- Key message
- Further experiments indicated that the expression of OsABA8ox3, a key gene in ABA catabolism and encoding ABA 8’-hydroxylase in rice, was significantly increased during the first 6 h of imbibition, which was consistent with the decline of ABA content in the imbibed seeds
- Enzyme activity analysis indicated that OsABA8ox3 RNAi plants had higher superoxide dismutase (SOD) and catalase (CAT) activities and less malondialdehyde (MDA) content than those of wild type when the plants were exposed to dehydration treatment, indicating a better anti-oxidative stress capability and less membrane damage
- However, OsABA8ox3 RNAi lines showed significant improvement in drought stress tolerance while the overexpression seedlings were hypersensitive to drought stress when compared with wild type in terms of plant survival rates after 10 days of unwatering
- We therefore conclude that that OsABA8ox3 gene plays an important role in controlling ABA level and drought stress resistance in rice
- Expression of OsABA8ox3 was promptly induced by rehydration after PEG-mimic dehydration, a tendency opposite to the changes of ABA level
- LEA genes, were enhanced with higher transcript levels in OsABA8ox3 RNAi transgenic seedlings
- Connection
- OsABA8ox2~OsCYP707A6, OsABA8ox3, Glucose-induced delay of seed germination in rice is mediated by the suppression of ABA catabolism rather than an enhancement of ABA biosynthesis, Expression of OsABA8ox genes, especially OsABA8ox2 and OsABA8ox3, was sensitively suppressed in the presence of exogenously supplied glucose
- OsABA8ox3, OsHIPL1, OsHIPL1, a hedgehog-interacting protein-like 1 protein, increases seed vigour in rice., The higher levels of endogenous ABA were measured in germinating seeds of OsHIPL1 mutants and NIL-qsv3 line compared to IR26 plants, with two up-regulated ABA biosynthesis genes (OsZEP and OsNCED4) and one down-regulated ABA catabolism gene OsABA8ox3
- OsABA8ox1, OsABA8ox3, Improving pre-harvest sprouting resistance in rice by editing OsABA8ox using CRISPR/Cas9., There are three genes that encode ABA8' hydroxylase in rice, named OsABA8ox1, OsABA8ox2 and OsABA8ox3
- OsABA8ox2~OsCYP707A6, OsABA8ox3, Improving pre-harvest sprouting resistance in rice by editing OsABA8ox using CRISPR/Cas9., There are three genes that encode ABA8' hydroxylase in rice, named OsABA8ox1, OsABA8ox2 and OsABA8ox3
- OsABA8ox3, 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
- OsABA8ox3, 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
