Abstract
Plant acylCoA dependent acyltransferases constitute a large specific protein superfamily named BAHD Using the conserved sequence motifs of BAHD members we searched the genome sequences of Populus and Arabidopsis and identified respectively 94 and 61putative genes Subsequently we analyzed the phylogeny gene structure and chromosomal distribution of BAHD members of both species then we profiled expression patterns of BAHD genes by “in silico” northern and microarrayanalyses based on public databases and by RTPCR While our genomic and bioinformatic analyses provided full sets of BAHD superfamily genes and cleaned up a few existing annotation errors importantly it led to our recognizing several unique Arabidopsis BAHD genes that inversely overlapped with their neighboring genes on the genome and disclosing a potential natural antisense regulation for gene expressions Systemic geneexpression profiling of BAHD members revealed distinct tissuespecific/preferential expression patterns indicating their diverse biological functions Our study affords a strong knowledge base for understanding BAHD members’ evolutionary relationships and gene functions implicated in plant growth development and metabolismAuthors would like to thank Dr Gray Tuskan in Oak Ridge National Laboratory for providing additional P trichocarpa plantlets This work was supported by the DOE USDA joint Plant Feedstock Genomics program Project no Bo135 and the Laboratory Directed Research and Development program LDRD07047 of Brookhaven National Laboratory under contract with Department of Energy to CJL
