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(More)
The Cucurbitaceae includes important crops such as cucumber, melon, watermelon, squash and pumpkin. However, few genetic and genomic resources are available for plant improvement. Some cucurbit species such as cucumber have a narrow genetic base, which impedes construction of saturated molecular linkage maps. We report herein the development of highly(More)
Ethylene responsive factors (ERFs) are important plant-specific transcription factors, some of which have been demonstrated to interact with the ethylene-responsive GCC box and the dehydration-responsive element (DRE); however, data on the roles of ERF proteins in connection with various signaling pathways are limited. In this research, we used the GCC box,(More)
WRKY proteins are a large family of transcriptional regulators in higher plant. They are involved in many biological processes, such as plant development, metabolism, and responses to biotic and abiotic stresses. Prior to the present study, only one full-length cucumber WRKY protein had been reported. The recent publication of the draft genome sequence of(More)
Most fruits in our daily diet are the products of domestication and breeding. Here we report a map of genome variation for a major fruit that encompasses ~3.6 million variants, generated by deep resequencing of 115 cucumber lines sampled from 3,342 accessions worldwide. Comparative analysis suggests that fruit crops underwent narrower bottlenecks during(More)
A genetic map was developed with microsatellite (simple sequence repeat, SSR) markers and 148 recombinant inbred lines (RILs) derived from a cross between two cultivated cucumber (Cucumis sativus L.) inbred lines 9110Gt and 9930, which was also segregating for seven horticulturally important traits including bitterfree foliage (bi), gynoecious sex(More)
OBJECTIVE The pine wood nematode (PWN), Bursaphlenchus xylophilus, which collaborates with its associated bacteria to form ecosystem and has interaction among them, is the pathogen of pine wilt disease. This study focused on revealing the bacterial diversity of ecosystem of pine wood nematode and its associated bacteria. METHODS The metagenome of(More)
The new CaSn gene belonging to the snakin family in pepper (Capsicum annuum) encodes a novel antimicrobial peptide and responds to root-knot nematode (Meloidogyne spp.) infection. CaSn was isolated and cloned using suppression subtractive hybridization (SSH), and the gene was characterized and expressed in Escherichia coli. The CaSnakin protein encoded by(More)
Late blight (Phytophthora infestans) can have devastating effects on tomato production over the whole world. Most of the commercial cultivars of tomato, Solanum lycopersicum, are susceptible. Qualitative and quantitative resistance has been described in wild relatives of tomato. In general qualitative resistance can more easily be overcome by newly evolved(More)
Bursaphelenchus mucronatus is a plant–parasitic nematode widely existing in Eurasian pine forests. To analyze the diversity and role of bacteria associated with the nematode, culture-dependent and culture-independent methods were used to identify and characterize the composition of bacterial community. A total of 13 bacterial isolates were obtained from B.(More)
