Morphological studies showed that tree shape in Bitter sweet orange and Yuma citrange was spheroid with spreading growth habit and wide branch angle. Leaves were simple with dark green color, medium size and brevipetiolate in Sour orange while Yuma citrange had trifoliate leaves with medium and green color. Bitter sweet orange had the highest leaf lamina length (10.4 mm) than other rootstocks. ...

With the development of science and technology, the problem about the quality safety traceability of agricultural products has already become the hot topic of researchers in various fields. Cucumber is one of the main vegetable crops in China. It is convenient for eating and contains various beneficial minerals. With the constant expansion of the planting areas, it plays a more and more importa...

The effect of ultraviolet B (UV-B) radiation on the thermal sensitivity of cucumber (Cucumis sativus L.) was studied using UV-B-sensitive cv Poinsett 76 and UV-B-resistant cv Ashley grown under control and elevated (300 mW m-2) UV-B radiation levels. Using both cotyledon and leaf discs, the ability of the tissue to reduce triphenyl tetrazolium chloride (TTC) was determined after treatment at 50...

Corrections to “Recipe development and preparations” Approximately 50 g of uncooked bitter melon per one cup (250 ml) of raw ingredients was added to each dish, except curry dish. The curry dish does not have any other ingredients besides bitter melon and therefore contained approximately 61 g of bitter melon per onehalf cup (125 ml). Each of the raw ingredients in these recipes (except the cur...

Nutrient deprivation can lead to dramatic changes in feeding behavior, including acceptance of foods that are normally rejected. In flies, this behavioral shift depends in part on reciprocal sensitization and desensitization of sweet and bitter taste, respectively. However, the mechanisms for bitter taste modulation remain unclear. Here, we identify a set of octopaminergic/tyraminergic neurons,...

Human bitter taste is mediated by approximately 25 members of the human TAS2 receptor (hTAS2R) gene family. The hTAS2R genes are expressed in taste buds of gustatory papillae on the tongue surface. Because many naturally occurring bitter compounds are toxic, bitter taste receptors are believed to serve as warning sensors against the ingestion of toxic food compounds. An important question is wh...

The ability to detect bitter tastes is important for animals; it can help them to avoid ingesting harmful substances. Bitter taste perception is mainly mediated by bitter taste receptor proteins, which are encoded by members of the Tas2r gene family and vary with the dietary preference of a specific species. Although individuals with different genotypes differ in bitterness recognition capabili...

Chickens sense the bitter taste of structurally different molecules with merely three bitter taste receptors (Gallus gallus taste 2 receptors, ggTas2rs), representing a minimal case of bitter perception. Some bitter compounds like quinine, diphenidol and chlorpheniramine, activate all three ggTas2rs, while others selectively activate one or two of the receptors. We focus on bitter compounds wit...

Momordica charantia L. (Bitter gourd) is a flowering vine in the family of Cucurbitaceae. It contains an array of novel and biologically active phytochemicals including triterpenes, proteins and steroids. Medicinally, the plant has a long history of use by the indigenous people as a folk medicine. Bitter gourd is often used in Chinese cooking for its bitter flavor, typically in stir-fries, soup...

Cinnamic acid (CA), which is a well-known major autotoxin secreted by the roots in cucumber continuous cropping, has been proven to exhibit inhibitory regulation of plant morphogenesis and development. Melatonin (MT) has been recently demonstrated to play important roles in alleviating plant abiotic stresses. To investigate whether MT supplementation could improve cucumber seedling growth under...
