2 effects of light quality and kt on hypocotyl elongation the hypocotyl elongation of 2 - d - old etiolated seedlings was inhibited evidently under continuous light including uv - b, wl, bl, fr and rl. the inhibition effectiveness was uv - b > wl > bl > fr > rl
二、光質和kt對下胚軸伸長的影響不同光質持續照光對2天齡黃化下胚軸伸長有明顯的抑制，不同光質對伸長抑制的效應表現為uv - b wl bl fr rl 。 -
Shaking flask experiments and hplc analyses showed that 99 isolates still produced four components of avermectins b, in which the yields of avermectins b in 82 isolates were only about 0. 1 ~ 2 % of those produced by the parental strain olm73 - 12. 2 of 82 isolates were confirmed to be the correct gene replacement mutants by pcr and sequence analysis. the mutant only producing avermectins bl was not detected
搖瓶發酵和hplc分析結果表明，有99個突變株仍然產阿維菌素b的4個組分，其中82株的發酵單位很低，僅為出發菌株olm73 - 12的0 . 1 2 ，從中挑取2株經pcr擴增和測序驗證，均發生了正確的基因取代；沒有檢測到僅產b1的突變株，這表明阿維菌素b2組分的產生並不是因為阿維菌素pks上dh2的部分活性所造成。 -
4 effects of light quality and kt on anthocyanin accumulation 2 - d - old wl grown seedlings were irradiated with continuous wl, rl, fr, bl and uv - b, respectively, for 3 d and the accumulation of anthocyanin was detected
四、光質和kt對花色素苷積累的作用白光、藍光、紫外光b 、紅光和遠紅光等不同光質處理2天齡白光下生長的幼繭， 3天後測定花色素昔含量。 -
Among different light qualities wl was the most effective. the order of the effectiveness is wl > rl > bl > uv - b > fr. the ratio of ca / cb, in the seedling was also influenced by light quality
三、光質對葉綠素積累的影響不同光質對2天齡幼苗的葉綠素積累有明顯影響，促進效應的強度依次為wl rl bl uv - b fr 。 -
The results showed that light, especially bl and uv - b strongly induced the anthocyanin accumulation. rl was less effective in anthocyanin induction
結果表明，藍光和紫外光b明顯誘導幼茁花色素昔的積累：紅光的誘導效應相對較弱。 -
In this study, we attempted to construct an engineering strain producing only avermectin bl through the replacement of dna encoding dh2 - kr2 domains of the avermectin pks ( avedh2 - kr2 ) with dna encoding dh2 - kr2 domains from the pikromycin pks in s. avermitilis olm73 - 12, producing only avermectins b and no oligomycin. gene replacement vector pxl201 ( pkc1139 : : 5 ' flank + pia : dh2 - kr2 + 3 ' flank ) was used to transform 5. avermitilis olm73 - 12 protoplasts
我們以不產寡黴素而僅產阿維菌素b的工程菌olm73 - 12為出發菌株，用委內瑞拉鏈黴菌（ streptomycesvenezuelae ）中編碼pikromycinpks模塊2上完全活性的dh和酮基還原酶（ kr ）的dna區域對olm73 - 12染色體上編碼阿維菌素pks模塊2中dh和kr的區域進行取代，試圖構建僅產b1組分的基因工程菌。 -
