The current nitrogen fertilization for sugarcane production in Guangxi, the major sugarcane-producing area in China, is very high. We aim to reduce nitrogen fertilization and improve sugarcane production in Guangxi with the help of indigenous sugarcane-associated nitrogen-fixing bacteria. We initially obtained 196 fast-growing bacterial isolates associated(More)
Members of the genus Microbacterium lineage of Gram-positive actinobacteria are increasingly being reported to display significant traits associated with environmental biotechnology and bioengineering. 16SH is a nitrogen-fixing bacterial strain isolated from a surface-sterilized stem of sugarcane grown in Guangxi, China. Analysis of 16S rRNA gene sequences(More)
Grain chalkiness is a complex trait adversely affecting appearance and milling quality, and therefore has been one of principal targets for rice improvement. Eliminating chalkiness from rice has been a daunting task due to the complex interaction between genotype and environment and the lack of molecular markers. In addition, the molecular mechanisms(More)
AIMD (additive increase and multiplicative decrease) algorithm has been used in many congestion control protocols , including TCP in the Internet. In this paper, we compare AIMD and MAIMD (multiplicative additive increase and multiplicative decrease). Our evaluation shows that the convergence speeds to fair states of AIMD and MAIMD are close to each other.(More)
The endophytic bacterium, Sphingomonas SaMR12, isolated from Sedum alfredii Hance, appears to increase plant biomass and zinc-extraction from contaminated soil; however, the mechanism by which this occurs is not clear. Here, the ability of SaMR12 to promote zinc extraction and its effects on root morphology and exudation were examined in hydroponics. Zinc(More)
BACKGROUND Chalkiness has a deleterious influence on rice appearance and milling quality. We identified a notched-belly mutant with a high percentage of white-belly, and thereby developed a novel comparison system that can minimize the influence of genetic background and growing conditions. Using this mutant, we examined the differences in chemical(More)
This study aims to elucidate the role of bracts of rice spikelets in terms of nitrogen (N) remobilization, focusing on amino acid (AA). A pot experiment with three treatments of N rate was performed, using the japonica rice cultivar Ningjing5 as material. Dynamic changes of AA, mainly the protein amino acids, in leaf, grain, and bracts were monitored, and(More)
Asian yellow pond turtle (Mauremys mutica) is an endangered species, being listed in the IUCN red list of threatened species. In China, most living resources are kept in turtle farms. Insufficient molecular markers have hindered the effective management and artificial breeding programs of this important species. In this study, we discovered and validated 43(More)
A multiplex PCR system that consisted of 12 pairs of novel primers based on the transcriptome of the mud carp was developed and characterized for genetic polymorphism analysis in 64 wild individuals in our laboratory. The microsatellite loci exhibited a range of alleles of 3 < K < 7 with an average of 4.25. The observed heterozygosity ranged from 0.375 to(More)
