The purpose of this work was 2-fold; first, a molecular/evolutionary characterization of three sucrose synthase genes from citrus, and second, an analysis of their differential expression related to potential physiological function. Three non-allelic genes (CitSUS1, CitSUSA and CitSUS2) encoding sucrose synthase were isolated from citrus fruit (Citrus unshiu Marc.). Phylogenetic analysis from t...

nature has great importance on prehistoric human life and attention to the environment and discovering mysteries of life which influence their life, always have been considered as concerns of prehistoric people. the elements such as water, wind and earth for primary human were important elements because of no awareness of environment in primary stages of sedentary life. human beings always trie...

The filamentous, nitrogen-fixing cyanobacterium Anabaena sp. strain PCC 7120 accumulates sucrose as a compatible solute against salt stress. Sucrose-phosphate synthase activity, which is responsible for the sucrose synthesis, is increased by salt stress, but the mechanism underlying the regulation of sucrose synthesis remains unknown. In the present study, a response regulator, OrrA, was shown ...

The acceptability of four transformer top-oil thermal models are examined vis-à-vis training with measured data. Acceptability is defined as having the qualities of adequacy, consistency, and accuracy. Metrics are used to characterize the likely deficiencies of these models. It is shown that: the classical IEEE/ANSI standard model is unacceptable for model identification purposes. The linear to...

The author presents a novel assessment of some 270 objects, most them carrying an inscription in Aramaic. These mainly mortars and pestles (and fragments thereof) made from green chert were, although produced Arachosia, found Persepolis. While the interpretation first editor, R. Bowman, these items as ritual objects has never met with approval, their purpose so far been elusive. By means quanti...
