Genotyping of the <Emphasis Type="Italic">SiDREB2</Emphasis> gene in worldwide foxtail millet (<Emphasis Type="Italic">Setaria italica</Emphasis> (L.) P. Beauv.) genetic resources with special attention to Indian landraces

We genotyped Setaria italica Dehydration-responsive element-binding 2 (SiDREB2) gene, which had been reported to be associated with dehydration stress tolerance, in 588 accessions of foxtail millet from various parts of Eurasia and other regions by a dCAPS marker. Of these, 480 accessions were genotyped in ribosomal DNA (rDNA), polyphenol oxidase (PPO) gene and Heading date 1 (HD1) gene in our previous studies, and 108 accessions from India were newly used in this study and genotyped in these genes in addition to the SiDREB2 gene. We compared the geographical distribution of the SiDREB2 genotypes with that of these three genes. Accessions from countries in South Asia including India and Sri Lanka were the most variable in the SiDREB2 gene followed by Korean accessions and Japanese accessions, suggesting that Indian accessions and East Asian accessions are useful as genetic resources for dehydration stress tolerance. This study also showed that although Indian accessions are not so diverse in rDNA and in transposon display markers previously studied, they are diverse in adaptive genes such as SiDREB2, PPO and HD1 genes.     

加强质量监管保护公共安全提升企业信誉我国对问题兽药实施召回制度

2004年12月上旬,农业部兽医局致函新疆天康生物技术股份有限公司,就其羊快疫、猝狙、肠毒血症三联灭活疫苗040511批效力检验不合格一事,要求该公司将已销售的此批疫苗(共计122万毫米)召回并销毁.该厂接到函后,迅即做出反应,已于去年年底前将售出疫苗全部召回并销毁.该公司对该批疫苗发生质量问题的原因进行了分析,并制定了提高该疫苗质量的整改方案和生产方案.
