“…There are four major pigments in plants: anthocyanins, betalains, carotenoids, and chlorophyll. Among them, anthocyanins, carotenoids, and chlorophyll are implicated in anthurium spathe color, and their concentrations and ratios define the spathe color and its intensity ( Lin et al., 2022 ). Betalains are restricted to the core Caryophyllales and do not occur in other plants including anthurium ( Timoneda et al., 2019 ).…”

“…Previous studies of anthuriums have been largely focused on specific gene regulations in red colored spathes (Li et al., 2016, Li et al., 2019 ; Lin et al., 2022 ), but there have been no reports on key genes in regulation of white and green colorations. Additionally, there has been no information about the interaction between TFs and structure genes in regulation of these two colors.…”

Modern anthuriums, Anthurium andraeanum (Hort.) are among the most popular flowering plants and widely used for interior decoration. Their popularity is largely attributed to the exotic spathes with different colors. Previous studies have reported color development in red spathe cultivars, but limited information is available on key genes regulating white and green colored spathes. This study analyzed anthocyanin, chlorophyll, and carotenoid contents as well as transcript differences in spathes of eight cultivars that differed in spathe colors ranging from red to white and green. Results showed that increased expression of a transcription factor AaMYB2 was associated with elevated levels of anthocyanin in spathes, but decreased expression of AaMYB2 and increased expression of AaLAR (leucoanthocyanidin reductase) and AaANR (anthocyanidin reductase) were accompanied with the accumulation of colorless proanthocyanidin, thus the white spathe. As to the green colored spathe, chlorophyll content in the green spathe cultivar was substantially higher than the other cultivars. Correspondingly, transcripts of chlorophyll biosynthesis-related genes AaHemB (porphobilinogen synthase) and AaPor (protochlorophyllide oxidoreductase) were highly upregulated but almost undetectable in white and red spathes. The increased expression of AaHemB and AaPor was correlated with the expression of transcription factor AaMYB124. Subsequently, qRT-PCR analysis confirmed their expression levels in nine additional cultivars with red, white, and green spathes. A working model for the formation of white and green spathes was proposed. White colored spathes are likely due to the decreased expression of AaMYB2 which results in increased expression of AaLAR and AaANR, and the green spathes are attributed to AaMYB124 enhanced expression of AaHemB and AaPor. Further research is warranted to test this working model.

Hybridization is considered an important mode of species evolution, but the genetic evolutionary process of Anthurium andraeanum hybridization is still poorly characterized. In order to provide the molecular and morphological basis for phylogenetic analysis in A. andraeanum hybridization, we analyzed the morphological, nuclear genomic, and chloroplast genomic data of five A. andraeanum cultivars and explored the correlations between different traits and nuclear and chloroplast genome characteristics. A. andraeanum hybrid 1 is an A. andraeanum ‘Baron’ (♀) × A. andraeanum ‘Spice’ (♂) cross, and A. andraeanum hybrid 2 is an A. andraeanum ‘Cheers’ (♀) × A. andraeanum hybrid 1 (♂) cross. The A. andraeanum hybrids reflected their parents’ heterozygous features in their morphologies, nuclear genomes, and chloroplast genomes. The morphological traits in the F1 generation were widely separated, showing continuous variation. Based on cluster analysis, the five A. andraeanum cultivars could be divided into two groups. The ISSR analysis results were highly correlated with the spathe color. Among the five A. andraeanum cultivars, the composition and structure features of chloroplast genomes were completely the same or highly similar, respectively. Phylogenetic analysis based on complete chloroplast genome data showed that the genetic stability of the chloroplast is high in A. andraeanum, manifested as uniparental maternal inheritance, where the chloroplast genome composition and structural features of hybrids are highly similar to those of the maternal parent.
