“…Color indices and pH value measurements -The colors of the fresh petals were measured based on the Royal Horticultural Society Color Chart (RHSCC) with a CR-400 chroma meter (Konica Minolta, Tokyo, Japan). Flower color was described using two parameters, L * (lightness) and a * (ratio of red to green) (Li et al 2018). Ten sets of values were obtained and used to calculate means.…”

“…Anthocyanins are the most important floral pigments and contribute to the wide range of red to purple colors (Iwashina 2015). The anthocyanin biosynthesis pathway has been well described in many horticultural species, such as apples, roses and petunias (Peng and Moriguchi 2013;Liu et al 2015;Li et al 2018). This pathway involves a number of reactions that are catalyzed by various enzymes.…”

Malus hupehensis (Pamp.) Rehder is an indigenous wild crabapple tree from China that has received increased attention, due to its significant ornamental and economical values. The flowers change from red to white during development, a phenomenon that is prevalent within Malus genus. However, there are no reports on the phytochemical aspects of M. hupehensis flower. Here, we investigated the mechanism of color fading through biochemical and molecular analysis of M. hupehensis petals during development. Sixteen flavonoids were detected, and cyanidin-3-galactoside was the major anthocyanin in petals. The levels of most compounds initially increased and then decreased during flower development. The changing profile of total anthocyanins was consistent with the changes in floral color. Analysis of anthocyanin biosynthesis-related genes showed that the expression levels of PAL, CHS, CHI, DFR, FLS, ANS, UFGT, MYB10 and MYB12 were significantly higher at early stages than at later stages, similarly to the change in cyanidin-3-galactoside contents. MYB10 and MYB12 significantly positively correlated with CHS, CHI and DFR. There was a particularly strong positive correlation between MYB10 and ANS, and MYB12 was strongly positively correlated with LAR. Thus, MYB10 appeared to regulate mainly anthocyanin biosynthesis, and MYB12 could influence the expression of multiple structural genes in both the anthocyanin and flavanol pathways. By contrast, MYB6, bHLH33 and WD40 were significantly and positively correlated with one another but negatively correlated with the levels of many compounds and most structural genes, indicating that these three transcription factors could regulate together anthocyanin biosynthesis. Our results revealed the information about the temporal and spatial regulation of anthocyanin biosynthesis in M. hupehensis and provide the diverse flower color intensities and patterning in Chinese crabapple.

“…However, the drawbacks of wood, such as dimensional instability when exposed to wet conditions and biological degradation when exposed to decay fungi, limit its long-term utilization [6][7][8][9][10]. Although its biodegradable nature is beneficial, from the perspective of sustainable development wood still needs to be modified to obtain better durability when exposed to the above harsh environments [11][12][13][14][15]. The durability of wood with respect to deformation in water and biological degradation due to decay fungi is essentially related to its cell wall components and microstructure [16][17][18][19][20].…”

Wood is susceptible to swelling deformation and decay fungi due to moisture adsorption that originates from the dynamic nanopores of the cell wall and the abundant hydroxyl groups in wood components. This study employed as a modifier maleic anhydride (MAn), with the help of acetone as solvent, to diffuse into the wood cell wall, bulk nanopores, and further chemically bond to the hydroxyl groups of wood components, reducing the numbers of free hydroxyl groups and weakening the diffusion of water molecules into the wood cell wall. The derived MAn-bulked wood, compared to the control wood, presented a reduction in water absorptivity (RWA) of ~23% as well as an anti-swelling efficiency (ASE) of ~39% after immersion in water for 228 h, and showed an improvement in decay resistance of 81.42% against white-rot fungus and 69.79% against brown-rot fungus, respectively. The method of combined cell wall bulking and hydroxyl group bonding could effectively improve the dimensional stability and decay resistance with lower doses of modifier, providing a new strategy for wood durability improvement.

“…vary considerably across species as do their expression levels [24,25,26,27]. Also, genetic mutations, microRNAs, transcription factors such as MYB, bHLH, WD40, WRKY, NAC, etc., have been linked to the regulation of anthocyanin biosynthetic structural genes through varying complex mechanisms among plants [14,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41]. Therefore, in order to pinpoint the major players associated with quantitative and qualitative variations of anthocyanins in plant, a thorough investigation is necessary.…”

Purple turnip Brassica rapa ssp. rapa is highly appreciated by consumers but the metabolites and molecular mechanisms underlying the root skin pigmentation remain open to study. Herein, we analyzed the anthocyanin composition in purple turnip (PT) and green turnip (GT) at five developmental stages. A total of 21 anthocyanins were detected and classified into the six major anthocynanin aglycones. Distinctly, PT contains 20 times higher levels of anthocyanins than GT, which explain the difference in the root skin pigmentation. We further sequenced the transcriptomes and analyzed the differentially expressed genes between the two turnips. We found that PT essentially diverts dihydroflavonols to the biosynthesis of anthocyanins over flavonols biosynthesis by strongly down-regulating one flavonol synthase gene, while strikingly up-regulating dihydroflavonol 4-reductase (DFR), anthocyanidin synthase and UDP-glucose: flavonoid-3-O-glucosyltransferase genes as compared to GT. Moreover, a nonsense mutation identified in the coding sequence of the DFR gene may lead to a nonfunctional protein, adding another hurdle to the accumulation of anthocyanin in GT. We also uncovered several key members of MYB, bHLH and WRKY families as the putative main drivers of transcriptional changes between the two turnips. Overall, this study provides new tools for modifying anthocyanin content and improving turnip nutritional quality.
