Figure 2.

Schematic representation of the Arabidopsis FLAs deduced from DNA sequence (see “Materials and Methods” for accession nos.). The FLAs are grouped into four groups (A-D) based on phylogenetic analysis and pair-wise sequence comparison (see “Results”). The protein backbone of FLAs contains either one or two fasciclin-like domains (blue) and one or two AGP regions (red; Gaspar et al., 2001). Only the gene for FLA1 is predicted to have an intron, the position of which is indicated by a triangle, and where there are no ESTs, FLA names are bold and italicized. FLAs are predicted to contain an N-terminal secretion signal (white), and 14 of the 21 FLAs have a C-terminal signal for addition of a GPI anchor (green with white arrow; Schultz et al., 2002). Additional protein regions are shown in light gray. The longest FLA is FLA16 with 475 amino acids, and the shortest is FLA19 with 248 amino acids.
