Complete genome sequence of Paracidovorax avenae causing red stripe in sugarcane.

Objective: Paracidovorax avenae (Pa) is the causative agent of red stripe disease in sugarcane and belongs to the Gram-negative β-Proteobacteria. Red stripe is a major bacterial disease of sugarcane worldwide. Limited genome sequences of Pa can be used for exploring the phylogenetic and genetic diversity analysis in this pathogen at the complete genome level.

Insights into Reactive Oxygen Species Production-Scavenging System Involved in Sugarcane Response to Infection under Drought Stress.

Plants must adapt to the complex effects of several stressors brought on by global warming, which may result in interaction and superposition effects between diverse stressors. Few reports are available on how drought stress affects () infection in sugarcane ( spp. hybrids).

Sugarcane responses to two strains of differing in pathogenicity through a differential modulation of salicylic acid and reactive oxygen species.

Leaf scald caused by is one of the major bacterial diseases of sugarcane that threaten the sugar industry worldwide. Pathogenic divergence among strains of and interactions with the sugarcane host remain largely unexplored. In this study, 40 strains of from China were distributed into three distinct evolutionary groups based on multilocus sequence analysis and simple sequence repeats loci markers.

Systematic and functional analysis of non-specific lipid transfer protein family genes in sugarcane under infection and salicylic acid treatment.

Plant non-specific lipid transfer proteins (nsLTPs) are small basic proteins that play a significant regulatory role in a wide range of physiological processes. To date, no genome-wide survey and expression analysis of this gene family in sugarcane has been performed. In this study we identified the nsLTP gene family in and carried out expression profiling of in two sugarcane cultivars ( spp.

Molecular Detection and Quantification of in Juice from Symptomless Sugarcane Stalks Using a Real-Time Quantitative PCR Assay.

Leaf scald, a bacterial disease caused by (Ashby) Dowson, is a major limiting factor for sugarcane production worldwide. Accurate identification and quantification of is a prerequisite for successful management of this disease. A sensitive and robust quantitative PCR (qPCR) assay was developed in this study for detection and quantification of using TaqMan probe and primers targeting a putative adenosine triphosphate-binding cassette (ABC) transporter gene ().

Theoretical study of the geometries and decomposition energies of CO₂ on Al₁₂X: doping effect of Al₁₂X.

The adsorption and decomposition of CO₂ molecule on X-centered icosahedronal Al₁₂X clusters (doping atom X=Al, Be, Zn, Fe, Ni, Cu, B, C, Si, P) were investigated by the DFT methods of PW91 and PWC. Adsorption energies, chemisorption energies and energy barriers of physic- and chemisorptions for CO₂ were determined. It was found that the doping atoms and spin states have important influences on the Al₁₂X geometries, electronic properties and energies of the adsorption processes.

Adsorption of carbon dioxide on Al12X clusters studied by density functional theory: effect of charge and doping.

The adsorption of a CO2 molecule on neutral and charged X-centered icosahedron Al12X(±z) clusters (X = Al, Be, Zn, Ni, Cu, B, P; z = 0, 1) was investigated by the density functional PW91 and PWC methods. Optimized configurations corresponding to physisorption and chemisorption of CO2 were identified. The adsorption energies, activation barriers, and binding energies involving both the physisorption (Al12X(±z)·CO2-I) and chemisorption (Al12X(±z)·CO2-II) for CO2 were determined.

DFT studies on doping effect of Al12X: adsorption and dissociation of H2O on Al12X clusters.

The adsorption and reaction of H2O molecule on neutral X-centered icosahedronal Al12X clusters (X = Al, Mg, Zn, Ga, Ni, Fe, B, C, Si, P) were investigated by PW91, PBE, and PWC methods. Reaction energies and reaction barriers were determined. The spin states and the doped atoms have important influences on the Al12X geometries, density, electronic properties, and energy density of reaction between Al12X with a single H2O molecule.

DFT studies of the adsorption and dissociation of H₂O on the Al₁₃ cluster: origins of this reactivity and the mechanism for H₂ release.

A theoretical study of the chemisorption and dissociation pathways of water on the Al₁₃ cluster was performed using the hybrid density functional B3LYP method with the 6-311+G(d, p) basis set. The activation energies, reaction enthalpies, and Gibbs free energy of activation for the reaction were determined. Calculations revealed that the H₂O molecule is easily adsorbed onto the Al13 surface, forming adlayers.

Synthesis, characteristic and theoretical investigation of the structure, electronic properties and second-order nonlinearity of salicylaldehyde Schiff base and their derivatives.

A series of asymmetric donor-acceptor substituted salen-type Schiff-bases have been synthesized and their structures, electronic properties and second order nonlinearities were investigated by DFT methods. In order to verify the stable of these Schiff-base derivates, the IR spectrum of these Schiff-base derivates were calculated, the result showed that these compounds are stable. The results of TD-DFT calculation indicate that the derivatives with the electron-donating group (CH3, OCH3 or N(C2H5)2) have a red shift absorption compared to derivatives with the electron-withdrawing group (NO2).
