Landels-Hill Big Creek Reserve

06 Jul, 09 AM - 08 Jul, 09 AM

The Papaveraceae plant family has many species that are self-incompatible annuals, a mechanism that ensures outcrossing among genetically different individuals. Despite this advantage, there may also be limitations to this reproductive strategy when populations are greatly reduced due to lack of compatible mates or when individuals are scattered across long distances. We have identified S-locus gene in several species in the Papaveraceae and are surveying the genus Eschscholzia to determine whether a homologous system of SI is present. The well known E. californica is a known self-incompatible species while another less frequent species Eschscholzia caespitosa may also be self-incompatible as it is one of the few Escscholzia species (outside of E. californica) that has not undergone an allopolyploid hybridization event. Polypoidy typically disrupts S-locus function. Current Escscholzia populations under study include Hastings Natural History Reservation, Antelope Valley Poppy Reserve, and with future potential sites to include Ansa Borego State Park. Landels-Hill Big Creek has known Eschscholzia caespitosa and E. californica. I hope to collect some stylar and leaf tissue from Eschscholzia caespitosa upon verification of its presence at the reserve.
