The effects of anthocyanin-free aqueous extract Hibiscus sabdariffa petal on body weight gain, organ/body ratio and selected toxicological indices in cadmium intoxicated male rats were examined. When compared to cadmium-free extract-free control ,cadmium caused significant (P < 0.05) decreases prostate/body testis/body ratios .Prostatic acid phosphatase activity (only prostate) catalase acti...

Paeonia rockii is a wild tree peony species with large and dark purple variegations at the base of its petals. It is the genetic resource for various variegation patterns in tree peony cultivars, which is in contrast to the pure white petals of Paeonia ostii. However, the molecular mechanism underlying the formation of variegation in this plant is still unknown. Here, we conducted Illumina tran...

Oilseed rape (Brassica napus L.), which has yellow flowers, is both an important oil crop and a traditional tourism resource in China, whereas the Orychophragmus violaceus, which has purple flowers, likely possesses a candidate gene or genes to alter the flower colour of oilseed rape. A previously established B. napus line has a particular pair of O. violaceus chromosomes (M4) and exhibits slig...

Identifying the genetic basis of parallelism reveals the means by which evolution repeats itself and shows what aspects-if any-may be predictable. The recently tetraploid luteus group of Mimulus contains five species native to central Chile, three of which have evolved extensive red floral pigmentation using at least two distinct loci . Here we show that the parallel evolution of petal lobe ant...

To shorten the time required for breeding and optimize the risk-cost/benefit ratio of genetically modified ornamental plants, we applied heavy-ion beam irradiation to wild-type and genetically modified torenia (Torenia fournieri Lind. CV. ‘Crown Violet’ plants in which petal color and pattern had been modified by controlling two anthocyanin biosynthesis-related genes encoding chalcone synthase ...

Abstract Objectives This study aimed to evaluate the functional activity and phytochemical composition in flower petals of Paeonia delavayi (P. delavayi) different colors. Materials Methods P. petal extracts were prepared by maceration methanol, including purple extract (PPE), red (RPE), yellow (YPE), their antioxidant α-glucosidase acetylcholinesterase inhibition activities evaluated. To corre...

Bulb color is an important consumer trait for onion (Allium cepa L., Allioideae, Asparagales). The bulbs accumulate a range of flavonoid compounds, including anthocyanins (red), flavonols (pale yellow), and chalcones (bright yellow). Flavonoid regulation is poorly characterized in onion and in other plants belonging to the Asparagales, despite being a major plant order containing many important...
