| T1 |
0-123 |
Sentence |
denotes |
Sekiguchi lesion gene encodes a cytochrome P450 monooxygenase that catalyzes conversion of tryptamine to serotonin in rice. |
| T2 |
124-244 |
Sentence |
denotes |
Serotonin is a well known neurotransmitter in mammals and plays an important role in various mental functions in humans. |
| T3 |
245-332 |
Sentence |
denotes |
In plants, the serotonin biosynthesis pathway and its function are not well understood. |
| T4 |
333-444 |
Sentence |
denotes |
The rice sekiguchi lesion (sl) mutants accumulate tryptamine, a candidate substrate for serotonin biosynthesis. |
| T5 |
445-566 |
Sentence |
denotes |
We isolated the SL gene by map-based cloning and found that it encodes CYP71P1 in a cytochrome P450 monooxygenase family. |
| T6 |
567-699 |
Sentence |
denotes |
A recombinant SL protein exhibited tryptamine 5-hydroxylase enzyme activity and catalyzed the conversion of tryptamine to serotonin. |
| T7 |
700-759 |
Sentence |
denotes |
This pathway is novel and has not been reported in mammals. |
| T8 |
760-923 |
Sentence |
denotes |
Expression of SL was induced by the N-acetylchitooligosaccharide (chitin) elicitor and by infection with Magnaporthe grisea, a causal agent for rice blast disease. |
| T9 |
924-1088 |
Sentence |
denotes |
Exogenously applied serotonin induced defense gene expression and cell death in rice suspension cultures and increased resistance to rice blast infection in plants. |
| T10 |
1089-1246 |
Sentence |
denotes |
We also found that serotonin-induced defense gene expression is mediated by the RacGTPase pathway and by the G alpha subunit of the heterotrimeric G protein. |
| T11 |
1247-1332 |
Sentence |
denotes |
These results suggest that serotonin plays an important role in rice innate immunity. |
