Ectopic Expression of the Gene in Cotton Improves Drought Tolerance and Yield Under Drought Stress in the Field.

In some plants, sucrose: sucrose 1-fructosyltransferase (1-SST) is the first irreversible key enzyme in fructan biosynthesis. Studies have shown that fructan accumulation enhances abiotic stress tolerance of plants. To investigate the role of in drought stress responses, a total of 37 cotton plants expressing a gene from were developed by -mediated transformation.

Down-expression of TaPIN1s Increases the Tiller Number and Grain Yield in Wheat.

Background: Tiller number is a factor determining panicle number and grain yield in wheat (Triticum aestivum). Auxin plays an important role in the regulation of branch production. PIN-FORMED 1 (PIN1), an auxin efflux carrier, plays a role in the regulation of tiller number in rice (Oryza sativa); however, little is known on the roles of PIN1 in wheat.

Genome-Wide Characterization and Expression Analysis Provide Basis to the Biological Function of Cotton FBA Genes.

Fructose-1,6-biphosphate aldolase (FBA) is a multifunctional enzyme in plants, which participates in the process of Calvin-Benson cycle, glycolysis and gluconeogenesis. Despite the importance of genes in regulating plant growth, development and abiotic stress responses, little is known about their roles in cotton. In the present study, we performed a genome-wide identification and characterization of in .

Guillain-Barré syndrome in a patient with multiple myeloma after bortezomib therapy: A case report.

Background: Bortezomib is a first-line drug approved for patients with multiple myeloma (MM) and has significantly increased their overall survival. However, bortezomib-induced peripheral neuropathy (PN) remains a significant side effect that has led to its discontinuation in some patients. Guillain-Barré syndrome (GBS) is recognized as an immune-mediated PN characterized by the involvement of multiple nerve roots and peripheral nerves and albuminocytologic dissociation in cerebrospinal fluid (CSF) tests.

Primary succession of soil enzyme activity and heterotrophic microbial communities along the chronosequence of Tianshan Mountains No. 1 Glacier, China.

We investigated the primary successions of soil enzyme activity and heterotrophic microbial communities at the forefields of the Tianshan Mountains No. 1 Glacier by investigating soil microbial processes (microbial biomass and nitrogen mineralization), enzyme activity and community-level physiological profiling. Soils deglaciated between 1959 and 2008 (0, 5, 17, 31 and 44 years) were collected.

[Relationships of wheat leaf stomatal traits with wheat yield and drought-resistance].

Taking the DH population of wheat cultivar Hanxuan10/Lumai14 as test object, and by the methods of correlation analysis and path analysis, this paper studied the relationships of the flag leaf stomatal density (SD), stomatal length and width (SL and SW), stomatal conductance (g(s)), photosynthetic rate (P(n)), and transpiration rate (T(r)) on the 10th and 20th day after anthesis with the yield and the index of drought-resistance under the conditions of drought stress and normal irrigation. Under the two conditions, most of the test leaf traits on the 10th day after anthesis had less correlation with the yield and the index of drought-resistance, whereas the leaf traits on the 20th day after anthesis had significant positive correlations with thousand kernel weight but less correlation with grain number per ear, grain yield per plant, and index of drought-resistance. Path analysis showed that g(s), P(n), and T(r) were the main factors affecting the grain yield per plant (YPP) and the index of drought resistance (IDR), and the effects were stronger both in direct and in indirect ways.

[Inhibitory effects of HSV-tk/GCV system mediated by recombinant adeno-associated virus 2 on rabbit lens epithelial cells].

Objective: To study the inhibitory effects of recombinant adeno-associated virus 2 (rAAV2)-mediated herpes simplex virus thymidine kinase/ganciclovir (HSV-tk/GCV) system on the rabbit lens epithelial cells (N/N1003A) in vitro and to investigate the mechanism of cell death.

Methods: After N/N1003A cells had been transfected with rAAV2-EGFP, expression of enhanced green fluorescent protein (EGFP) were observed by inverted fluorescent microscope and the transfection efficiency was detected by flow cytometry. N/N1003A cells were infected by recombinant virus rAAV2/HSV-tk as the treated group, and the uninfected N/N1003A cells were used as the controls.

[Construction and expression of recombinant adeno-associated virus vector containing HSV1-TK gene].

Objective: To construct the recombinant adeno-associated virus(rAAV) vector plasmid pSNAV2.0-TK containing HSV1-TK gene, to produce recombinant adeno-associated virus rAAV2/HSV1-TK, and to detect the integration and expression of HSV1-TK gene in lens epithelial cells transfected by rAAV2/HSV1-TK, and to provide foundation for gene therapy of posterior capsular opacification.

Methods: The recombinant vector plasmid constructed by gene recombinant technology was analyzed by PCR and restriction enzyme digestion.
