“…In the small area of Abraham's Bosom the complex pattern of differentiation forms a "graded patchwork" similar to that found in Agrostis tenuis (Bradshaw, 1959) and Eschscholtia ca4fornica (Cook, 1962) but on a much smaller scale.…”

“…It has been introduced to Chile, New Zealand, Tasmania and mainland Australia, where it has become naturalized. California poppy grows in a large range of different habitats and is highly variable in structure, and life history (Cook 1962). Additionally, shoot, inflorescence and flower morphogenesis has been studied in detail (Becker et al 2005).…”

The Floral Genome Project (FGP) selected California poppy (Eschscholzia californica Cham. ssp. Californica) to help identify new florally-expressed genes related to floral diversity in basal eudicots. A large, non-normalized cDNA library was constructed from premeiotic and meiotic floral buds and sequenced to generate a database of 9,079 high quality Expressed Sequence Tags (ESTs). These sequences clustered into 5,713 unigenes, including 1,414 contigs and 4,299 singletons. Homologs of genes regulating many aspects of flower development were identified, including those for organ identity and development, cell and tissue differentiation, cell cycle control, and secondary metabolism. Over 5% of the transcriptome consisted of homologs to known floral gene families. Most are the first representatives of their respective gene families in basal eudicots and their conservation suggests they are important for floral development and/or function. App. 10% of the transcripts encoded transcription factors and other regulatory genes, including nine genes from the seven major lineages of the important MADS-box family of developmental regulators. Homologs of alkaloid pathway genes were also recovered, providing opportunities to explore adaptive evolution in secondary products. Furthermore, comparison of the poppy ESTs with the Arabidopsis genome provided support for putative Arabidopsis genes that previously lacked annotation. Finally, over 1,800 unique sequences had no observable homology in the public databases. The California poppy EST database and library will help bridge our understanding of flower initiation and development among higher eudicot and monocot model plants and provide new opportunities for comparative analysis of gene families across angiosperm species.

“…In a species with more or less continuous distribution, there may be dines of varying slopes interspersed with rather sharp discontinuities corresponding to changes in the environment. Such a pattern of variation is perhaps best termed a graded patchwork and has been reported in Agrostis tenuis (Bradshaw, 1959), Eschscholtzia caljfornica (Cook, 1962) and other examples cited by these workers. As shown by Epling and Dobzhansky (1942) in Linanthus parryae, as well as by many other workers, the larger geographic subdivisions may give a greater degree of genetic divergence than the smaller microgeographic subdivisions.…”
