Fascinating single‐cell red algae: models for evolution and adaptation
New Phytologist, EarlyView.Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Astaxanthin and Related Xanthophylls
, 2014 This chapter describes astaxanthin and other xanthophylls, which are a class of carotenoids with oxygenated groups in their structure and characteristic vivid colors. Taking astaxanthin as a key example, the presented concepts focus on the functional aspects and applications of xanthophylls, such as their nutritional value, potential for protection ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Plant biofortification with phytonutrients typically relies on metabolic engineering strategies known as ‘push’ (enhancing biosynthetic flux), ‘block’ (inhibiting competing pathways) and ‘pull’ (promoting metabolite storage). Here, we describe a novel synthetic compound, X57, that simultaneously targets biosynthesis, competition and storage to

Stability of carotenoids toward UV-irradiation in hexane solution [PDF]
Journal of the Serbian Chemical Society, 2008 The stabilities of four selected carotenoids dissolved in hexane, two carotenes and two xanthophylls, toward UV-irradiation of three different ranges (UV-A, UV-B and UV-C) were studied in this work. The carotenoids underwent bleaching via a probable free

Poultry Science, 1985 Abstract Four marigold products, a bixin product, and two synthetic xanthophylls, canthaxanthin and β-apo-8′-carotenal, were evaluated for their effects on xanthophyll utilization and coloring capability in egg yolks. The selected sources, obtained as commercially available products, were added to a yellow corn basal diet containing 11 mg total ...

Pro‐Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field
Plant Biotechnology Journal, EarlyView.ABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content
