Transcript profiling of carotenoid/apocarotenoid biosynthesis genes during corm development of saffron (Crocus sativus L.).

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
The dried stigmas of saffron constitute the world's costliest spice. Saffron has many therapeutic applications due to the presence of apocarotenoids. The latter are synthesized at different stages of development, and the biosynthetic pathway involves several genes encoding different enzymes. In order to understand the differential expression of various genes of the pathway, eight distinct developmental stages (S1-early to S8-late) were identified. The corms were assorted into three groups (I, II, and III) based on corm weight. Expression profiles of 12 carotenoid/apocarotenoid genes were studied. The expression of all genes was minimum/least in groups I and II corms during bud development. Lowest expression of carotenogenic genes (CsPSY, CsPDS, CsZDS, CsCRTISO, CsLYC-β1, CsLYC-ε, CsBCH2, and CsNCED) was observed during early stages (S1-S3) of corm growth (dormant period). In group III corms, increased expression of apocarotenoid genes (CsZCO, CsCCD2, CsUGT, and CsALDH) was observed during S4 to S8 stages (reproductive period, floral differentiation). Besides, expression profiles of genes in apical and axillary buds were also examined. Of all the genes studied, apocarotenoid biosynthesis genes (CsBCH2, CsZCO, CsCCD2, CsALDH, and CsUGT) were found to be upregulated in apical bud than in the axillary bud. The results indicated that interaction of phytohormones and sugars, mother corm reserves and the influence of internal and external factors may be contributing to the growth of saffron corm/bud. The study has laid a foundation for further research on the molecular mechanisms underlying bud dormancy/growth in saffron.
