Arginine feeding experiment showed that nitrogen metabolism in the s. tenebraius was obviously affected by arginine through two possible ways : ( l ) pronase activity in vitro could be influnced by arginine, as a result, the catabolism of nitrogen - containing macro - molecule was promoted and the nitrogen element in the broth was increased. ( 2 ) arginine could be transformed into glutamic acid, so that the biosynthesis of apramycin was promoted
因而我們認為gln可能是安普黴素生物合成氮元素的供體。 arg添加實驗結果表明， arg可能通過兩種途徑影響黑暗鏈黴菌體內的氮代謝： （ 1 ） arg可能影響胞外蛋白酶的活性，進而促進含氮大分子物質的分解代謝，補充發酵過程中的氮素來源。The cause that causes dark skiing ulcer has a lot of, have endocrine, food, genetic factor, the one mite bug that returning bug having mite also is the main reason that causes dark skiing ulcer lives inside wool bursa and sebaceous glands, it absorbs the nutrition of wool bursa and sebaceous glands cell, discrepancy skin carries a lot of bacteria, it secretes the dead damage body of excretive material and mite bug to be able to cause the skin organize inflammation to cause dark skiing ulcer
引起暗瘡的原因有很多，有內分泌、飲食、遺傳的因素，還有蟎蟲也是引起暗瘡的重要原因之一蟎蟲生活在毛囊和皮脂腺內，它吸收毛囊和皮脂腺細胞的營養，出入皮膚帶入很多細菌，它分泌排泄的物質和蟎蟲的死亡殘體都會造成皮膚組織發炎引起暗瘡。Carrot tissue culture and plant regeneration factors including explants, medium and culture condition are combined together to study the most efficient protocol of carrot tissue culture and plant regeneration thereof. the most suitable explant is fresh hypocotyls segment and precultured hypocotyls derived from 7 - 10 day old aseptic plantlets generating in dark or in dim light, the best recipe for cullus induction and subculture is b5c ( 85 with 0. 5mg / l 6ba and 0. 5mg / l 2, 4 - d ), the ideal recipe for plant regeneration is 65 or ms free of hormone. a phytotron with a 16 / 8 h day / night cycle, at 25 is feasible for plant regeneration, and occasional exposure to sun light dramatically stimulates plant growth
建立了高效的胡蘿卜組織培養及再生體系以適于生產飲料的胡蘿卜「新黑田五寸人參」為材料，研究不同外植體、不同培養基，不同培養條件對胡蘿卜愈傷誘導及再生的影響，建立一套高效的胡蘿卜組織培養再生體系：最適于誘導愈傷的外植體是弱光或黑暗下發芽7 - 10d無菌苗下胚軸，最適合的愈傷誘導培養基和繼代培養是b _ 5c （ b _ 5 + 0 . 5mg l6ba + 0 . 5mg l2 ， 4 - d ） ，最適于植株再生的培養基為不添加任何激素的b _ 5或ms ，組織培養條件為25 、光照周期為16hr 8hr 。6. transformation system of mustard a serials of kanamycin concentration was added to optimum medium to test the explants resistance capacity of two kinds of mustard. the transformation procedures described were derived from numerous regeneration and trasformation designed to test factors that might affect shoot regeneration, which including length of co - cultivation. those producing the best result parameters were described as below : after the mustard explants were precultured on regeneration medium for 2 days. they were inoculated with agrobacterium for 20 minutes. inoculated explants were co - cultivated for 4 days and in shadow at first 2 days. then transferred to the same medium plus 30 mg / l kanamycin and 500mg / l garb. all of them were transferred to fresh medium every 2 weeks. the kan - resistant plants were regenerated
芥菜外植體高頻遺傳轉化體系的建立在最適培養基上試驗了兩類芥菜的三種外植體對卡那黴素的敏感性、預培養天數、浸菌時間等因素的影響，建立了芥菜高頻轉基因再生體系：取生長4天的芥菜子葉、下胚軸和25天的葉片在分化培養基上（ ms + ba3 . 0mg / l + naa0 . 1mg / l ）預培養2 - 3天後，投入農桿菌菌液中浸染20分鐘，在分化培養基上暗培養2天，正常條件下培養2天後，轉入抗性培養基（ ms ba3To study the biosynthetics genes of apramycin in streptomyces tenebrarius, the apramycin resistant gene was isolated by gunshot cloning firstly
