A conserved flp-28/29, flp-3 and flp-2/30 gene cluster.

The location of flp-29 and/or flp-30 in the same genomic environment as flp-28 and flp-2 respectively provides evidence to support their redesignation. flp-28/29, flp-3 and flp-2/30 (green, red and yellow arrows respectively) gene sequelogue locations are shown relative to the fourth and fifth exons of a glutamate synthase gene (W07E11.1) in C. elegans, and in four parasitic nematode species (blue arrows). The direction of each arrow indicates gene orientation. Introns of flp genes are not displayed. One representative species from each clade (excluding clade 2) is included.
