Other claims from this paper (8)
- Observation The tdd1 mutant shows dwarfing, narrow leaves and short roots.
- Observation The tdd1 mutant develops abnormal flowers.
- Observation TDD1 encodes a protein homologous to anthranilate synthase beta-subunit.
- Intervention effect Trp feeding rescued the mutant phenotypes.
- Intervention effect Moderate expression of OsYUCCA1 rescued plant height and root length.
- Mechanism The abnormal phenotypes of tdd1 are caused predominantly by Trp and IAA deficiency.
- Observation In tdd1 embryos, the expression patterns of OSH1 and OsSCR are identical to those in wild type.
- Observation TDD1-uidA and DR5-uidA expression overlapped at many sites in wild type but was lacking in tdd1.
