Genetics of Food - Coggle Diagram

- - - - ex. carotene in corn: varies from almost nonexistent (white kernals) to lots of carotene (dark kernels)
      - ex. oil content in corn: select plants for low or high oil content --> even after 80 generations you are still able to vary oil content (bc there's a lot of genes involved)
      - ex. milk produced per cow: breeders can selectively choose cows that produce lots of milk
    - - ex. "string" beans are actually stringless beans
      - ex. green revolution on wheat production (high yield)
        
        choose dwarf varieties --> higher yields because dwarf varieties are less susceptible to lodging (short wheat doesn't get knocked over by wind)
        
        Gibberellin hormone in plants controls stem elongation
        
        dwarf mutations block biosynthesis (rice)/response (wheat) to GA (loss-of-function mutation)
        
        How? deletion in sd1
  - - - insect resistant (Bt protein)
      - resistance to herbicide roundup (mutant makes it resistant to glyphosate)
    - - BioCassava Plus
        
        increase content and bioavailability of zinc and iron
        
        increase protein content
        
        increase vitamin A and E
        
        increase cyanogen content
        
        delay rapid post-harvest physiological deterioration
        
        develop virus resistance
    - - transformed with a phytase gene from E. Coli, these pigs are able to digest phytate in their feed, reducing the amount of phosphorous in their manure
