binding factor)• Sites of E-box and MEF-box on muscle differentiation-specific
genes• Combinatorial codes to specify distinct cell fates along D/V axis• Lhx3, an effector gene for V2 differentiation is not repressed in the
p2 domain• Common signaling pathways in development• Three habits to signal effectively and specifically

Plant Development
Lecturer: Dr. Shu-Hsing Wu(IPMB)
Why plants?
What are the current status of developmental biology in plants?1. Embryogenesis2. Vegetable growth: meristems and leaf development3. Flowering time control4. Reproductive growth: flower development
Evo-Devo
Lecturer: Dr. Jr-Kai Yu (ICOB)

Development and Diseases
Lecturer: Dr. June-Tai Wu(NTU)
The lecture will mainly cover three topics:
1) diseases related to anatomical defects introducing birth defects that
reflect abnormalities in patterning during intrauterine development
2) diseases related to functional defects introducing genetic diseases
resulted from defects in terminal differentiation of a tissue
3) psychiatric disease related to development introducing the
developmental basis of psychiatric diseases, such as autism and
schizophrenia.
