Rotylenchus arsenjevi are reported for the first time in Korea. The Korean species differs slightly by having a hemispherical lip region and a slightly shorter tail than the original description (c=38.2-68.7 vs 36-41). Male was founded firstly from Korea and described. Geocenamus adakensis were collected a second time from Korea at a different locality and habitat. The measurements were compared with original description and the firstly collected specimen in Korea.

정확한 in vitro 전사가 일어날 수 있는 진딧물의 세포추출액을 제조하였다. 전사를 직접 조절할 수 있는 단백질 인자를 규명하기 위하여 전사개시점과 그의 상류에 결합하는 DNA 결합단백질을 탐색했다. 전사개시점을 포함하는 단편 A(-194/23)에는 52kDa, 50kDa, 40kDa의 단백질들이 결합했으며 전사개시점 상류의 DNA 단편 B(-393/-263)에는 52kDa, 50kDa, 40kDa의 단백질들이 결합한 반면 DNA 단편 C(-263/-195)는 53kDa단백질만이 결합했다. 그리고 이들 DNA 결합단백질들의 DNA 결합 활성에는 양이온이 요구되었다.

Fruit quality traits like heat, color and flavor are unique and important for pepper cuisines and industrial use. Pepper pigments include chlorophyll, carotenoids, anthocyanin and red pigments like capsanthin are unique carotenoids to capsicum spp. So developing carotenoids-rich peppers and use of red pigments extraction along with capsaicinoids are one of interest pepper breeding goals in the world. Horticultural traits of 113 germplasms introduced by international cooperative research with YASS of China were evaluated to select promissing materials for high quality peppers during the past 3 years. All of germplasms including 60 local peppers were belong to C. annuum and fruit characteristics were diverse. Especially fruit chemical compositions like ASTA color, capsaicinoids and sugars were evaluated compared with korean commercial peppers. Average contents of ASTA　color was 98±37, 55±63mg in capsaicinoids and 12±6% in total sugars. ASTA color which generally means red pigments content was over 120 in 25 germplasms including over 200 in 2 germplasms. Higher ASTA colors were observed in different fruit types. Capsaicinoids content was over 90mg/100g in 24 germplasms including 5 germpalsms over 200mg. Especially higher capsaicinoids were higher in local peppers with round and wrinkled fruit shape. And total sugar content was over 20% in 10 germplasms. Germplasms of different fruit shapes and characteristics will be useful materials for diverse fruit quality breeding.
