SOTA clustering showing the expression profiles of ethylene- and water-deficit stress-induced leaf abscission. a SOTA clustering identified six AP2/ERF gene expression clusters among the six leaf abscission time points (114 and 103 AP2/ERF genes for ethylene- and water-deficit stress-induced leaf abscission, respectively). The signals are indicated using a red-green colour scale, where red and green represent increased and reduced expression, respectively. b Ethylene signalling GO annotation enrichment of AP2/ERF genes expressed during both ethylene and water-deficit stress treatments among the six SOTA clusters
