The PPR-Domain Protein SOAR1 Regulates Salt Tolerance in Rice.

Previous studies in Arabidopsis reported that the PPR protein SOAR1 plays critical roles in plant response to salt stress. In this study, we reported that expression of the Arabidopsis SOAR1 (AtSOAR1) in rice significantly enhanced salt tolerance at seedling growth stage and promoted grain productivity under salt stress without affecting plant productivity under non-stressful conditions. The transgenic rice lines expressing AtSOAR1 exhibited increased ABA sensitivity in ABA-induced inhibition of seedling growth, and showed altered transcription and splicing of numerous genes associated with salt stress, which may explain salt tolerance of the transgenic plants.

Transparent Microcomposite Films Based on a Ce-Doped LiGd(BO) Scintillator for Radiation Detection.

Scintillators are widely used for high-energy radiation detection. Hybrid inorganic-organic composite scintillators with high light yields, high light decay rates, excellent stability, and low costs are in great demand. Here, we report a novel scintillator composed of Ce-doped LiGd(BO) (LGBO) microphosphors (MPs) and polymethyl methacrylate for X-ray and thermal neutron detection.

Inheritance and breeding of japonica rice with good eating quality in Jiangsu province.

In order to develop a variety of japonica rice with good eating quality suitable for planting in Jiangsu Province, the genetic basis of high quality, disease resistance and high yield japonica rice varieties in Jiangsu Province was systematically studied. The relationship among different rice qualities of cooking, nutrition, and eating was studied by association analysis. It was clear that amylose content was the key factor affecting eating quality.

Upregulation of spinal ASIC1 by miR-485 mediates enterodynia in adult offspring rats with prenatal maternal stress.

Aims: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disease characterized by abdominal pain. Our recent study has shown that the acid-sensitive ion channel 1 (ASIC1) in dorsal root ganglion (DRG) is involved in stomachache of adult offspring rats subjected with prenatal maternal stress (PMS). MiR-485 is predicted to target the expression of ASIC1.

The potential role of HO-1 in regulating the MLK3-MKK7-JNK3 module scaffolded by JIP1 during cerebral ischemia/reperfusion in rats.

Heme oxygenase (HO-1), which may be induced by Cobaltic protoporphyrin IX chloride (CoPPIX) or Rosiglitazone (Ros), is a neuroprotective agent that effectively reduces ischemic stroke. Previous studies have shown that the neuroprotective mechanisms of HO-1 are related to JNK signaling. The expression of HO-1 protects cells from death through the JNK signaling pathway.

[Influence of yeast extract on the fermentation of glucose by the demulsifying strain Alcaligenes sp. S-XJ-1].

The demulsifying strain Alcaligenes sp. S-XJ-1, isolated from oil contaminated soil, was cultivated with glucose as the carbon source. The influences of yeast extract on the growth, demulsifying ability and the element composition of the strain were investigated.

[Substitution mapping of QTL for panicle exertion using CSSL in rice (Oryza sativa L.)].

Panicle exertion, the distance between the leaf cushion of flag and the neck-panicle node, is an important morphological trait, which has significant impact on hybrid seed production of rice. In this study, 94 chromosome segment substitution lines (CSSL), derived from 9311/Nipponbare with 9311 as the recurrent parent, were used to analyze quantitative trait loci (QTL) controlling the panicle exertion. The results showed that 17 CSSL contained QTL for the panicle exertion.

[Identification of SSR markers closely linked to eui gene in rice].

Sex determination is a complex regulatory process of early embryogenesis. Embryo must make a developmental decision to develop as a male or female during gonadogenesis. This paper reviews genetic systems of sex determination, gonadogenesis, key genes involved in sex determination of vertebrates.

[QTL analysis of low-temperature-sensitive pollen sterility in Indica-japonica hybrid rice (Oryza sativa L.)].

There existed a number of biological constraints in exploiting the heterosis of indica-japonica hybrid rice. The low-temperature-sensitive sterility (LTSS) of indica-japonica hybrid has become one of the major problems in indica-japonica hybrid rice breeding after the solution of poor fertility of the hybrids by the finding of wide-compatibility gene. Previous studies revealed that the LTSS might be caused by low-temperature-sensitive pollen sterility (LTSPS).

[Preparation of a monoclonal antibody against methyl jasmonate and quantification of jasmonic acid in florets of wheat and Italian ryegrass].

A monoclonal antibody (McAb) against methyl jasmonate (MeJA) was prepared and characterized. The McAb, J2-4B, was derived from an immunogen in which the C1-COOH of jasmonic acid (JA) was conjugated to the -NH2 of keyhole limpet hemocyanin (KLH). The McAb showed a higher recognition ability to methyl esters of JA than to its free acids.
