It has been long considered that zinc homeostasis in bacteria is maintained by export systems and uptake systems, which are separately controlled by their own regulators and the uptake systems are negatively regulated by Zur which binds to an about 30-bp AT-rich sequence known as Zur-box present in its target promoters to block the entry of RNA polymerase.(More)
Sugarcane trash addition to the soils was found to alter the structure of microbial communities in soil and increased the number of microbial colonies. The total number of bacterial, fungal and actinomycetes colonies was found to be increased by 2.38, 1.80 and 2.74 folds, respectively, in trash added soil as compared to the conventional one. Further, the(More)
High sugar content is an essential goal in breeding new sugarcane varieties. Sucrose-phosphate synthase (SPS) is a key enzyme that regulates sucrose biosynthesis in plants. Four families of the SPS gene exist in sugarcane. It is important to elucidate the biological functions of SPS genes from different gene families, so as to regulate the expression of(More)
Sugarcane (Saccharum officinarum L.) is the most important sugar crop and a major source of bio-ethanol. Sucrose accumulation is important in sugarcane, but it has not been investigated by transcriptome analysis . In this study, the transcriptome of a high-sucrose sugarcane variety, GT35, was sequenced using high-throughput Solexa technology. A total of(More)
Sucrose synthase is one of the key enzymes involved in sucrose metabolism. In order to increase the sucrose content at the molecular level, it is very necessary to understand the biological function of sucrose synthase gene in sugarcane. In this study, homology cloning and rapid amplification of cDNA ends technology were used to obtain the 2898 bp(More)
The Zur of Xanthomonas campestris functions as a repressor and an activator of putative zinc homeostasis genes via recognizing two distinct sequences within its target promoters ABSTRACT It has been long considered that zinc homeostasis in bacteria is maintained by export systems and uptake systems, which are separately controlled by their own regulators(More)
