Gene structure of isoprene synthases and Arabidopsis terpene synthases
Exon (E) and intron (I) nucleotide length of isoprene synthases and the average and sd for 13 Arabidopsis terpene synthase genes with apparent transit sequences. Also shown is the total number of amino acids. The Arabidopsis genes used were At1g31950, At1g48800, At1g48800, At1g66020, At1g70080, At2g24210, At3g14520, At3g14540, At3g25810, At3g29110, At3g32030, At4g15870, and At5g44630. Values for introns are in italics.
