SI Leader: Anita Vijapura Spring 2010 BSC2011 02/22 Genetic Control of Flowering Flower formation involves a phase change from _________________ growth to __________________ growth. -Triggered by: The production of a flower by a _______________________ stops the _______________ growth of that organ. The protein products of the floral ____________________________ genes are transcription factors that regulate the genes required for the conversion into floral meristems. Thus, turning these genes on will induce the ______________________________ to flower and each leaf primordium that forms will develop into a specific type of __________________ based on _______________________________________. Describe the characteristic floral pattern (development of floral organs): 1) 2) 3) 4) The _________________________ genes (aka: ________________________) regulate the development of this

Unformatted text preview: floral pattern. What determines which of these genes are expressed in a particular floral organ primordium? And, what is the result? What results from a mutation in these genes? The ________ model of flower formation identifies how the _____ classes of floral organ identity genes direct the formation of the ______ types of floral organs. 1 SI Leader: Anita Vijapura Spring 2010 BSC2011 02/22 Each class of genes is switched on in __________ specific whorls of the floral meristem: 1) A: 2) B: 3) C: These genes regulate expression of other genes responsible for development of _________________________: 1) Sepals: 2) Petals: 3) Stamens: 4) Carpels: The ABC model can account for the _____________________ of mutants lacking A, B, or C gene activity. 2...
