| T1 |
0-104 |
Sentence |
denotes |
Expression of a gibberellin 2-oxidase gene around the shoot apex is related to phase transition in rice. |
| T2 |
105-226 |
Sentence |
denotes |
A major catabolic pathway for gibberellin (GA) is initiated by 2beta-hydroxylation, a reaction catalyzed by GA 2-oxidase. |
| T3 |
227-390 |
Sentence |
denotes |
We have isolated and characterized a cDNA, designated Oryza sativa GA 2-oxidase 1 (OsGA2ox1) from rice (Oryza sativa L. cv Nipponbare) that encodes a GA 2-oxidase. |
| T4 |
391-624 |
Sentence |
denotes |
The encoded protein, produced by heterologous expression in Escherichia coli, converted GA(1), GA(4), GA(9), GA(20), and GA(44) to the corresponding 2beta-hydroxylated products GA(8), GA(34), GA(51), GA(29), and GA(98), respectively. |
| T5 |
625-753 |
Sentence |
denotes |
Ectopic expression of the OsGA2ox1 cDNA in transgenic rice inhibited stem elongation and the development of reproductive organs. |
| T6 |
754-813 |
Sentence |
denotes |
These transgenic plants were deficient in endogenous GA(1). |
| T7 |
814-930 |
Sentence |
denotes |
These results indicate that OsGA2ox1 encodes a GA 2-oxidase, which is functional not only in vitro but also in vivo. |
| T8 |
931-1006 |
Sentence |
denotes |
OsGA2ox1 was expressed in shoot apex and roots but not in leaves and stems. |
| T9 |
1007-1145 |
Sentence |
denotes |
In situ hybridization analysis revealed that OsGA2ox1 mRNA was localized in a ring at the basal region of leaf primordia and young leaves. |
| T10 |
1146-1288 |
Sentence |
denotes |
This ring-shaped expression around the shoot apex was drastically decreased after the phase transition from vegetative to reproductive growth. |
| T11 |
1289-1414 |
Sentence |
denotes |
It was absent in the floral meristem, but it was still present in the lateral meristem that remained in the vegetative phase. |
| T12 |
1415-1631 |
Sentence |
denotes |
These observations suggest that OsGA2ox1 controls the level of bioactive GAs in the shoot apical meristem; therefore, reduction in its expression may contribute to the early development of the inflorescence meristem. |
