ALM positions in lines TU2562 and EA485. Micrographs on the left show examples of the positions of the FLPs, AVM and ALMs in TU2562 and EA485. The animals are positioned with anterior to the left. White areas are cells expressing green fluorescent protein. Bar graphs on the right show the number of ALMs at each position in 100 animals from each strain. The ALM positions in TU2562 were similar to those in wild type animals whereas the ALMs in EA485 were located significantly anterior to their normal positions. The system for scoring ALM positions is described in Figure 1.
