Plant defense responses against penetration or colonization of pathogens are mediated by activation and repression of a large array of genes. Host endogenous small RNAs are essential in gene expression reprogramming process. We identified a new Arabidopsis micro RNA（mi RNA） ath-mi R38-3P by high-throughput sequencing and further confirmed it by Northern blot assay. Interestingly, ath-miR38-3P was highly induced after infection of the pathogen Sclerotinia sclerotiorum. Further analysis based on the mi RNA target database demonstrated that ath-mi R38-3P might target to five putative genes： AT2G03140, AT5G59430, AT5G66320, AT1G36620 and AT3G03820. To confirm the target, we conducted the quantitative real-time PCR to observe the expression pattern of each candidate gene. The results showed that only AT3G03820 was down-regulated after inoculation of S. sclerotiorum. In addition, overexpression of ath-miR38-3P down-regulates AT3G03820, suggesting AT3G03820 might represent the target for ath-mi R38-3P. Our results may provide the useful information for further studying the biological function of a novel ath-mi R38-3P and its targets in Arabidopsis-Sclerotinia interaction.

Trehalose plays an important role in protecting organisms from various stresses. Trehalose-6-phosphate synthase （TPS） is the key enzyme in trehalose synthesis, but in insects only a few TPS genes have been identified and their function has not been well characterized. To better understand the function of TPS in insects, a complete TPS complementary DNA （eDNA） clone was obtained from the fat body of the locust Locusta migratoria manilensis （GenBank accession number： EU131894）. The full-length cDNA is 2 806 bp, including an open reading frame of 2 442 bp, which encodes an 813 amino acids protein with a calculated molecular weight of 91 976 Daltons and an isoelectric point of 6.14. The deduced amino acid sequence is highly similar to other published insect TPS and its C-terminal also has a region homologous to trehalose phosphate phsophatase （TPP）. Semi-quantitative analysis indicated that the TPS transcript was expressed not only in fat body, but also in gut, hemolymph and leg muscle. These data may facilitate studies of TPS function in insects and improve our understanding of trehalose metabolism.

The objective of the present study was to develop a computer software for simulating the temporal development of plant disease epidemics using Richards, logistic, Gompertz, monomolecular, and exponential functions, respectively, and for predicting disease with a fitted model. The software was programmed using Visual Basic （VB6.0） and packaged with the Wise Installation System. The Fibonacci （＇0.618＇） section strategy was used to find out the most appropriate value for the shape parameter （m） in Richards function simulation through looping procedures. The software program was repeatedly tested, debugged and edited until it was run through favorably and produced ideal outputs. It was named Epitimulator based on the phrase ＇epidemic time simulator＇ and has been registered by the National Copyright Department of China （Reg. no. 2007SR18489）. It can be installed and run on personal computers with all versions of Windows operational systems. Data of disease index and survey time are keyed in or imported from Access files. The output of fitted models and related data of parameters can be pasted into Microsoft Excel worksheet or into Word document for editing as required and the simulated disease progress curves can be stored in separate graphic files. After being finally tested and completed, Epitimulator was applied to simulate the epidemic progress of corn northern leaf blight （Exserohilum turcicum） with recorded data from field surveys of corn crops and the fitted models were output. Comparison of the simulation results showed that the disease progress was always best described by Richards function, which resulted in the most accurate simulation model. Result also showed that forecast of northern leaf blight development was highly accurate by using the computed progress model from Richards function.

A survey was conducted for about 3 years to study the abundance and diversity of ectomycorrhizal fungi (EMF) in Jiangsu Province, China. The identification of the fungal species was based on the microscopic and macroscopic characteristics of their fruiting bodies. About 126 species of EMF were found in Jiangsu Province. These fungi were largely categorized into three orders (of 121 species), four families (of 96 species), and six genera (of about 86 species).
