본 연구에서는 감태 효소 추출물과 그것의 폴리페놀 추출물의 화장품 원료로서의 효능을 알아보기 위하여 항산화, 항당화, 미백, 항염 효과와 관련된 실험을 실시하였다. 감태 효소 추출물과 폴리페놀 추출물은 강력한 라디컬 소거능을 가지고 있으며 BSA/Glucose 시스템에서 최종당화생성물의 형성을 저해하는 항당화 활성과 타이로시네이즈 저해를 통한 우수한 미백력을 가지고 있음을 확인하였다. 또한 두 추출물 모두 세포 내에서 PGE2와 NO 생성 저해를 통한 항염 효과를 나타내었다. 이러한 결과를 종합해 볼 때, 감태 효소 추출물과 그 폴리페놀추출물은 화장품 원료로서의 응용 가능성이 있을 것으로 사료된다.

Conventional staining and fluorescence in situ hybridization (FISH) karyotypes of the non-genetically modified (GM) parental rice line, 'Nakdong' (Oryza sativa L. japonica), and its four GM rice lines, LS28 (event LS30-32-20-1), Cry1Ac1 (event C7-1-9-1), and LS28 × Cry1Ac1 (events L/C1-1-3-1 and L/C1-3-1-1) were analyzed using 5S and 45S rDNAs as probes. Both parental and transgenic lines were diploids (2n=24) with one satellite chromosome pair. The lengths of the prometaphase chromosomes ranged from 1.50 to 6.30 μm. Four submetacentric and eight metacentric pairs comprised the karyotype of 'Nakdong' and its four GM lines. One pair of 5S rDNA signals was detected near the centromeric region of chromosome g in both the parental and transgenic lines. The 45S rDNA signals were detected on the secondary constrictions of the satellite chromosome pair in both the parental and transgenic lines. There was no significant difference in chromosome size, length, and composition between 'Nakdong' and its four GM lines. This research was conducted as a preliminary study for chromosomal detection of transgenes in GM rice lines and would be useful for their breeding programs.

A new poinsettia cultivar 'Scarlet' was bred by the National Horticultural Research Institute (NHRI) in 2006. A cross was made between 'Christmas Eve', a variety with dark green leaves and dark red bracts, and 'Red Velvet', a red colored variety in 2003. 'Scarlet' was finally selected in 2006 after investigating the growth and flower characteristics from 2004 to 2006. 'Scarlet' has bright red colored and elliptic bracts and has absent or very weak intensity of rugosity between veins in bract. In comparison with the check variety, 'Red Velvet', plant height is tall, leafblade is long and narrow. Petiole is also longer than that of 'Red Velvet'. Short day response is fast and its bracts are fully colored 7 weeks after short day commencement.

A new poinsettia cultivar 'Miss Maple' was bred by the National Horticultural Research Institute (NHRI) in 2006. A cross was made between 'Sonora Red', a variety with short plant height, dark green leaves and dark red bracts, and 'Cranberry Punch', a deep pink colored variety in 2003. 'Miss Maple' was finally selected in 2006 after investigating the growth and flower characteristics from 2004 to 2006. 'Miss Maple' has light red colored and obovate bracts, and has weak intensity of rugosity between veins in bract. Fully colored transitional leaves are so deeply lobed that they resemble the leaves of maple. Plant height is shorter than that of 'Cranberry Punch', the check variety. Short day response fast and its bracts are fully colored 7 weeks after short day commencement.
