Genetic management is the most efficient component of disease control strategies. 抗病育种是控制疾病的有效方法之一。
So far, very little was known about the genetic structure of this pathogen, which has made the disease control especially the sheath blight resistance breeding a difficult task. Hence, more and more pathologists and rice breeders have paid great attention to it. 由于缺乏对水稻纹枯病菌遗传结构的了解,给该病害的防治特别是抗病育种工作带来了很大的困难,这已引起植物病理学家和水稻育种学家普遍重视。
Therefore, understanding of the potential genetic variation in the pathogen population is essential for developing effective disease control strategies. 因此,了解病原菌的群体结构,分析其变异潜能,对指导病害防控具有重要意义。
Objective To investigate the antigenicity and genetic characteristics of the variant of influenza virus H_3N_2 isolated by Baoan District Center for Disease Control and Prevention. 目的研究分离的H3N2流感病毒变异株的分子学抗原特性。
As a genetic disease, there is no effective way to cure thalassemia at present. To screen thalassemia patients and to avoid children with thalassemia-major born is the only way to control the spread of the disease. 目前尚无有效的根治方法,只能筛查地贫患者,避免重型地贫患儿的出生以控制该病的蔓延。
