Supplemental Data

Files in this Data Supplement:

• Supplemental Figure 1 - Figure s1: BABA-induced resistance against P. syringae pv. tomato DC3000 in wild-type plants (Col-0) and mutants s-111 and s-765, which both contain a T-DNA insertion in the second exon of the IBS1 gene. Resistance was quantified by determining the level of bacterial growth (A) and the level of disease symptoms (B) at 3 days after infection. Photos (C) were taken at 4 days after inoculation with P. syringae. For details see legend to Figure 3.
• Supplemental Figure 2 - Figure s2: BABA-induced resistance against H. parasitica strain WACO9 in wild-type plants (Col-0) and mutants s-111, s-765, s031432, npq2-1, and aba1-5. Mutants s-111 and s-765 have a T-DNA insertion in the IBS1 gene, whereas mutant s-031243 carries a T-DNA in the 5'-UTR of the AtSAC1b/IBS2 gene. Mutants npq2-1 and aba1-5 have EMS mutations in the ABA1/IBS3 gene. Disease severity (A) was quantified at 8 days after inoculation, and callose deposition (B) was quantified at 2 days after inoculation. For details see legend to Figure 5.
• Supplemental Figure 3 - Figure s3: BABA-induced tolerance to salt stress in wild-type plants (Col-0) and mutants s031432, npq2-1, and aba1-5. Mutant s031432 has a T-DNA insertion in the promoter region of the AtSAC1b/IBS2 gene, whereas npq2-1 and aba1-5 are mutated in the ABA1/IBS3 gene. For details see legend to Figure 6.
