Analysis of the WUSCHEL-RELATED HOMEOBOX gene family in the conifer picea abies reveals extensive conservation as well as dynamic patterns.

ABSTRACT:

Background

Members of the WUSCHEL-RELATED HOMEOBOX (WOX) gene family have important functions during all stages of plant development and have been implicated in the development of morphological novelties during evolution. Most studies have examined the function of these genes in angiosperms and very little is known from other plant species.

Results

In this study we examine the presence and expression of WOX genes in the conifer Picea abies. We have cloned 11 WOX genes from both mRNA and genomic DNA and examined their phylogenetic relationship to WOX genes from other species as well as their expression during somatic embryogenesis and in adult tissues.

Conclusions

Our study shows that all major radiations within the WOX gene family took place before the angiosperm-gymn
