Other claims from this paper (9)
- Mechanism The expansion, particularly in TFL1-like and Group 4 GRF genes, was likely caused by polyploidization and segmental duplication.
- Observation The flowering gene family members showed distinct tissue-specific expression patterns during lavender floral development.
- Intervention effect Heterologous overexpression of LaFT8 in Arabidopsis accelerated flowering in a dose-dependent manner.
- Intervention effect LaFT8 overexpression in Arabidopsis upregulated expression of AtSOC1, AtLFY and AtAP1 by approximately 2- to 15-fold.
- Intervention effect LaTFL1-1 overexpression in Arabidopsis delayed flowering.
- Intervention effect LaTFL1-1 overexpression in Arabidopsis suppressed AtAP1 and AtSOC1 expression.
- Intervention effect No significant phenotypic changes were observed in Arabidopsis overexpressing LaFT4 or LaTFL1-3.
- Observation Protein interaction assays confirmed formation of a flowering activation complex between LaFT8, LaFD3 and LaGRFs.
- Mechanism LaTFL1-1 competes by binding LaFD3 with higher affinity, thereby inhibiting LaFT8 function.
