Effect of biocomposite edible coatings based on pea starch and guar gum on nutritional quality of ‘Valencia’ orange during storage [PDF]

open access: yes, 2018
Application of environmentally friendly components is an approach for substitution of synthetic substances in commercial waxes applied to citrus. In this study, the effect of biocomposite edible coatings based on pea starch and guar gum (PSGG) on total ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Distribution, Biosynthesis, and Function of Carotenoids in Oxygenic Phototrophic Algae

open access: yesMarine Drugs
For photosynthesis, oxygenic phototrophic organisms necessarily contain not only chlorophylls but also carotenoids. Various carotenoids have been identified in algae and taxonomic studies of algae have been conducted.

Two Classes of Pigments, Carotenoids and C-Phycocyanin, in Spirulina Powder and Their Antioxidant Activities

open access: yesMolecules, 2018
Arthrospira platensis is the widely available source of spirulina that contains distinctive natural pigments, including carotenoids and C-phycocyanin (C-PC).

Stacked scattering: The key to bright flowers lies in the mesophyll

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The coloration of flowers is caused by wavelength‐selective absorption by pigments and scattering of light by floral structures. Although the molecular, physiological, and chemical properties of floral pigments have been studied in considerable detail, how floral structures contribute to the visual signal remains largely unknown.

Evaluation of fruit quality in a lemon cybrid with mandarin mitochondria [PDF]

open access: yes, 2008
Nutritional and organoleptic qualities of fruit are currently very important objectives for plant breeders. Organic acids, sugars and carotenoids were studied by high liquid chromatography on the pulp of a citrus cybrid.

Biological activities and chemical composition of methanolic extracts of selected Autochthonous microalgae strains from the Red Sea [PDF]

open access: yes, 2015
Four lipid-rich microalgal species from the Red Sea belonging to three different genera (Nannochloris, Picochlorum and Desmochloris), previously isolated as novel biodiesel feedstocks, were bioprospected for high-value, bioactive molecules.

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.
