Ethephon-responsive genes expression pattern obtained by kinetics-based clustering analysis. Group I, cluster of genes with early and transient changes; group II, clusters of genes modified in their expression until 2 d after treatment; group III, cluster of genes with expression kinetics exhibiting late changes; group IV, cluster of genes with persistent changes during the whole abscission process. The + and − signs in bracket represent up- and down-regulated of genes, respectively, while 0 represents no change. The numbers on the right of bracket indicate the total numbers of genes in each cluster. All of these changes were based on a four-fold change criterion (log2 ratio) indicated by blue dotted line. Gray dotted line indicates the gene-expression levels and the average values of gene-expression level in clusters is shown by the red solid lines.
