뿌리 방출물중 무기태질소가 체내성분 변이에 미치는 영향
소상섭(Sang Seop So),강영희(Yong Hee Kang) 한국식물학회 1979 Journal of Plant Biology Vol.22 No.1-2
In several leguminous plants such as acasia, arrowroot and bushclover, growth rate and contents of nitrogen, phosphorus and potassium in the tissues and the variation in the culture media were determined. In water culture which was free of added nutrients, nitrogen was found to be largely in the form of nitrate(NO_3-N). This NO_3-N is believed to be the result of nitrification from NH_4-N which was apparently released from the plants. From the studies of organ culture with root segments, the amount of nitrogen released and absorbed was found to be proportional to the amount added to the medium. Especially, in the N-plot, the amount of nitrogen absorbed by the tissue reached more than 90% of the amount supplied tothe medium already in early stage. On the contrary, in the nitrogen free plot, the amount of nitrogen released from the tissue was lower than the minimum level in the N-plot. The amount of total N and P in the cultured tissue was found to be influenced by the amount of nitrogen added in the medium. However, the amount of K in the tissue was not related to the nitrogen level in the medium, but rather it was influenced by the amount of added potassium. These findings present little difference in the metabolic pattern among the three species plants studied, and suggest that the woody leguminous plants have some common feature in their metabolic pattern.

도라지 ( Platycodon grandiflorum ) 뿌리조직에서 고농도 Polyacetylene 함유 모상근의 (毛狀根) 유도 및 배양
안준철 ( Jun Cheul Ahn ),소상섭 ( Sang Seop So ),( Koichiro Shimomura ),황백 ( Baik Hwang ) 한국식물학회 1995 Journal of Plant Biology Vol.38 No.4
Hairy roots of Korean balloon flower (Platycodon grandiflorum A. DC) were induced from the root tissues infected with Agrobacterium rhizogenes ATCC 15834. Growth and polyacetylene [lobetyol (1), lobetyolin (2) and lobetyolinin (3)] production of ten hairy root clones cultured in 1/4 Gamborg B5 (B5) liquid medium were determined. One selected hairy root clone (D6) grew well in hormone free-B5 liquid medium and showed maximum content of polyacetylenes at week 6 for 1 (0.375% dry wt) and at week 7 for 2 and 3 (3.030% and 0.206% dry wt, respectively) whose levels were much higher than those of the intact plant root (1: 0.019%, 2: 0.077% dry wt, 3 was not detected).
