与pathogen相关的网络例句 [注：此内容来源于网络，仅供参考]

Appressoria were latent in intercellular cleft and were latent until banana fruit were harvested.The development process of conidia of Colletotrichum musae on fruit was not distinct from foliage and stalk.Two pairs of PCR primers were designed according to the two especial fragment (357bp and 206bp) of Colletotrichum musae. Banana tissue culture seedling genomic DNA, banana anthracnose pathogen genomic DNA, mango anthracnose pathogen genomic DNA, rubber anthracnose pathogen genomic DNA,watermelon anthracnose pathogen genomic DNA, banana crown rot pathogen genomic DNA, stylo anthracnose pathogen genomic DNA, watermelon Fusarium wilt pathogen genomic DNA were extracted using SDS method.

根据香蕉炭疽菌的两个特异片段(分别为357bp和206bp)，设计两对引物：采用SDS法分别提取了香蕉组培苗基因组DNA、香蕉果实炭疽菌弱致病株Z_1基因组DNA、香蕉果实炭疽菌强致病株Z_4基因组DNA、芒果炭疽菌基因组DNA、橡胶炭疽菌基因组DNA、柱花草炭疽菌基因组DNA、西瓜炭疽菌基因组DNA、香蕉冠腐病菌基因组DNA、西瓜枯萎病菌基因组DNA；以上述基因组DNA为模板对特异片段进行PCR验证，证明357bp的片段为Colletotrichum musaes所特有，可以用此片段进行香蕉果实炭疽病的分子检测试验，。

The pomegranate scab and fruiting pathogen are belonged to same pathogen and deduced the pathogen infect to pomegranate stem or limb at first and infect calyces and fruit second, the pathogen of pomegranate stem rot mainly infect stem or limb, whether the pathogen infect fruit and produce symptom or...

结果表明：石榴疮痂病与石榴果实上增生型症状的病原菌具有更近的亲缘关系，应为同一病原菌引起，推测该病原菌首先侵染石榴侵染枝干，然后侵染石榴的花萼和果实；而石榴干腐病病原菌主要侵染枝干，是否侵染果实及引起症状特征需要继续进行研究和鉴定。

The pathogen grew well on the media using glucose, sucrose, fructose, maltose, rhamnose or soluble starch as carbon sources. Galactose, xylose, mannite or sorbose was not beneficial for the growth of the pathogen, however. The media with only organic or inorganic nitrogen sources were not suitable for the pathogen growth although organic nitrogen sources were better than inorganic nitrogen sources. The pathogen could also infect Allium cepa L., A. fistulosum L. and A. odorum L. under artificial inoculation conditions.

在碳源中，以对葡萄糖、蔗糖、果糖、麦芽糖、鼠李糖和淀粉的利用为佳，而半乳糖、山梨糖、甘露醇、木糖和菊糖不利病菌的生长；有机氮源优于无机氮源，但单独应用有机或无机氮作为营养均不适于此病菌的生长；在人工接种条件下，病菌可侵染葱、洋葱和韭等葱属植物。
