    Notes: Abstract  We have studied the formation of Drosophila mushroom bodies using enhancer detector techniques to visualize specific components of these complex intrinsic brain structures. During embryogenesis, neuronal proliferation begins in four mushroom body neuroblasts and the major axonal pathways of the mushroom bodies are pioneered. During larval development, neuronal proliferation continues and further axonal projections in the pedunculus and lobes are formed in a highly structured manner characterized by spatial heterogeneity of reporter gene expression. Enhancer detector analysis identifies many genomic locations that are specifically activated in mushroom body intrinsic neurons (Kenyon cells) during the transition from embryonic to postembryonic development and during metamorphosis.

    Notes: Abstract Chromosome numbers for 9 tribes and 73 genera ofRutaceae are examined for the probable chromosome base numbers in these taxa. There is abundant dysploidy and infrageneric polyploidy in the largeRutoideae/Toddalioideae complex. We found that x = 18 was typical for the tribesZanthoxyleae andToddalieae; probably ancestral in theBoronieae and perhaps in theRuteae, Diosmieae, andCusparieae; and characteristic of subfamilyFlindersioideae. Considering the basic position of elements ofZanthoxyleae andToddalieae in the family it appears that diploid x = 18 is ancestral in theRutaceae. The morphologically advancedCitroideae are invariant for x = 9 and may be a product of dysploid reduction.
