[…] The protein sequence of the root barley (H. vulgare) plastidial P2-G6PDH was retrieved from the NCBI database ( and used to search against other genomes using BlastP or tblastn. All the sequences are available at the following websites: for A. thaliana (, Oryza sativa (, Sorghum bicolor (, N. tabacum (, Populus trichocarpa (, Solanum tuberosum (, Triticum aestivum (, and Spinacia oleracea ( All protein accession numbers used in this article can be found in these databases.The amino acid alignments were performed using ClustalW ( and the phylogenetic tree was constructed using the Neighbor–Joining tree algorithm in MEGA version 4 ().Supplemental data files available at JXB online contain all the protein sequences indexed in this study including the accession numbers. [...] The amplified products were resolved on a 1.5% agarose gel, and the DNA was visualized by ethidium bromide, using an UV transilluminator, and images were acquired by a camera. Each gel photo was processed using Image J (NIH) to obtain a threshold black and white pixel map. The spots were quantified as arbitrary units (pixel) in an Excel worksheet, and used to construct a graph using the Sigmaplot (Jandel) software. The experiment shown is representative of three experiments which showed the same general behaviour; the average values and the standard errors are given in the chart below the gel photos in the figures.
