DOI: 10.1007/s10682-019-09985-0
Abstract: The South African Cape fynbos heath Erica coccinea subsp. coccinea is polymorphic for post-fire regeneration mode (seeder/resprouter), flower colour (red/yellow), flowering time (summer-autumn/winter-spring), as well as anther size. These polymorphisms tend to occur between, rather… read more here.

DOI: 10.1093/aob/mcac069
Abstract: Abstract Background The colours of flowers are of key interest to plant and pollination biologists. An increasing number of studies have investigated the importance of saturation of flower colours (often called ‘spectral purity’ or ‘chroma’)… read more here.

DOI: 10.1093/aobpla/plae053
Abstract: Abstract Systems-wide understanding of gene expression profile regulating flower colour formation in Rhododendron simsii Planchon is insufficient. In this research, integration analysis of ribonucleic acid (RNA)omics and microRNAome were performed to reveal the molecular mechanism… read more here.

Abstract: Invasive plants displaying disparate pollination environments and abiotic conditions in native and non-native ranges provide ideal systems to test the role of different ecological factors driving flower colour variation. We quantified corolla reflectance of the… read more here.

DOI: 10.1111/plb.13682
Abstract: Flower colour is an important mediator of plant-pollinator interactions. While the reflectance of light from the flower surface and background are governed by physical properties, the perceptual interpretation of such information is generated by complex… read more here.

DOI: 10.3389/fpls.2024.1304849
Abstract: The diversity of flower colours in nature provides quantifiable evidence for how visitations by colour sensing insect pollinators can drive the evolution of angiosperm visual signalling. Recent research shows that both biotic and abiotic factors… read more here.

Understanding Alstroemeria pallida Flower Colour: Links between Phenotype, Anthocyanins and Gene Expression
Sign Up to like & getrecommendations! Published in 2020 at "Plants"
DOI: 10.3390/plants10010055
Abstract: Flower colour is mainly due to the accumulation of flavonoids, carotenoids and betalains in the petals. Of these pigments, flavonoids are responsible for a wide variety of colours ranging from pale yellow (flavones, flavonols and… read more here.
