Arabidopsis CYP707As Encode (+)-Abscisic Acid 8′-Hydroxylase, a Key Enzyme in the Oxidative Catabolism of Abscisic Acid1
TLDR
It is established that the CYP707A family plays a key role in regulating the ABA level through the 8′-hydroxylation of (+)-ABA. Expand
Erect leaves caused by brassinosteroid deficiency increase biomass production and grain yield in rice
TLDR
It is shown that the erect leaf phenotype of a rice brassinosteroid–deficient mutant, osdwarf4-1, is associated with enhanced grain yields under conditions of dense planting, even without extra fertilizer, suggesting that regulated genetic modulation of brassinosterone biosynthesis can improve crops without the negative environmental effects of fertilizers.

CYP716A subfamily members are multifunctional oxidases in triterpenoid biosynthesis.
TLDR
A strong correlation is found between CYP716A12 and β-amyrin synthase (bAS), which encodes the enzyme responsible for the initial cyclization of 2,3-oxidosqualene to β-Amyrin (the basic structural backbone of most triterpenoid saponins), which indicates the highly conserved functionality of the CYP 716A subfamily among plants.

Licorice β-amyrin 11-oxidase, a cytochrome P450 with a key role in the biosynthesis of the triterpene sweetener glycyrrhizin
TLDR
The successful identification of CYP88D6, a cytochrome P450 monooxygenase (P450) gene, as a glycyrrhizin-biosynthetic gene, by transcript profiling-based selection from a collection of licorice expressed sequence tags is reported, suggesting a role for CYP 88D6 as a β-amyrin 11-oxidase in the glycy rhoizin pathway.

Scopoletin is biosynthesized via ortho-hydroxylation of feruloyl CoA by a 2-oxoglutarate-dependent dioxygenase in Arabidopsis thaliana.
TLDR
Results indicate that Fe(II)- and 2-oxoglutarate-dependent dioxygenase is the pivotal enzyme in the ortho-hydroxylation of feruloyl CoA in scopoletin biosynthesis. Expand
Evolution and diversity of the 2-oxoglutarate-dependent dioxygenase superfamily in plants.
TLDR
The vast majority of 2OGDs from land plants were classified into the DOXC class, but only seven from Chlamydomonas, suggesting that this class has diversified during land plant evolution, partly responsible for the diversity and complexity of specialized metabolites in land plants. Expand
Isolation of a cDNA and a Genomic Clone Encoding Cinnamate 4-Hydroxylase from Arabidopsis and Its Expression Manner in Planta
TLDR
C4H (CYP73A5) expression was apparently coordinated in Arabidopsis with both PAL1 and 4CL in response to light and wounding, and the C4H expression patterns exhibited no significant coordination with those of PAL2 and PAL3. Expand
Two isoforms of NADPH:cytochrome P450 reductase in Arabidopsis thaliana. Gene structure, heterologous expression in insect cells, and differential regulation.
TLDR
The results suggest the possibility that AR2 transcription may be functionally linked to the induced levels of phenylpropanoid pathway enzymes. Expand
Sekiguchi Lesion Gene Encodes a Cytochrome P450 Monooxygenase That Catalyzes Conversion of Tryptamine to Serotonin in Rice*
TLDR
The results suggest that serotonin plays an important role in rice innate immunity and that serotonin-induced defense gene expression is mediated by the RacGTPase pathway and by the Gα subunit of the heterotrimeric G protein. Expand
Highly sensitive and high-throughput analysis of plant hormones using MS-probe modification and liquid chromatography-tandem mass spectrometry: an application for hormone profiling in Oryza sativa.
TLDR
Application of this method to plant hormone profiling enabled us to draw organ distribution maps of hormone species in rice and also to identify interactions among the four major hormones in the rice gibberellin signaling mutants. Expand
