General statistics

Below you can find a global statistical analysis which summarizes our microarrays results.
General_expression_stats_fig_small
(A) Statistical analysis of the microarray data indicates that approximately half of the genome is significantly expressed in the gut and in each gut region (3 Affymetrix present call\ s for 3 chips).
(B) This figures indicates the proportion of gene enriched only in one region. 10% of the genes were enriched in only one region and down-regulated in other regions are considered to \ have a region specific expression.
(C) 34% of the genes is differentially regulated in distinct gut regions by at least 2 fold, and up to 53% by at least 1.5 fold.
(D) These histograms show the percentage of gene enriched in on region compared to the entire gut. The crop and the hindgut show a high number of regulated genes compared to the midgu\ t indicating a dichotomy in gene expression between the ectodermic (crop & hindgut) and endodermic (midgut) section of the gut.
