Safflower CtFT genes orchestrating flowering time and flavonoid biosynthesis.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSafflower thrives in dry environments but faces difficulties with flowering in wet and rainy summers. Flavonoids play a role in flower development and can potentially alleviate these challenges. Furthermore, the FLOWERING LOCUS T (FT) family of phosphatidylethanolamine-binding protein (PEBP) genes play a crucial role in the photoperiodic flowering pathway. However, their direct impact on flowering and flavonoid biosynthesis under different light duration is elusive.
resultsUtilizing the genome sequencing of Safflower (Jihong NO.1), the current study identifies three specific genes (CtFT1, CtFT2, and CtFT3) that exhibit upregulation in response to long-day conditions. The overexpression of CtFT2, displayed an early, whereas CtFT1 and CtFT3 late flowering phenotype in Arabidopsis thaliana. Interestingly, the transient overexpression of CtFT1 in safflower leaves caused early flowering, while overexpressing CtFT2 and CtFT3 led to late flowering. Additionally, overexpressing CtFT3 in Arabidopsis and CtFT1, CtFT2, and CtFT3 in safflower leaves, significantly increased flavonoid synthesis.
conclusionsThese findings showed that overexpression of CtFT genes could affect the flowering time and significantly increase the flavonoid content of safflower. The function of CtFT gene is different in safflower and Arabidopsis. This study provides valuable insights into the role of CtFT genes in flower formation and flavonoid synthesis in safflower, which may help in improving safflower breeding quality and its adaptability to diverse environmental conditions.
