Faba bean (Vicia faba L.) is a major food source and fodder legume, popularly known for its high content of seed-protein. Its role is critical in crop rotation, and for fixing nitrogen effectively. Polymorphic simple sequence repeat markers from transcript sequences (cDNA; simple sequence repeat [SSR]) were developed for faba bean (Vicia faba). We found(More)
The 16S rRNA gene sequences for 34 strains, including 11 isolates, were determined to classify scab-causing Streptomyces spp. and relatives isolated from potato scab lesions collected in Jeju, Korea. The 16S-23S rDNA internally transcribed spacer (ITS) sequences were determined to investigate whether the 16S-23S ITS region is useful for analysing intra- and(More)
This study investigated the tolerance to desiccation and freezing of tea seeds, embryonic axes (EAs) and cotyledonary embryonic axes (CEAs, consisting of EAs with portions of cotyledons still attached). No seeds germinated after desiccation and cryopreservation. EAs extracted from seeds desiccated to 18.9% moisture content (fresh weight basis) and(More)
This paper investigates the effect of the origin and size of the explants employed and of the preconditioning (cold acclimation, preculture) and loading treatments on survival and regeneration of cryopreserved garlic shoot apices using vitrification with the PVS3 vitrification solution. Both the origin and size of explants had a significant effect on(More)
Transcriptomes from high-throughput sequencing technology provide a good resource for molecular markers. Here, we report the development of polymorphic simple sequence repeat (SSR) markers from transcript sequences via 454 pyrosequencing for Vicia sativa subsp. nigra (narrow-leaved vetch). In contrast to V. sativa subsp. sativa, the most commonly grown(More)
Changes in moisture content (MC), sucrose and glycerol concentration in garlic shoot tips were monitored during loading and unloading with PVS3 solution. Upon PVS3 treatment, shoot tip MC decreased rapidly and sucrose and glycerol concentrations increased rapidly during the first 30 min. Sucrose and glycerol concentrations increased more slowly thereafter.(More)
In this paper, the evolution of dimethylsulfoxide (DMSO) concentration and moisture content (MC) of garlic shoot tips was studied during the course of a vitrification protocol using the PVS2 vitrification solution. DMSO concentration of shoot tips increased rapidly, reaching 34.1 mg per g fresh weight after 20 min of PVS2 treatment and remained stable(More)
This paper investigates the effect of dehydration, rewarming, unloading and regrowth conditions and of bulb post-harvest storage duration on survival and regeneration of cryopreserved garlic shoot tips. PVS3 was the most effective of the seven vitrification solutions compared. Treating shoot tips with PVS3 for 150-180 min ensured 92 % regeneration after(More)
Pseudomonas syringae pv. phaseolicola, the causative agent of halo blight, is the most important bacterial pathogen of bean. Both nontoxigenic (Tox(-)) and toxigenic (Tox+) strains of this pathogen cause halo blight in beans. However, nontoxigenic strains cannot be detected by currently available molecular and serological tools. In this study, a TaqMan(More)
Dill (Anethum graveolens L.) leaf, seed and their essential oil are rich source of antioxidants. The plant is native in Southwest Asia and is cultivated in Europe, India and the United States. This study evaluated the genetic diversity structure of 135 accessions of A. graveolens from different continents, based on random amplified polymorphic DNA (RAPD)(More)
