- Key message
- Treatment of aerobic seedlings with ethylene and its precursor, 1-aminocyclopropane-1-carboxylate (ACC), rapidly induced the expression of OsABA8ox1, but the ethylene treatment did not strongly affect the expression of ABA biosynthetic genes
- Moreover, pre-treatment with 1-methylcyclopropene (1-MCP), a potent inhibitor of ethylene action, partially suppressed induction of OsABA8ox1 expression under submergence
- Together, these results indicate that the rapid decrease in ABA levels in submerged rice shoots is controlled partly by ethylene-induced expression of OsABA8ox1 and partly by ethylene-independent suppression of genes involved in the biosynthesis of ABA
- Ethylene promotes submergence-induced expression of OsABA8ox1, a gene that encodes ABA 8’-hydroxylase in rice
- The oxidation of ABA to PA is catalyzed by ABA 8’-hydroxylase, which is possibly encoded by three genes (OsABA8ox1, -2 and -3) in rice
- The ABA 8’-hydroxylase activity was confirmed in microsomes from yeast expressing OsABA8ox1
- The ABA level was found to be negatively correlated with OsABA8ox1 expression under ACC or 1-MCP treatment
- The mRNA level of OsABA8ox1, but not the mRNA levels of other OsABA8ox genes, increased dramatically within 1 h after submergence

- OsABA8ox1, OsNCED1~OsCCD4a, Phosphorylation of D-allose by hexokinase involved in regulation of OsABF1 expression for growth inhibition in Oryza sativa L, In this study, we discovered that D-allose induced expression of ABA-related genes including OsNCED1-3 and OsABA8ox1-3 in rice
- OsABA8ox1, OsNAC2~OsTIL1~OMTN2~OsORE1, A Rice NAC Transcription Factor Promotes Leaf Senescence via ABA Biosynthesis., Moreover, ectopic expression of OsNAC2 leads to an increase in ABA levels via directly upregulating expression of ABA biosynthetic genes (OsNCED3 and OsZEP1) as well as downregulating the ABA catabolic gene (OsABA8ox1)
- OsABA8ox1, OsbHLH035~OsbHLH35, The transcription factor OsbHLH035 mediates seed germination and enables seedling recovery from salt stress through ABA-dependent and ABA-independent pathways, respectively., In parallel, abscisic acid (ABA) contents are over-accumulated, and the expression of the ABA biosynthetic genes OsABA2 and OsAAO3 is upregulated; furthermore, compared with that in wild-type (WT) seedlings, the salt-induced expression of OsABA8ox1, an ABA catabolic gene, in germinating Osbhlh035 mutant seeds is downregulated
- OsABA8ox1, OsNAC2~OsTIL1~OMTN2~OsORE1, OsNAC2 Is Involved in Multiple Hormonal Pathways to Mediate Germination of Rice Seeds and Establishment of Seedling, Moreover, OsNAC2 delays the germination of seeds and coleoptile growth through the ABA pathway instead of the ethylene and GA pathway, by targeting the promoters of OsNCED3, OsZEP1, and OsABA8ox1
- OsABA8ox1, OsWRKY53, OsWRKY53 Promotes Abscisic Acid Accumulation to Accelerate Leaf Senescence and Inhibit Seed Germination by Downregulating Abscisic Acid Catabolic Genes in Rice., Chromatin immunoprecipitation and protoplast transient assays revealed that OsWRKY53 directly bound to the promoters of OsABA8ox1 and OsABA8ox2 to repress their transcription, resulting in elevated endogenous ABA contents that promoted premature leaf senescence in the OsWRKY53-oe plants
- OsABA8ox1, OsNR1, NLP2-NR Module Associated NO Is Involved in Regulating Seed Germination in Rice under Salt Stress., Transient trans-activation assays further revealed NLP2 can significantly activate the expression of OsABA8ox1 and OsNR1, suggesting that NLP2 activates expression of ABA catabolism gene directly or indirectly via NR-associated NO

- OsABA8ox1, OsNF-YA3, OsNF-YA3 regulates plant growth and osmotic stress tolerance by interacting with SLR1 and SAPK9 in rice., OsNF-YA3 reduces ABA levels by transcriptionally regulating ABA catabolic genes OsABA8ox1 and OsABA8ox3 by binding to their promoters
- OsABA8ox1, OsLTPL23, Rice lipid transfer protein, OsLTPL23, controls seed germination by regulating starch-sugar conversion and ABA homeostasis., Transcript profiles in the germinating seeds exhibited that the abscisic acid (ABA)-responsive genes, OsABI3 and OsABI5, and biosynthesis genes, OsNCED1, OsNCED2, OsNCED3 and OsNCED4, are obviously upregulated in the osltpl23 mutants compared to NIP plants, conversely, ABA metabolism genes OsABA8ox1, OsABA8ox2 and OsABA8ox3 are stepwise decreased
