A bHLH transcription activator regulates defense signaling by nucleo-cytosolic trafficking in rice.

Crosstalk between plant hormone signaling pathways is vital for controlling the immune response during pathogen invasion. Salicylic acid (SA) and jasmonic acid (JA) often play important but antagonistic roles in the immune responses of higher plants. Here, we identify a basic helix-loop-helix transcription activator, OsbHLH6, which confers disease resistance in rice by regulating SA and JA signaling via nucleo-cytosolic trafficking in rice (Oryza sativa).

[Analysis of XRD Spectral Structure and Carbonization of the Biochar Preparation].

XRD spectroscopy is an important means of research material inside the crystalline structure of the material. In this study it was analyzed with X-ray sources in terms of manner of preparation of different materials carbon crystal structure of biological characteristics and charring mechanism. The results showed that: Biochar contain d101 and d002 crystal face diffraction peak of carbon graphite-like microcrystalline cellulose, but after charring precipitated salt with different materials, and have a big difference, such as ox dung, castor dregs and furfural dregs of CaCO3 carbon content than other organisms, but only ox dung and castor dregs containing CaMg (CO3)2.

[Research on characteristics of soil clay mineral evolution in paddy field and dry land by XRD spectrum].

The present paper took the typical saline-alkali soil in Jilin province as study object, and determinated the soil clay mineral composition characteristics of soil in paddy field and dry land. Then XRD spectrum was used to analyze the evolutionary mechanism of clay mineral in the two kinds of soil. The results showed that the physical and chemical properties of soil in paddy field were better than those in dry land, and paddy field would promote the weathering of mineral particles in saline-alkali soil and enhance the silt content.

[Study on structural properties of biochar under different materials and carbonized by FTIR].

Infrared spectroscopy (IR) is an important means of seeing the characteristics of the structural properties. Fourier transform infrared spectroscopy (FTIR) was applied to analyze the structural properties of biochar from different materials with different methods. The results showed that: the biochars have IR absorption peaks of hydroxyls group, aromatic group and containing organic group with the activated? charcoal, but in other absorption peaks, with a significant difference.
