Durum wheat nuclear factor Y (NF-Y) a subfamily: structure, phylogeny, and expression analysis in response to hormones and abiotic stresses.

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
Nuclear factor-Y (NF-Y) transcription factors are heterotrimeric complexes that are widely distributed in eukaryotes and play essential roles in many biological processes. Although NF-YA proteins have been characterized in numerous plants, their contribution to the response of durum wheat (Triticum turgidum ssp. durum) to environmental factors has not been reported. Thus, this study was aimed at identification and characterization of Triticum turgidum TtNF-YA family members through genome-wide analysis. Twelve NF-YA genes were discovered in Triticum turgidum. Discovered genes were distributed across eight chromosomes, while their encoded proteins were localized in cell nucleus. Structure and motif pattern analyses revealed that the TtNF-YA genes were relatively conserved. The expression of TtNF-YAs genes was significantly induced by several stressors and their expression profiles differed in various tissues and at various development stages. Notably, TtNF-YA2 A-1 and TtNF-YA2B-1 exhibited the greatest increase in response to Polyethylene glycol, while TtNF-YA4 A and TtNF-YA4B-1 showed the highest increase under salt stress. Additionally, TtNF-YA5B-1 and TtNF-YA6 A-1 displayed pronounced upregulation when exposed to exogenous Abscisic acid, suggesting that TtNF-YA are involved in a series of cellular and developmental events. This finding was corroborated by the recognition of several cis-regulatory elements in the TtNF-YAs promoter region, associated with the applied treatments. Overexpression of TtNF-YA2 A-1, TtNF-YA2B-1, TtNF-YA4 A, TtNF-YA4 A-1, TtNF-YA4B-1, and TtNF-YA5 A-2 genes in Saccharomyces cerevisiae showed that these genes increase cell tolerance to multiple stresses. Our results will facilitate subsequent functional analysis of TtNF-YAs genes, which emerge as promising targets for genetic engineering for increasing wheat tolerance to multiple stresses.
