For increasing the contents of specificfree amino acids in rice (Oryzasativa L.) cultivar, Donganbyeo, mutantcell lines resistant to growth inhibitionby 5-methyltryptophan (5MT) were selectedfrom embryo cultured callus irradiated with50 Gy of gamma rays. Two lines, M2-1and M2-2, were obtained from theregenerated plants by selfing. Thesegregation ratios of(More)
Of the 16 known biotypes of the Hessian fly [Mayetiola destructor (Say)], biotype L is recognized as being the most virulent. We have previously reported the development of near-isogenic lines (NILs) (BC3F3:4) by backcross introgression (Coker797*4/Hamlet) that differed by the presence or absence of the H21 gene on 2RL chromatin. Florescence in situ(More)
Bacterial meningitis remains a serious cause of morbidity and mortality in childhood. Epidemiologic investigations have shown variability in disease risks among different populations and races. In Korea, however, basic epidemiologic information on bacterial meningitis in children is limited. The main purpose of this study was to analyze bacteriologically(More)
The soybean Kunitz trypsin inhibitor (KTi) has several polymorphic variants. Of these, Tia and Tib, which differ by nine amino acids, are the two main types. In this study, differences in KTi proteome between Tia and Tib were investigated using three soybean cultivars and three mutant lines. Two cultivars, Baekwoon (BW) and Paldal (PD), and one mutant line,(More)
Femoral neck anteversion is the torsion of the femoral head with reference to the distal femur. Conventional methods that use cross-sectional computed tomography (CT), magnetic resonance or ultrasound images to estimate femoral anteversion have met with several problems owing to the complex, three-dimensional (3D) structure of the femur. These problems(More)
Seed development is known to involve complex physiological and molecular events. In order to gain information on the molecular events that occur in the grains of barley during kernel development, we conducted suppression subtractive hybridization (SSH) using grains of barley cv. Karl at 14 days after fertilization (DAF) as the tester and grains at 5 DAF as(More)
The Kunitz trypsin inhibitor (KTi) in soybean has several polymorphic types that are controlled by multiple alleles, which behave in a co-dominant fashion. Of these, Tia and Tib, which differ by nine amino acids, are the predominant types. In order to develop a single nucleotide amplified polymorphism (SNAP) marker for the classification of the predominant(More)

Polishing a die that has free-form surfaces is a time-consuming and tedious job, and requires a considerable amount of high-precision skill. In order to reduce the polishing time and cope with the shortage of skilled workers, a user-friendly automatic polishing system was developed in this research. The polishing system is composed of two subsystems, a(More)
