Oleoyl-phosphatidylcholine desaturase (FAD2) is a key enzyme involved in fatty acid desaturation in oilseeds, which is affected by environmental temperature. The results of this study show that FAD2 is regulated in vivo via temperature-dependent endogenous oxygen concentrations in developing sunflower (Helianthus annuus L.) seeds. By combining in vivo oxygen profiling, in situ hybridization of ...

This study investigated the effects of cocoa butter and sunflower oil alone and in combination on performance, some biochemical parameters, immunoglobulin, and antioxidant vitamin status in Wistar rats. Forty-eight male rats were assigned to four groups, consisting of 12 rats with 3 replicates. Control received balanced rat diet without oil, cocoa butter group received 3.5% cocoa butter, sunflo...

production of high yielding hybrid cultivars is among the main objectives of breeding programs in sunflower and on evaluation of the combining ability of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. this study was conducted to investigate the general and specific combining ability and the mode of inheritance for agronomic and seed q...

Mexican sunflower is native to Mexico and Central America and was introduced into China early last century. Now it has widely naturalized and is exhibiting increasing invasiveness in South China. As this species often dominates bare ground, a habitat characterized by extreme fluctuation in temperature and water, it is reasonable to hypothesize that it has special adaptations to high temperature...

The objective of the current study was to evaluate the effect of dietary fat type and level on broiler meat quality. A 2 × 3 factorial arrangement with 2 types of fat including neutralized sunflower soapstock (NSS) and soybean oil (SO) at 3 levels of fat inclusion (2, 4, and 6%) was used with 5 replicates per treatment using 750 one-day-old broiler chicks in a completely randomized design. At t...

Olive oil consumption is protective against risk factors for cardiovascular and cancer diseases. A nutrigenomic approach was performed to assess whether changes in gene expression could occur in human peripheral blood mononuclear cells after oli ve oil ingestion at postprandial state. Six healthy male volunteers ingested, at fasting state, 50 ml of olive oil. Prior to intervention a 1-week wash...

A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...

Salicylic acid (SA) is an endogenous plant growth regulator, acting as non enzymatic antioxidant and has a regulatory effect on some physiological and biochemical processes. Therefore, this work was conducted during two successive summer seasons to evaluate the performance of two sunflower cultivars (Sakha 53 and Giza 102) to salicylic acid. The plants were grown at the experimental station of ...
