Klebsiella oxytoca Rs-5 isolated with ACC (1-aminocyclopropane-1-carboxylate) deaminase activity as the sole nitrogen source could obviously promote cotton seedling growth under salt stress and produce phytohormone indole-3-acetic acid (IAA). The amount of IAA produced by the strain Rs-5 was measured, and the effect of IAA on cotton growth under salt stress(More)
During Drosophila optic lobe development, proliferation and differentiation must be tightly modulated to reach its normal size for proper functioning. The JAK/STAT pathway plays pleiotropic roles in Drosophila development and in the larval brain, has been shown to inhibit medulla neuroblast formation. In this study, we find that JAK/STAT activity is(More)
A plant growth-promoting rhizobacterial strain Rs-2 with 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity was isolated from salinized soils using ACC as the sole nitrogen source. Based on its physiological and biochemical properties and 16S rDNA sequence analysis, this strain was identified as Raoultella planticola. The maximum value of nitrogen(More)
OBJECTIVE To evaluate the DEC1 expression of periodontal ligament tissue and gingival tissue in the patients with chronic periodontitis. METHODS 20 non-smoking patients with chronic periodontitis and 20 healthy individuals were enrolled. Periodontal ligament tissue and gingival tissue samples from healthy subjects were collected during teeth extraction(More)
Mesoporous MgO architectures were successfully synthesized by the direct thermal transformation of the sacrificial oxalate template. The as-prepared mesoporous architectures were characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray energy dispersive spectroscopy (EDS), Fourier(More)
Osteosarcoma is the most common type of primary malignant tumor of the bone. However, mechanisms underlying osteosarcoma cell proliferation are poorly understood. The present study shows that RBEL1, a newly identified Rab-like GTPase, may be a key regulator of osteosarcoma cell proliferation. Knockdown of RBEL1 in osteosarcoma cells resulted in impaired(More)
A previous study found the key transcription factor of Litopenaeus vannamei PERK-eIF2α pathway cyclic AMP-dependent transcription factor 4 (LvATF4) was involved in the transcriptional regulation of white spot syndrome virus (WSSV) gene wsv023. Knocked-down expression of LvATF4 reduced the viral copy number and the cumulative mortality of WSSV-infected(More)
