Sweet potato, Ipomoea batatas (L.) Lam., is an important food and industrial material crop throughout the world. It is also an alternative source of bio-energy as a raw material for fuel production. China is the biggest sweet potato producer in the world. Biotechnology offers great potential for improving disease, pest and stress resistance and nutritional quality of sweet potato. In the past d...

was Ampli-Taq DNA polymer-ase. Another problem may be attributable to the production of uneven peak-height patterns, which are caused by differences in the efficiency of dideoxy termination at different bases and are affected by sequence context as well. Zakeri et al. (5) reported that a heterozygous C peak was much smaller in size than a heterozygous G peak. This is in agreement with our resul...

Chemosensation in C. elegans Worms have a very simple chemosensory system composed of 32 neurons. Despite this simplicity, they are capable of detecting and appropriately responding to a Dallas, Texas 75235-9111 wide range of chemicals (Bargmann et al. Lucretius, one of the early Greek atomists, suggested have shown that chemoattraction to a number of mole-that all substances having odor gave o...

Life-cycle assessment (LCA) was used to evaluate the energy efficiency and environmental impacts of sweet potato-based bioethanol production. The scope covered all stages in the life cycle of bioethanol production, including the cultivation and treatment, transport, as well as bioethanol conversion of sweet potato. Results show that the net energy ratio of sweet potato-based bioethanol is 1.48 ...

Citrus is one of the most important and widely grown fruit crop with global production ranking firstly among all the fruit crops in the world. Sweet orange accounts for more than half of the Citrus production both in fresh fruit and processed juice. We have sequenced the draft genome of a double-haploid sweet orange (C. sinensis cv. Valencia), and constructed the Citrus sinensis annotation proj...

T1r3 is a critical subunit of T1r sweet taste receptors. Here we studied how the absence of T1r3 impacts responses to sweet stimuli by taste neurons in the nucleus tractus solitarius (NTS) of the mouse. The consequences bear on the multiplicity of sweet taste receptors and how T1r3 influences the distribution of central gustatory neurons. Taste responses to glycine, sucrose, NaCl, HCl, and quin...

This paper shows how intermodulation distortion, IMD, sweet spots can be used as a practically meaningful technology to design highly linear microwave power amplifiers. It starts by reviewing the physical origins of these points of large signal to nonlinear distortion ratio, distinguishing the ones uniquely determined by the active device’s quiescent point – small-signal IMD sweet spots – from ...

In Brazil, Potyvirus species in sweet potatoes have been detected mostly by serology. Here, we report the complete genome sequences of two Potyvirus species, Sweet potato feathery mottle virus strain (SPFMV-UNB-01) and Sweet potato virus G strain (SPVG-UNB-01).

a sweet water-soluble protein that reminds stable over wide ranges of temperature and ph, brazzein has various applications. its tastes like cane sugar but have no calories. however, the extraction of brazzein from its natural source is expensive and not applicable. in this study we used recombinant dna technology to provide an alternative option for cheaper mass production of brazzein. a brazz...
