Dye-sensitized solar cells (DSSCs) were assembled by using the bougainvillea flowers, red turnip and the purple wild Sicilian prickly pear fruit juice extracts as natural sensitizers of TiO(2) films. The yellow orange indicaxanthin and the red purple betacyanins are the main components in the cocktail of natural dyes obtained from these natural products. The best overall solar energy conversion efficiency of 1.7% was obtained, under AM 1.5 irradiation, with the red turnip extract, that showed a remarkable current density (Jsc = 9.5 mA/cm(2)) and a high IPCE value (65% at lambda = 470 nm). Also the purple extract of the wild Sicilian prickly pear fruit showed interesting performances, with a Jsc of 9.4 mA/cm(2), corresponding to a solar to electrical power conversion of 1.26%.

Rapeseed (Brassica napus L.) possesses substantial economic value as an oil, vegetable, and forage crop, while also exhibiting notable ornamental characteristics. Recent advances in flower colour breeding have significantly enhanced the visual appeal of rapeseed, with anthocyanins identified as the primary contributor to the development of red, purple, and pink flowers.

Exchangeable aluminum (Al) ions released from acidic soils with pH < 5.5 inhibit root elongation of crops, ultimately leading to yield reduced. It is necessary to identify the quantitative trait locus (QTLs) and candidate genes that confer toxicity resistance to understand the mechanism and improve tolerance of rapeseed.

Phenylalanine ammonia-lyase (PAL) acts as the rate-limiting enzyme for anthocyanin biosynthesis through the phenylpropanoid pathway, a crucial component of plant secondary metabolism. The gene family plays a crucial role in plants' defense and stress responses, but its in silico identification and expression analyses in under different abiotic stresses remain unexplored. In this study, nine , seven , four , and seventeen genes were obtained from the genomes of , , , and , respectively.
