulation of dormancy in vegetative buds (2001)

James V. Anderson, Wun S. Chao, David P. Horvath

In this review, we examine current techniques and recent advances directed toward understanding cellular mechanisms involved in controlling dormancy in vegetative propagules. Vegetative propagules...

Random sequencing of cDNAs and identification of mRNAs (2001)

James V. Anderson, David P. Horvath

As a first step toward developing a genomics-based research program to study growth and development of underground adventitious shoot buds of leafy spurge, we initiated a leafy spurge expressed...

Molecular Analysis of Signals Controlling Dormancy and Growth in Underground Adventitious Buds of Leafy Spurge

Horvath, David P., Chao, Wun S., Anderson, James V.

Dormancy and subsequent regrowth of adventitious buds is a critical physiological process for many perennial plants. We have used the expression of hormone and cell cycle-responsive genes as markers...

Molecular Cloning and Expression of cor (Cold-Regulated) Genes in Arabidopsis thaliana1

Hajela, Ravindra K., Horvath, David P., Gilmour, Sarah J., Thomashow, Michael F.

We have previously shown that changes in gene expression occur in Arabidopsis thaliana. L. (Heyn) during cold acclimation (SJ Gilmour, RK Hajela, MF Thomashow [1988] Plant Physiol 87: 745-750). Here...
