DESCRIPTION:Changes in both protein-coding sequence and gene expression un
 derlie the evolution of phenotypic differences between species (King and W
 ilson\, 1975). Expression levels and patterns of orthologous genes are hig
 hly conserved between mammals (Brawand et al.\, 2011\; Merkin et al.\, 201
 2). To uncover the evolutionary dynamics of protein-coding and non-coding 
 gene expression in flowering plants\, we sequenced the transcriptomes from
  nine organs across seven species\, and compared our results with the publ
 ished mammalian data sets. We found that gene expression levels evolve rap
 idly in plants\; within 45 million years\, expression levels of orthologou
 s genes diverged so strongly that they are more similar between different 
 organs within a species than between homologous organs from different spec
 ies. Meristematic tissues and leaf show the highest degree of expression c
 onservation\, whereas stamen and pollen display the fastest evolving trans
 criptomes. To make our data easily accessible\, we developed a platform fo
 r interactive data analysis and visualization.\n
