Development of micropropagation protocols for the endangered gypsophile Arctomecon humilis (dwarf bear-poppy).

Arctomecon humilis (dwarf bear-poppy) is an endangered plant restricted to gypsum-rich soils of the Moenkopi formation that occur within 16 km2 of the St. George area in southern Utah. Habitat loss and degradation, attributable to extensive urban development and recreational use, have persistently posed the most serious threats to A. humilis populations. Additionally, the advance of invasive species and changes in pollinator mutualisms may also negatively impact plant survival. While propagation is considered critical for species recovery and management, documented efforts to propagate A. humilis from seed or tissue have been unsuccessful. The purpose of this ongoing study is to develop a protocol for in vitro micropropagation of A. humilis using leaf and meristem cultures. Successful shoot proliferation has been achieved in nutrient culture media containing various concentrations and combinations of plant growth regulators, representing a critical first step towards developing a protocol for producing mature plants in vitro. This development is a significant breakthrough in propagation research and conservation efforts for A. humilis. Continuing research is focused on improving growth conditions, inducing root organogenesis, and acclimating rooted plantlets to ex vitro conditions.
