        A Novel Pepper (Capsicum annuum L.) WRKY Gene, CaWRKY30, Is Involved in Pathogen Stress Responses

        Zheng Jingyuan,Zou Xuexiao,Mao Zhenchuan,Xie Bingyan 한국식물학회 2011 Journal of Plant Biology Vol.54 No.5

        WRKY proteins are a superfamily of transcription factors involved in many plant processes including plant defense responses to biotic and abiotic stresses. We isolated a WRKY gene from pepper during the incompatible interaction between the pepper cultivar HDA149 and Meloidogyne incognita. The full-length gene, named as CaWRKY30, has a 1,533-bp cDNA sequence and contains an open reading frame of 1,095 bp, encodes a putative polypeptide of 364 amino acids with a theoretical protein size of 41.2 kDa, and contains one WRKY domain followed by a zinc-finger motif. The genomic sequence of CaWRKY30 contains three exons and two introns. Southern blot analysis confirmed that CaWRKY30 exists as a single copy in the pepper cultivar HDA149 genome. Quantitative RT-PCR showed that CaWRKY30 is up-regulated by application of various pathogens including avirulent M. incognita, Tobacco mosaic virus, Ralstonia solanacerum,and Phytophthora capsici Leonian. Furthermore, the transcripts of CaWRKY30 were rapidly induced after treatment with phytohormones salicylic acid (SA). However, the expression of CaWRKY30 was down-regulated by virulent M. incognita and phytohormones methyl jasmonic acid (MeJA). In addition, the nuclear localization of CaWRKY30 was determined when a CaMV35s::CaWRKY30-eGFP fusion construct was expressed in onion epidermal cells. These results suggested that CaWRKY30might be involved in plant defense mechanisms against the diverse pathogen infection.

        The genome of the cucumber, Cucumis sativus L.

        Huang, Sanwen,Li, Ruiqiang,Zhang, Zhonghua,Li, Li,Gu, Xingfang,Fan, Wei,Lucas, William J,Wang, Xiaowu,Xie, Bingyan,Ni, Peixiang,Ren, Yuanyuan,Zhu, Hongmei,Li, Jun,Lin, Kui,Jin, Weiwei,Fei, Zhangjun,Li Nature Publishing Group 2009 Nature genetics Vol.41 No.12

        Cucumber is an economically important crop as well as a model system for sex determination studies and plant vascular biology. Here we report the draft genome sequence of Cucumis sativus var. sativus L., assembled using a novel combination of traditional Sanger and next-generation Illumina GA sequencing technologies to obtain 72.2-fold genome coverage. The absence of recent whole-genome duplication, along with the presence of few tandem duplications, explains the small number of genes in the cucumber. Our study establishes that five of the cucumber's seven chromosomes arose from fusions of ten ancestral chromosomes after divergence from Cucumis melo. The sequenced cucumber genome affords insight into traits such as its sex expression, disease resistance, biosynthesis of cucurbitacin and 'fresh green' odor. We also identify 686 gene clusters related to phloem function. The cucumber genome provides a valuable resource for developing elite cultivars and for studying the evolution and function of the plant vascular system.
