Proposal to classify phylotype I strains as sp. nov., and a genomic comparison between members of the genus .

A Gram-negative, aerobic, rod-shaped, motile bacterium with multi-flagella, strain RS, was isolated from bacterial wilt of tobacco in Yuxi city of Yunnan province, China. The strain contains the major fatty acids of C, summed feature 3 (C 7 and/or C 6), and summed feature 8 (C 7 and/or C 6). The polar lipid profile of strain RS consists of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, and unidentified aminophospholipid.

[Congenital ectrodactyly caused by chromosome 10q24.31 duplication and its pathogenetic analysis].

In order to investigate the genetic variations and the clinical manifestations of a range of congenital ectrodactyly family and to summarize the split hand/foot malformation (SHFM) types and their related pathogenic genes, we conducted phenotypic analyses of patient's limbs by physical and X-ray examination. The haplotypes were analyzed by using the extracted genes from peripheral blood on D10S1709, D10S192, D10S597, D10S1693 and D10S587 loci, and the mutation duplication loci were confirmed by Array-CGH detection. The pathogenic factors and inheritance pattern of SHFM were analyzed based on family investigation and gene analysis.

Short-term alteration of nitrogen supply prior to harvest affects quality in hydroponic-cultivated spinach (Spinacia oleracea).

Background: Quality-associated problems, such as excessive in planta accumulation of oxalate, often arise in soillessly cultivated spinach (Spinacia oleracea). Maintaining a higher level of ammonium (NH₄⁺) compared to nitrate (NO₃⁻) during the growth period can effectively decrease the oxalate content in hydroponically cultivated vegetables. However, long-term exposure to high concentrations of NH₄⁺ induces toxicity in plants, and thus decreases the biomass production.
