e0“wild type and ABA-deficient tomatoes were subjected to short-term (24 h) soil waterlogging”
e3“Waterlogging reduced the ABA levels in the roots while inducing PYR/PYL/RCAR ABA receptors and ABA-dependent transcription factor transcripts, of which induction was less pronounced in the ABA-deficient genotype”

Other claims from this paper (13)
- Intervention effect Soil waterlogging reduced gas exchange in wild-type tomato but not in ABA-deficient plants.
- Observation ABA-deficient tomato plants had higher E and gs than wild type.
- Intervention effect Transcript and metabolite alterations caused by waterlogging were more intense in waterlogged tissues, with genotype-specific variations.
- Intervention effect Waterlogging induced PYR/PYL/RCAR ABA receptors and ABA-dependent transcription factor transcripts in tomato.
- Intervention effect The waterlogging induction of ABA-dependent transcription factor transcripts was less pronounced in the ABA-deficient genotype than in wild type.
- Intervention effect Ethylene/O2-dependent genetic responses (ERFVIIs, anoxia survival and N-degron genes) were induced in hypoxic tissues independently of genotype.
- Intervention effect Genes encoding a nitrate reductase and a phytoglobin were induced in waterlogged tomato tissues.
- Intervention effect The waterlogging induction of nitrate reductase and phytoglobin genes was to a lower extent in ABA-deficient tomato than in wild type.
- Intervention effect Flooding-induced accumulation of Ala was enhanced in ABA-deficient tomato lines.
- Observation Glu and Asp accumulated differentially in both hypoxic and aerated tomato tissues.
- Mechanism Glu and Asp are likely sources of oxaloacetate that feed the TCA cycle in waterlogged tomato tissues.
- Mechanism Promoter analysis suggests that oxaloacetate production from Asp, energy processes and lignification are likely under ABA regulation in tomato.
- Mechanism ABA depletion in waterlogged tomato tissues acts as a positive signal that induces genetic and metabolic responses to soil flooding.
