2. The BioClub is going to visit the Gulf of Maine Research Institute (on the waterfront in Portland) this Friday, March 14th You can meet outside of room 105 Science Building at 11:30 to carpool and will return to campus by 2:00.

3. A seminar this Friday:

4. 6.1 Arabidopsis thaliana thale cress or wall cress

5. Comparing animals and plants: Invented multicellularity independently No germ line cells in plants (plants are easy to clone. No maternal factors???) No morphogenesis in plants (very simple fate maps) Plant cells contain plasmodesmata (a type of gap junction between cells)

6. Comparing animals and plants: Invented multicellularity independently No germ line cells in plants (plants are easy to clone) No morphogenesis in plants (very simple fate maps) Plant cells contain plasmodesmata (a type of gap junction between cells) Fig. 1.23

7. FT mRNA is transcribed in leaves and then the mRNA goes through plasmodesmata on the way to cells in the shoot meristem where it is translated into a transcription factor protein that regulates transcription of genes for flowering. Fig. 6.35
