Fig. 1. (A) Structure of the INCO gene in the wild-type and in
inco mutant alleles. Black boxes represent exons and white boxes are
introns. Triangles show the position of transposable elements (Tam) in four
mutant inco alleles. (B) Northern blot with mRNA isolated from
wild-type and inco inflorescences probed with INCO cDNA and
with ACTIN cDNA as loading control.
