Fig. 1: RhHB1 expression in stressed rose petals.

a RhHB1 transcript levels in rose petals under dehydration. RhUBI1 was tested as an internal control. b RhHB1 expression levels after exogenous hormone treatments. 6-BA, 100 µM 6-benzylaminopurine; SA, 100 µM salicylic acid; JA, 100 µM methyl jasmonate. Rose flowers were treated at opening stage 2. All the values are the means ± SDs of five biological replicates
