ABA-dependent signaling in hpAtPARP2 plants. (A) Expression analysis of cluster IV and V transcripts in response to various environmental stimuli. Hierarchical average linkage clustering of the response profiles of 84 transcripts to various abiotic stress conditions and treatment with plant hormones is presented. Data were obtained with Genevestigator (27). MJ, methyl jasmonate; ACC, 1-aminocyclopropane-1-carboxylic acid; GA3, gibberellic acid 3; ABA, abscisic acid; BL, brassinolide; IAA, indole-3-acetic acid. (B) Quantification of the endogenous ABA content in wild-type (○) and hpAtPARP2 (●) plants exposed to 0, 2, 4, and 6 h of HL. Initial levels of ABA in wild-type (white bar) and hpAtPARP2 (black bar) plants are enlarged. Results are expressed as ng ABA per g of fresh weight (FW) and represent the mean ± SE of two repeat experiments.
