The present study was aimed to develop a solid - culture - based technology for easy and cheap propagation of p . delphacis f95129 inocula using small grains as substrate for fungal growth . sporulation capacity and timing pattern were relied upon to evaluate culture quality and identify potential factors to affect the quality . infectivity or virulence of inocula derived from the culture was assayed against the green peach aphid , myzus persicae ( sulzer ) , based on time - dose - mortality modeling 針對這一普遍性的技術難題，本研究以飛虱蟲癘霉f95129菌株為對象，以黍米、粟米為基本材料，探索建立簡便易行的侵染體繁殖技術體系，并對培養物進行了產孢潛能及其影響因子的評價以及針對桃蚜( myzuspersicae ( sulzer ) )的侵染性測定和時間?劑量?死亡率模型模擬。
However there was not significant difference with respect to the antibiotic production and sporulation from the wild type strain when hxy1 was inoculated on mmasp and r5 medium ; phz1102 , a vector with copy number about 10 in streptomyces , was transformed into j1702 and j1700 , but it ca n ' t supress the bald phenotype Hxy1在mmasp及r _ 5平板上培養時，在產素及產孢方面與野生型沒有明顯差異。將phz1102以中等拷貝轉化到j1702和j1700兩種hlda突變株中發現phz1102不能抑制它們的光禿表型。
Also the ci represser was expressed , presumably from its own phage promoter and prevented transcription from pr at low temperature . moreover , s . lividans strains expressing the c . 100 kda pks were different in sporulation and antibiotic production compared to strains without the 2 . 7 kb pks gene , suggesting that the pks protein was active in an unknown manner in streptomyces 表達pks的變鉛青鏈霉菌菌株在孢子形成和抗生素產生方面與沒有2 . 7kbpks基因的菌株相比較是有區別的，因而推測在鏈霉菌中表達的雙功能結構域pks蛋白具有活性。
Sporulation on cultures of both millet species lasted for 6 days on non - nutritional substrate at 25c and l : d 12 : 12 . compared to 2 . 3 0 . 3 x104 conidia discharged from each cadaver of myzus persicae adults killed by p . delphacis with a < 60 - h duration of sporulation , 5 . 6 - 1 a and 3 . 7 - 4 . 7 times more conidia were discharged from each of the broomcorn millets cultured for 5 - 11 days and from each of the foxtail millets cultured for 3 - 11 days , respectively , with an over doubled sporulation duration 相對于新鮮蚜尸2 . 3 0 . 3 10 ~ 4個孢子/頭的平均產孢量和60h的有效產孢時間， 5 11d黍米培養物的產孢潛能高出5 . 6 7 . 4倍， 3 11d的粟米培養物的產孢潛能則高出3 . 7 4 . 68倍，有效產孢時間均延長1倍以上。
S . lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation . it was speculated that dnda together with its downstream dna ( 2 . 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64 , while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s . lividans 1326 另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因( mel )表達方面的差異，推測dnda及其下游區域與變鉛青鏈霉菌的產孢和刺激外源黑色素基因的表達有關，而dndb和dndc則與之無關，因為la1和la2在這兩種表型上與野生型菌株無明顯差異。
The recombinant b . thuringiensis subsp . israelensis b - pmpx2 can produce a rhombus crystalline inclusion body during its sporulation sds - page analysis proved that cytlaa had overexpressed during the sporulation of the recombinant . it was found that b - pmpx2 strain remained stable toxicity , whatever during vegetative phase or sporulation phase , which was similar to the expression of mtxl gene in the strain of protease ( s ) - deficient b . sphaericus 同時，將來源于蘇云金芽孢桿菌以色列亞種( b . thuringiensissubsp . israelensis , b . t . i )的cytlaa基因和p20伴侶蛋白基因克隆連接到質粒pmt9中，并轉化到蘇云金芽孢桿菌無晶體型中得到重組轉化子b - pmpx2 ，電鏡觀察發現重組轉化子b - pmpx2形成一菱形晶體。
3 . the effect of sporulation - independent promotor on toxicity of natural strain in order to study the effect of sporulation - independent promotor ( p3a ) , p3a was spliced with the cry1c gene , then inserted into the shuttle vector pht304 , and then recombinated plasmid pbmb827 was obtained . after transferring pbmb827 into strain ybt - 1520 , it was surprising that the transformants had almost no potency against all lepidopteran larvae tested 3非依賴芽胞形成icp的cry3a啟動子( p _ ( 3a ) )對野生菌株特性的影響帶p _ ( 3a )和cry1c基因的重組質粒pbmb827轉入ybt - 1520 ，轉化子對所測昆蟲的毒力下降非常明顯，芽胞和晶體也很難脫落。
Northern blotting analysis showed that cryld mrna was more stable than crylab mrna , however , cryld mrna formed later 3h and less 3 . 7 times than crylab mrna during the mid - phase of sporulation . moreover , crylab mrna could keep stable and large amount during the post - phase of sporulation . this suggested that difference of transcriptional efficiency and initiate time might be main reason for the difference of expression of crylab and cry id 結果表明：基因cry1dmrna的形成比基因cry1ab的mrna滯后3小時，且基因cry1d形成mrna的量很低，產生過程很平穩，在芽胞形成中期比cry1abmrna低3 . 7倍； cry1abmrna含量在芽胞形成前期高于后期，在后期仍能大量持續穩定地轉錄。
Protoplast regeneration , treatment of mutagenesis and other unknown factors can increase the genomic inherent instability , which usually affects the following five phenotypic traits : sporulation , pigmentation , colony morphology , antibiotic production and antibiotic resistance 基因組的不穩定性通常會影響菌株的以下五種表型特征：產孢，產素，菌落形態，抗生素產生水平以及對相應抗生素的抗性水平。
Three different batches of broomcorn millet cultures obtained under uniform conditions in millet processing , initial inocula level , and incubation were found not significantly differing in sporulation capacity . on non - nutritional agar plates , temperature significantly affected sporulaiton 本研究用白碳黑、硅藻土和變色硅膠對新鮮黍米培養物進行處理并在5和10下保存，均導致其快速喪失產抱能力。
Sodium succinate as carbon source could lead to earlier sporulation and earlier expression of cryld - lacz , when sodium acetate acted as carbon source , cryid - lacz could keep high , stable expression in different hosts 琥珀酸鈉作碳源時導致芽胞形成提前， cry1d - lacz融合基因表達也隨之提前。而以乙酸鈉作碳源時，在不同亞種的菌株中都能高水平、持續穩定地表達。
The result shows that the life cycle of all the species comprises a unicellular amoeboid or swarm cell stage , a multinucleate plasmodium stage and a sporulation stage 結果表明，生活循環均包括單核的黏變形體或游動胞、多核的營養體原質團以及形成孢子階段。
However it is susceptible to protease ( s ) and cannot express in a large amount in the sporulation phase of natural occurring strain of b . s 但它在野生型菌株中的表達量低，易被蛋白酶降解失活。
