Genome-wide identification and expression pattern analysis under drought stress of PHD family genes in alfalfa (Medicago sativa).

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
backgroundAlfalfa (Medicago sativa) is a perennial high-quality legume forage widely cultivated worldwide, but drought stress severely restrict its growth and development. Plant homeodomain finger (PHD) family genes are a type of zinc finger transcription factors widely distributed in eukaryotes. They act as histone code identifier to regulate the expression of downstream genes and play important biological roles in plant growth, development, and stress response. However, information about the PHD family genes in alfalfa remains limited at present.
resultsWe identified 56 MsPHD genes containing 67 PHD domains in the alfalfa, and these genes were unevenly distributed on 8 chromosomes of alfalfa. There are 9 pairs of gene fragment duplicates in the MsPHD family. The 56 MsPHD genes are evolutionarily divided into 14 subgroups. There are differences in the conservative motifs and gene structure composition patterns of MsPHD among different subgroups. In addition, we identified 11 MsPHD genes related to drought stress, and their promoter regions all contained elements related to stress response. Quantitative Real-time PCR (QRT-PCR) further verified that the expression levels of these 11 MsPHD genes were significantly up-regulated in both roots and leaves, with MsPHD9 showing the highest upregulation. 57.14% of MsPHD proteins were predicted to be located in the nucleus, and the co-localization analysis of MsPHD9 protein confirmed that it was primarily located in the nucleus.
conclusionsThe identification of alfalfa PHD family genes not only provides important genetic resources for in-depth analysis of the molecular mechanism of alfalfa drought resistance, but also lays a foundation for creating new germplasm of alfalfa with strong drought resistance through genetic engineering technology.
