Summary of evidence for evolutionary origins of Arabidopsis thaliana lineage-specific genes. The number of LSGs that fit each evolutionary scenario tested, plus the number of LSGs without elucidated origins. Support for gene model expression provided by an EST or cDNA consistent with the of gene model (as listed by TAIR). Support of expression at the locus provided by EST, cDNA or microarray probeset (TAIR and Ath1 affymetrix microarray).
