Current draft annotations for sequenced conifer genomes are preliminary and limited, but provide opportunities for further structural and functional analysis. We attempted to improve the existing genome annotations by marking 5’-UTRs in the four conifer species Pinus taeda, Picea glauca, Picea abies and Larix sibirica. Prediction of transcription start sites (TSS) was performed on the promoter sequences of genes with RNA or protein support using TSS prediction program TSSPlant. The distribution of 5’-UTR lengths from the annotations of several model plants was used to select the best prediction per gene. Frequency of TATA(A/T)A(A/T) motif in the predicted TSS-centered promoter regions showed a pronounced peak around 60 bp upstream of TSS.
