A genomic map enriched for markers linked to Avr1 in Cronartium quercuum f.sp. fusiforme.

A novel approach is presented to map avirulence gene Avr1 in the basidiomycete Cronartium quercuum f.sp. fusiforme, the causal agent of fusiform rust disease in pines.

Evolution of genome size and complexity in Pinus.

Background: Genome evolution in the gymnosperm lineage of seed plants has given rise to many of the most complex and largest plant genomes, however the elements involved are poorly understood.

Methodology/principal Findings: Gymny is a previously undescribed retrotransposon family in Pinus that is related to Athila elements in Arabidopsis. Gymny elements are dispersed throughout the modern Pinus genome and occupy a physical space at least the size of the Arabidopsis thaliana genome.

Genetic interaction of the fusiform rust fungus with resistance gene fr1 in loblolly pine.

ABSTRACT We propose a method for defining DNA markers linked to Cronartium quercuum f. sp. fusiforme avirulence (Avr) genes.
