Project name: New genomic resources and comparative analyses reveal differences in floral gene expression in selfing and outcrossing Collinsia sister species

Description: We used flower bud transcriptomes from Collinsia rattanii and its predominantly outcrossing sister species, C. linearis, to explore the genomic basis of mating system and phenotypic evolution in Collinsia, a self-compatible genus. Transcriptional regulation of enzymes involved in pollen formation may influence floral traits that distinguish selfing and outcrossing Collinsia species through pleiotropic functions. These patterns provide clues about parallel evolution in selfing plants.Overall design: We sampled 2-4 whole floral buds (= 1 sample) per bud stage from each of 3 individuals per species.

Data type: Transcriptome or Gene expression

Sample scope: Multiisolate

Relevance: Other
