American Society of Plant Biologists Annual Meeting. ABSTRACT. Interpretive Summary: Technical Abstract: The tropical cut flower and potted plant Anthurium was popularized worldwide in part by pioneering flower growers, breeders and shippers in Hawaii along with the innovative ornamental research program that continues at the University of Hawaii. At the USDA, one of the research areas supporting Anthurium cultivar improvement involves generation of foundational resources for development of novel traits including floral color. Recent research advances in this area include metabolomic analysis of Anthurium floral flavonoid pools by LC/MS that has resulted in high resolution metabolic fingerprints of anthocyanin pigment and other flavonoid levels for biochemical phenotype identification and characterization of cultivars and parental species. Anthurium lacks a good model plant system and cultivars take as long as 10 to 15 years to develop due to generation times as long as two to three years from seed to flower. Thus, other research tools to augment Anthurium cultivar development include gene mining for novel color or other floral traits, use of microbial platforms for rapid validation of anthocyanin biosynthesis gene enzymatic function and plant biotechnology. |
