The Role Of Carotenoid Cleavage Dioxygenase 4 In Flower Color Of The Allopolyploid Brassica Napus, Leanne Denice Fogg
Master's Theses
Allopolyploids are formed by interspecific hybridization and whole genome duplication, with the resulting organism contains multiple distinct subgenomes in one nucleus. Subgenomic interactions result in massive genetic and epigenetic reconstruction, contributing to variable phenotypic traits noted in newly formed allopolyploids. To better understand these mechanisms in the context of molecular biology, evolution, and plant breeding, plant biologists study the model organism Brassica napus (farmed as canola or oilseed rape). With white-flowering and yellow-flowering progenitors, flower color phenotype of B. napus presents an opportunity to examine subgenomic interactions. CAROTENOID CLEAVAGE DIOXYGENASE 4 (CCD4) is known to play a major …
