Most Phalaenopsis cultivars have almost no aroma, with a few exceptions. presents significant challenges in fragrance breeding due to its weak aroma and low fertility. It is therefore necessary identify the components key regulatory genes like 'Orange Beauty', 'Brother Sara Gold', 'Purple Martin', 'H026', 'SK16', 'SX098', 'SH51', improve of common Phalaenopsis.

Integrated Multiomics Analysis Sheds Light on the Mechanisms of Color and Fragrance Biosynthesis in Wintersweet Flowers

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(4), С. 1684 - 1684

Опубликована: Фев. 16, 2025

Wintersweet (Chimonanthus praecox) is known for its flowering in winter and rich floral aroma; the whole flower yellow inner petals are red. In this study, we chose wintersweet genotypes HLT040 HLT015 as research materials, studied co-regulatory mechanism of color fragrance through metabolomics transcriptomics. This study found that there were more flavonoids HLT015, anthocyanins (cyanidin-3-O-rutinoside cyanidin-3-O-glucoside) only present but contained monoterpenes FVBPs (phenylpropanoid volatile compounds) than HLT015. We constructed putative benzenoids phenylpropanoid metabolism pathway well terpene pathways. some linkages between different structural genes metabolites wintersweet, screened out 39 TFs may be related to one or yeast one-hybrid assay, CpERF7 was able interact with promoter CpANS1, while CpbHLH50 CpMYB21 interacted CpTPS4. provides a theoretical basis understanding wintersweet.

Functional Characterization of 5-O-Glycosyltranferase Transforming 3-O Anthocyanins into 3,5-O Anthocyanins in Freesia hybrida

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(10), С. 4542 - 4542

Опубликована: Май 9, 2025

Floral coloration in Freesia hybrida is predominantly attributed to anthocyanins, with glycosylation playing a critical role their stability and diversity. This study investigates the molecular mechanisms underlying color variation between F. cultivars, focusing on anthocyanin 5-O-glucosyltransferases (An5GTs). HPLC analysis revealed that ‘Pink Passion’ petals accumulate 3,5-O-diglucosidic absent ‘Red River®’ ‘Ambiance’. RNA-seq identified seven candidate Fh5GT genes, phylogenetic subcellular localization analyses confirming classification as cytosolic glycosyltransferases. Expression profiling highlighted elevated transcript levels of Fh5GT1, Fh5GT3, Fh5GT7 Passion’, correlating its di-glucosidic accumulation. In vitro enzymatic assays demonstrated Fh5GT3 preferentially glucosylate 3-O-monoglucosidic anthocyanins form stable 3,5-O-diglucosides, minimal activity anthocyanidins generate 5-O-glucosidic anthocyanins. Heterologous expression Arabidopsis complemented deficiency 5gt mutants, restoring pigmentation. These findings elucidate potential 5GTs modulating floral diversity through modification, providing insights for targeted breeding strategies enhance ornamental traits horticultural species.

Synergistic Effects of Flower Color and Mechanical Barriers on Pollinator Selection Within the Papilionoideae of Fabaceae

Plants, Год журнала: 2025, Номер 14(11), С. 1568 - 1568

Опубликована: Май 22, 2025

Current understanding of synergistic trait effects in plant–pollinator systems remains limited, particularly regarding combined visual and mechanical screening mechanisms. Given the specialized flower opening mechanisms diverse color signals Papilionoideae Fabaceae, this study examines how floral traits jointly mediate pollinator selection five co-flowering sympatric species. The structure typically features a keel formed by fused petal lobes that encloses reproductive organs, with operative strength thresholds directly reflecting resistance required to dehisce access nectar/pollen. Flower insect capabilities were quantified, visitation behaviors observed under natural conditions. Significant interspecific variation (12.59–20.25 mN) was identified, visiting insects consistently exhibiting strengths exceeding these thresholds, suggesting barriers selectively filter pollinators. Non-visiting exhibited either insufficient or excessive relative which is related flower-visiting preferences different insects. Although no linear correlation found between (RGB space) strength, analysis revealed where attracted specific pollinators from subset capable overcoming barriers. These findings demonstrate function as complementary filters, optimizing efficiency excluding ineffective visitors. highlights necessity explore multi-trait interactions co-evolution, implications for biodiversity conservation ecosystem service management.

Patterns of change in floral color and odor of Lonicera calcarata are in relation to pollinator behavior

Abstract Floral color and odor serve as attractants for pollinators. It remains unclear how changes in these traits color‐change species interact with pollinators impact a plant's reproductive success. Lonicera calcarata flowers change from white (Night 1 [N1] Day [D1]) through yellow 2 [N2]) orange (Day [D2]) to orange‐red 3 [N3] [D3]). Our research showed that floral characters, stigma activity, nectar production spectral reflectance decreased the flowering phases. mainly comprised fatty acids, aldehydes, monoterpenes alcohols, especially n‐ hexadecanoic acid, hexadecanal 3‐carene. peaked on N1 N3, largely due presence of acids. The emission acid was higher N3 compared other phases, while remained constant throughout stages. 3‐carene highest N1. pollinated by moth Chorodna strixaria , butterfly Acosmeryx naga three bumblebees ( Bombus melanurus B. eximius sonani ) they all preferred visit (younger) flowers. Moths had preference no significant hexadecanal. Seed sets nocturnal pollination control treatments were not significantly different. could produce seeds self‐pollination; cross‐pollination increased seed set. guides younger more rewards activity. Different chemical compounds may only attract but also avoid herbivore damage.
