Other claims from this paper (14)
- Intervention effect GA biosynthesis inhibitors decreased tomato fruit growth.
- Intervention effect GA(3) application reversed the inhibitor effects on tomato fruit growth and set.
- Intervention effect LAB 198999 reduced GA(1) and GA(8) content in pollinated tomato fruits.
- Intervention effect LAB 198999 increased precursor GA(53), GA(44), and GA(19) content in pollinated tomato fruits.
- Intervention effect LAB 198999 increased GA(20) precursor content in pollinated tomato fruits.
- Intervention effect GA(3), GA(1), GA(4), and GA(20) induced parthenocarpic development of unpollinated tomato ovaries, with GA(3) strongest.
- Intervention effect GA(19) did not induce parthenocarpic development of unpollinated tomato ovaries.
- Intervention effect Pollination increased transcripts of SlGA20ox1, -2, and -3 and SlCPS in tomato fruits.
- Intervention effect Pollination did not increase SlGA3ox1 and -2 transcripts in tomato fruits.
- Method / resource Five tomato GA 2-oxidase cDNA clones were isolated and characterized.
- Intervention effect Early after pollination, tomato SlGA2ox transcript levels did not decrease.
- Intervention effect Later after pollination, transcripts of all five tomato SlGA2ox genes decreased, especially SlGA2ox2.
- Mechanism The authors concluded that pollination mediates tomato fruit set through GA biosynthesis up-regulation of GA20ox.
- Observation Phylogenetic reconstruction found three tomato GA2ox gene subfamilies and established positions for five genes.
