- Detection and quantification of Leveillula taurica growth in pepper leaves.
- Zheng Z1, Nonomura T, Bóka K, Matsuda Y, Visser RG, Toyoda H, Kiss L, Bai Y.Author information 1Wageningen UR Plant Breeding, Wageningen University & Research Center, Droevendaalsesteeg 1, 6708PB Wageningen, The Netherlands.AbstractLeveillula taurica is an obligate fungal pathogen that causes powdery mildew disease on a broad range of plants, including important crops such as pepper, tomato, eggplant, onion, cotton, and so on. The early stage of this disease is difficult to diagnose and the disease can easily spread unobserved; for example, in pepper and tomato production fields and greenhouses. The objective of this study was to develop a detection and quantification method of L. taurica biomass in pepper leaves with special regard to the early stages of infection. We monitored the development of the disease to time the infection process on the leaf surface as well as inside the pepper leaves. The initial and final steps of the infection taking place on the leaf surface were consecutively observed using a dissecting microscope and a scanning electron microscope. The development of the intercellular mycelium in the mesophyll was followed by light and transmission electron microscopy. A pair of L. taurica-specific primers was designed based on the internal transcribed spacer sequence of L. taurica and used in real-time polymerase chain reaction (PCR) assay to quantify the fungal DNA during infection. The specificity of this assay was confirmed by testing the primer pair with DNA from host plants and also from another powdery mildew species, Oidium neolycopersici, infecting tomato. A standard curve was obtained for absolute quantification of L. taurica biomass. In addition, we tested a relative quantification method by using a plant gene as reference and the obtained results were compared with the visual disease index scoring. The real-time PCR assay for L. taurica provides a valuable tool for detection and quantification of this pathogen in breeding activities as well in plant-microbe interaction studies.

- Isolation, characterization, and expression analysis of CmMLO2 in muskmelon.
- Cheng H1, Kong W, Hou D, Lv J, Tao X.Author information 1Institute of Vegetable, Gansu Academy of Agricultural Science, Lanzhou, 730070, China. chengjn@yeah.netAbstractThe full-length cDNA sequence of the MLO gene was cloned via SMART-RACE-PCR from muskmelon (Cucumis melo L.), and was designated as CmMLO2 (GenBank Accession No. FJ713542). The gene is 1,710 bp long and encodes a 570-amino acid peptide with a seven-transmembrane domain topology, and is a typical transmembrane protein. Localization analysis in onion epidermal cells showed that CmMLO2-GFP is localized in the plasma membrane. The expression of CmMLO2 gene was analyzed in melon leaf infected with powdery mildew using a quantitative RT-PCR and it was found that CmMLO2 was mainly expressed in melon leaves in a no-tissue-specific pattern. Moreover, CmMLO2 may play a crucial role in the pathogenesis of powdery mildew.

- Molecular cloning and expression analysis of CmMlo1 in melon.
- Cheng H1, Kun W, Liu D, Su Y, He Q.Author information 1Institute of Vegetable, Gansu Academy of Agricultural Science, Lanzhou 730070, China. ch06038@sohu.comAbstractMlo gene encodes an important transmembrane protein that is involved in biotic/abiotic stresses. Using the method of homologous, we cloned a Mlo gene from melon, named CmMlo1. The gene is 1551 bp in length, encoding 516 amino acids; it has seven-transmembrane domain topology and is a typical transmembrane protein. Localization analysis in onion epidermal cells showed that CmMlo1-GFP is localized to the plasma membrane. RT-PCR results indicated that CmMlo1 is mainly expressed in melon cotyledon and flower, with a tissue-specific distribution manner. CmMlo1 expression is not obvious under powdery mildew stress, but under cadmium stress, its expression was significantly up-regulated, indicating that CmMlo1 is possibly involved in abiotic stress.
