PLASTID FATTY ACID BIOSYNTHESIS IN THE DIATOMS NITZSCHIA ALBA AND NITZSCHIA LAEVIS

K.M. McGinnis, M.R. Sommerfeld
2000 Journal of Phycology  
We conclude that precursors for n-3 LC-PUFA biosynthesis in G. galatheanum may be acquired through ingestion of S. major , and may partially control feeding/photosynthesis in mixotrophic populations.  ...  Similarly, when data were compared among segments, there was no universal geographical pattern in tissue nutrients for all species.  ...  To reinforce molecular phylogenies, a robust morphological character database is necessary. For taxa with complex internal structures complete serial reconstruction is required.  ...
