Flavonoid Accumulation

Anthocyanins (a subclass of flavonoids) and flavonoids are crucial determinants of flower color and substances of pharmacological efficacy, respectively, in chrysanthemum. However, metabolic and transcriptomic profiling regarding flavonoid accumulation has not been performed simultaneously, thus the understanding of mechanisms gained has been limited. We performed HPLC-DAD-ESI-MS (high-performance liquid chromatography coupled with photodiode array detection and electrospray ionization mass spectrometry) and transcriptome analyses using “ARTI-Dark Chocolate” (AD), which is a chrysanthemum mutant cultivar producing dark-purple ray florets, and the parental cultivar “Noble Wine” for metabolic characterization and elucidation of the genetic mechanism determining flavonoid content. Among 26 phenolic compounds identified, three cyanidins and eight other flavonoids were detected only in AD. The total amounts of diverse flavonoids were 8.0 to 10.3 times higher in AD. Transcriptome analysis showed that genes in the flavonoid biosynthetic pathway were not up-regulated in AD at the early flower stage, implying that the transcriptional regulation of the pathway did not cause flavonoid accumulation. However, genes encoding post-translational regulation-related proteins, especially F-box genes in the mutated gene, were enriched among down-regulated genes in AD. From the combination of metabolic and transcriptomic data, we suggest that the suppression of post-translational regulation is a possible mechanism for flavonoid accumulation in AD. These results will contribute to research on the regulation and manipulation of flavonoid biosynthesis in chrysanthemum.

Chrysanthemum Morifolium Ramat

Dihydroflavonol 4-reductase (DFR) catalyzes a committed step in anthocyanin and proanthocyanidin biosynthesis by reducing dihydroflavonols to leucoanthocyanidins. However, the role of this enzyme in determining flower color in the economically important crop chrysanthemum (Chrysanthemum morifolium Ramat.) is unknown. Here, we isolated cDNAs encoding DFR from two chrysanthemum cultivars, the white-flowered chrysanthemum “OhBlang” (CmDFR-OB) and the red-flowered chrysanthemum “RedMarble” (CmDFR-RM) and identified variations in the C-terminus between the two sequences. An enzyme assay using recombinant proteins revealed that both enzymes catalyzed the reduction of dihydroflavonol substrates, but CmDFR-OB showed significantly reduced DFR activity for dihydrokaempferol (DHK) substrate as compared with CmDFR-RM. Transcript levels of anthocyanin biosynthetic genes were consistent with the anthocyanin contents at different flower developmental stages of both cultivars. The inplanta complementation assay, using Arabidopsis thaliana dfr mutant (tt3-1), revealed that CmDFR-RM, but not CmDFR-OB, transgenes restored defective anthocyanin biosynthesis of this mutant at the seedling stage, as well as proanthocyanidin biosynthesis in the seed. The difference in the flower color of two chrysanthemums can be explained by the C-terminal variation of CmDFR combined with the loss of CmF3H expression during flower development.

Meningkatnya minat masyarakat terhadap tanaman krisan tidak diimbangi dengan meningkatnya produksi tanaman ini. Salah satu kendala dalam pengembangan produksi benih krisan dari hasil perbanyakan dengan setek adalah perakaran yang lemah. Perbanyakan secara vegetatif melalui setek permasalahan pokoknya adalah pada pembentukan akar. Penelitian dilaksanakan dari bulan November 2018 sampai bulan Januari 2019. Penelitian dilaksanakan di Greenhouse Kebun Percobaan Balai Penelitian Tanaman Hias Jl. Raya Ciherang, Segunung, Pacet, Cianjur, Jawa Barat 43252. Penelitian menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor. Faktor pertama jenis varietas krisan pot yaitu Varietas Avanthe (V1), Varietas Prita (V2) dan Varietas Naura (V3).dan faktor kedua jenis ZPT yaitu Kontrol (Z1), Rootone F (Z2) dan PGPR (Z3). Interakasi antara aplikasi jenis ZPT dan setek 3 varietas krisan pot pada pengamatan 21 HST memberikan pengaruh tidak berbeda nyata terhadap semua parameter, kecuali pada parameter tinggi tanaman dan jumlah daun. Interaksi terbaik ditunjukkan oleh perlakuan penggunaan Rootone F pada Varietas Avanthe.
