BMC Genomics(2021) 22:Page two ofBackground Leaf color is one of the most significant characteristics of ornamental plants, and plants with colored foliage were normally named “colored-leaf plants” [1, 2]. Some researchers have analyzed and determined systematically the pigments and physiological indexes with the leaves of coloredleaf plants [3, 4]. Outcome showed that the alter of leaf color is closely associated to the synthesis and accumulation of anthocyanins in leaves [5]. Anthocyanins are certainly one of the important secondary metabolites of plants and they typically have anti-cancer, anti-oxidation and antiatherosclerosis properties [6]. Anthocyanins confer orange, red, magenta, violet and blue plus the biosynthetic pathway leading to floral or pulp pigment accumulation had been properly characterized plus the genes encoding relevant enzymes and MAP3K8 MedChemExpress transcriptional components have been isolated [7, 8]. The molecular mechanisms of the anthocyanin biosynthesis pathway also happen to be comprehensively reported. Nevertheless, the majority of the researches primarily focused on f fruit color [9] and petal colour [102], and anthocyanin biosynthesis in colored-leaf plants has rarely been researched prior to this study. In recent years, some scholars have identified PAL, CHS, CHI, DFR, ANS, F3H, F3’H, F3’5’H [13, 14] as well as a couple of related regulatory genes for instance MYB, bHLH and WDR in color altering of colored-leaf plants [15, 16]. The procedure of anthocyanin synthesis and accumulation is fairly complicated, and is regulated by various enzymes and transcription components [17], also as being influenced by external environmental elements like light [18], water tension [19], and temperature [20]. As a result the mechanism of leaf colour transform in colored-leaf plants demands to be additional studied. Acer pseudosieboldianum is a little deciduous tree belonging to the Acer genus of the loved ones Aceraceae. Because of its attractive shape and brilliant leaves, it really is an usually used autumn leaf ornamental tree species [21]. Furthermore, it has high economic value, whose woods might be utilized for creating utensils and leaves can be applied as dyes [22]. Recently, some scholars have reported and studied the introduction, cultivation, and breeding of A. pseudosieboldianum [23, 24]. On the other hand the essential genes affecting leaf color transform have not been determined but, and relative information is comparatively scarce. This fact means that the molecular regulatory mechanisms related to leaf color formation wants additional study. In recent years, transcriptome high-throughput sequencing technologies has been broadly applied to study the mechanism of leaf color in various plants [25, 26]. In this study, de novo transcriptome sequencing assembly, annotation, and bioinformatic evaluation on leaves from A. pseudosieboldianum have been performed at distinctive colorchanging stages in autumn. The DEGs at various transformation stages were analyzed and validated. At final,combined this information with anthocyanin metabolism analysis information, some genes related to anthocyanin synthesis have been identified. This study supplies a theoretical basis for studying the molecular mechanism of le.
