Mary Rumpho's group has published another paper on chloroplast symbiosis in Elysia chlorotica.
The reference is: Brian J. Green, Wei-Ye Li, James R. Manhart, Theodore C. Fox, Elizabeth J. Summer, Robert A. Kennedy, Sidney K.Pierce, and Mary E. Rumpho (2000) Mollusc-Algal Chloroplast Endosymbiosis. Photosynthesis, Thylakoid Protein Maintenance, and Chloroplast Gene Expression Continue for Many Months in the Absence of the Algal Nucleus. Plant Physiology, 124: 331-342.
The most significant findings are:
• 1. at least one algal nuclear encoded protein (a light harvesting complex protein) is maintained in the animal for 9 months in the absence of algal food.
• 2. there is no algal nuclear DNA in photosynthetically active animals
• 3. Chloroplast RFLP analysis supports field observations that Vaucheria litorea is the chloroplast source in the Martha's Vineyard (Massachusetts, USA) population of E. chlorotica - I think this is the first time molecular tools have been used for this sort of analysis.

Thanks for keeping us up to date with the work going on in Mary Rumpho's lab. From the emails I have had from students, there are a lot of biologists who find this topic fascinating. I have added the reference to my list of Chloroplast Symbiosis References.
