Characterization and Expression Analysis of Phytoene Synthase from Bread Wheat (Triticum aestivum 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
Phytoene synthase (PSY) regulates the first committed step of the carotenoid biosynthetic pathway in plants. The present work reports identification and characterization of the three PSY genes (TaPSY1, TaPSY2 and TaPSY3) in wheat (Triticum aestivum L.). The TaPSY1, TaPSY2, and TaPSY3 genes consisted of three homoeologs on the long arm of group 7 chromosome (7L), short arm of group 5 chromosome (5S), and long arm of group 5 chromosome (5L), respectively in each subgenomes (A, B, and D) with a similarity range from 89% to 97%. The protein sequence analysis demonstrated that TaPSY1 and TaPSY3 retain most of conserved motifs for enzyme activity. Phylogenetic analysis of all TaPSY revealed an evolutionary relationship among PSY proteins of various monocot species. TaPSY derived from A and D subgenomes shared proximity to the PSY of Triticum urartu and Aegilops tauschii, respectively. The differential expression of TaPSY1, TaPSY2, and TaPSY3 in the various tissues, seed development stages, and stress treatments suggested their role in plant development, and stress condition. TaPSY3 showed higher expression in all tissues, followed by TaPSY1. The presence of multiple stress responsive cis-regulatory elements in promoter region of TaPSY3 correlated with the higher expression during drought and heat stresses has suggested their role in these conditions. The expression pattern of TaPSY3 was correlated with the accumulation of β-carotene in the seed developmental stages. Bacterial complementation assay has validated the functional activity of each TaPSY protein. Hence, TaPSY can be explored in developing genetically improved wheat crop.
