DataSheet_1_Physiological and transcriptome profiling revealed defense networks during Cladosporium fulvum and tomato interaction at the early stage.docx

Tomato leaf mold caused by Cladosporium fulvum (C. fulvum) is a serious fungal disease which results in huge yield losses in tomato cultivation worldwide. In our study, we discovered that ROS (reactive oxygen species) burst was triggered by C. fulvum treatment in tomato leaves. RNA-sequencing was used to identify differentially expressed genes (DEGs) induced by C. fulvum inoculation at the early stage of invasion in susceptible tomato plants. Gene ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases were used to annotate functions of DEGs in tomato plants. Based on our comparative analysis, DEGs related to plant-pathogen interaction pathway, plant hormone signal transduction pathway and the plant phenylpropanoid pathway were further analyzed. Our results discovered that a number of core defense genes against fungal invasion were induced and plant hormone signal transduction pathways were impacted by C. fulvum inoculation. Further, our results showed that SA (salicylic acid) and ABA (abscisic acid) contents were accumulated while JA (jasmonic acid) content decreased after C. fulvum inoculation in comparison with control, and quantitative real-time PCR to detect the relative expression of genes involved in SA, ABA and JA signaling pathway further confirmed our results. Together, results will contribute to understanding the mechanisms of C. fulvum and tomato interaction in future.</p

A selective area growth double stack active layer electroabsorption modulator integrated with a distributed feedback laser

A new method for fabricating electroabsorption modulator integrated with a distributed feedback laser (EML) was proposed. With the method we fabricated a selective area growth double stack active layer EML (SAG-DSAL-EML). Through comparing with other fabrication methods of EMLs, the characters and the merits of the new method presented in this paper were discussed

The Fabrication of Eight-Channel DFB Laser Array Using Sampled Gratings

An eight-channel monolithically integrated complex-coupled distributed-feedback laser array based on sampled gratings has been designed and fabricated. Selective lasing at different wavelengths is obtained. The frequency separation between each adjacent channel is about 200 GHz. The typical threshold current is between 30 and 40 mA. The optical output power of each channel is about 10 mW at an injection current of 100 mA. The continuous tuning of emission wavelength with injected currents is also demonstrated
