Fanfan Y, Yougen C, Bingjing L, Defang G, Hua W, Dongliang W.2018. Identification of WD40 gene family in Prunus mume and its expression level under light illumination. PeerJ Preprints6:e27106v1https://doi.org/10.7287/peerj.preprints.27106v1
The WD40 gene family in Prunusmume was identified by bioinformatics analysis., The evolution and function of WD40 gene family were predicted by phylogenetic analysis, chromosome localization analysis, protein sequence analysis, exon-intron structure analysis. The results showed that the WD40 gene family contained 77 members, which were divided into 61 groups, and only 18 groups had more than one member. When the plum plants were treated with different density of light illumination, the content of anthocyanin in plants was increased with the illumination enhancement, qRT-PCR analyses revealed that the expression of 27 WD40 genes showed the same expression trend. The results of this study can provide useful information for further studying the function of WD40 genes in Prunusmume.
This is a submission to PeerJ for review.
