Gene family evolution across the green tree of life.

The transcriptome database generated by the 1000 plants (1KP) initiative provides an unprecedented opportunity to investigate gene family evolution along the green branch of the tree of life. This database singularly accommodates a richer representation of the genes present in all major Viridiplantae lineages, including algae, bryophytes, lycophytes, monilophytes and seed plants, than previously assembled. These resources are crucial to elucidating the deep history of genes involved in the developmental genetics of modern plant taxa. We have used the 1KP database to investigate the evolution of several gene families with important roles in plant development; namely the GSK/Shaggy-like Kinases, Lateral Organ Boundary Domain, and select subfamilies of MADS-box genes. In addition, the inherent RNA-seq component of the 1KP transcriptomes was explored to survey the expression of floral MADS-box genes in a tissue-wise context. We will present examples where, in each of these studies, the 1KP database yielded data pivotal to addressing questions about gene family evolution, often providing new insights into their origin, diversification, and expression, during plant evolution.
