J Mol Microbiol Biotechnol
. 2008 Aug;
15(2-3):212-9.
PMID: 18685273
Phytoremediation is the use of plants to remove xenobiotic compounds from the environment. Plants have the inherent ability to detoxify xenobiotic pollutants, but they are generally poor at degrading them....

Mitsuhara I, Iwai T, Seo S, Yanagawa Y, Kawahigasi H, Hirose S, et al.
Mol Genet Genomics
. 2008 Feb;
279(4):415-27.
PMID: 18247056
Pathogenesis-related (PR) proteins have been used as markers of plant defense responses, and are classified into 17 families. However, precise information on the majority members in specific PR families is...

J Agric Food Chem
. 2008 Jan;
56(4):1259-63.
PMID: 18217708
CYP72A21, a rice cytochrome P450 gene, is induced by chloroacetamide herbicides. OSB2, a rice myc-type transcription factor, induces anthocyanin accumulation in rice leaves. To produce plants for biomonitoring by color...

Kawahigashi H, Hirose S, Iwai T, Ohashi Y, Sakamoto W, Maekawa M, et al.
J Agric Food Chem
. 2007 Jan;
55(4):1241-7.
PMID: 17253710
Anthocyanin pigmentation provides an excellent system with which to study the regulation of gene expression in higher plants. In this study, OsPR1.1 promoter was isolated and the promoter activity was...

Kawahigashi H, Hirose S, Ohkawa H, Ohkawa Y
Biotechnol Adv
. 2006 Dec;
25(1):75-84.
PMID: 17156966
Cytochrome P450 monooxygenases (P450s) metabolize herbicides to produce mainly non-phytotoxic metabolites. Although rice plants endogenously express multiple P450 enzymes, transgenic plants expressing other P450 isoforms might show improved herbicide resistance...

Kawahigashi H, Hirose S, Ohkawa H, Ohkawa Y
J Agric Food Chem
. 2006 Apr;
54(8):2985-91.
PMID: 16608219
This study evaluated the expression of human cytochrome P450 genes CYP1A1, CYP2B6, and CYP2C19 in rice plants (Oryza sativa cv. Nipponbare) introduced using the plasmid pIKBACH. The transgenic rice plants...

Kawahigashi H, Hirose S, Ozawa K, Ido Y, Kojima M, Ohkawa H, et al.
Transgenic Res
. 2005 Nov;
14(6):907-17.
PMID: 16315095
We introduced two novel types of pig (Sus scrofa) cytochrome P450, CYP2B22 and CYP2C49, into rice plants (Oryza sativa L. cv. 'Nipponbare') to produce herbicide-tolerant plants and to confirm the...

J Agric Food Chem
. 2005 Nov;
53(23):9155-60.
PMID: 16277416
We introduced the human cytochrome P450 gene CYP2B6 into rice plants (Oryza sativa L. cv. Nipponbare), and the CYP2B6-expressing rice plants became more tolerant to various herbicides than nontransgenic Nipponbare...

J Agric Food Chem
. 2005 Oct;
53(22):8557-64.
PMID: 16248553
The human cytochrome P450 CYP1A1 gene was introduced into rice plants (Oryza sativa cv. Nipponbare). One-month-old CYP1A1 plants grown in soil clearly showed a healthy growth and tolerance to 8.8...

J Agric Food Chem
. 2005 Apr;
53(9):3461-7.
PMID: 15853388
The human gene for CYP2B6, a cytochrome P450 monooxygenase that inactivates xenobiotic chemicals, was introduced into Oryza sativa cv. Nipponbare by Agrobacterium-mediated transformation. At germination, R(1) seeds of transgenic rice...
