The scent of roses (Rosa x hybrida) is composed of hundreds of volatile molecules. Monoterpenes represent up to 70% percent of the scent content in some cultivars, such as the Papa Meilland rose. Monoterpene biosynthesis in plants relies on plastid-localized terpene synthases. Combining transcriptomic and genetic approaches, we show that the Nudix hydrolase RhNUDX1, localized in the cytoplasm, ...
Background: The family Rosaceae, include some large genus, eg the genus Rose includes 200 species and 18000 cultivars. Objective: Aim of this study is to determine the chemical composition of the hydrodistilled oil of the leaves of Sanguisorba minor scop, of Iranian origin for the first time. Methods: The essential oil obtained by hydrodistillation of Sanguisorba minor was analyzed by GC and...
Sugars and sorbitol were determined on corn (Zea mays L.) kernels harvested at various developmental stages, using sugary (su), sugary-sugary enhancer (su se), and starchy (Su) cultivars. In all cultivars tested, the sorbitol content increased from trace amounts in unpollinated ovules to a maximum at about the time that rapid starch synthesis was proceeding. Thereafter, sorbitol and sugars decr...
The characteristics of wine phenolics found in several North American and (for comparison) European grape cultivars grown in China were analyzed. This was done to find non-Vitis vinifera wines with prominent features in order to diversify the kinds of wines. The phenolic richness and antioxidant activity decreased in the order: red > rose > white wines. In the red wines, the American grape 'Cyn...
Chrysanthemums (Chrysanthemum×morifolium Ramat.) are an important cut-flower and potted plant crop in the horticultural industry world wide. Chrysanthemums express the flavonoid 3'-hydroxylase (F3'H) gene and thus accumulate anthocyanins derived from cyanidin in their inflorescences which appear pink/red. Delphinidin-based anthocyanins are lacking due to the deficiency of a flavonoid 3', 5'-hyd...
Abstract Flowers have received special attention not only for their ornamental nature but also nutraceutical, cosmetic, aromatic, and culinary properties. This study aimed to characterize physicochemical attributes the antioxidant capacity of flowers four gladiolus cultivars. The cultivars used were White Friendship, Rose Supreme, Jester, T704. We analyzed content total soluble solids (SS), tit...
erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...
