Somatic hybridization is performed to obtain significant cytoplasmic male sterility （CMS） lines, whose CMS genes are derived either from the transfer of sterile genes from the mitochondrial genome of donor parent to the counterpart of receptor or production of new sterile genes caused by mitochondrial genome recombination of the biparent during protoplast fusion. In this study, a novel male sterile line, SaNa-IA, was obtained from the somatic hybridization between Brassica napus and Sinapis alba. The normal anther development of the maintainer line, SaNa-IB, and the abortive process of SaNa-IA were described through phenotypic observations and microtome sections. The floral organ of the sterile line SaNa-IA was sterile with a shortened filament and deflated anther. No detectable pollen grains were found on the surface of the sterile anthers. Semi-thin sections indicated that SaNa-IA aborted in the pollen mother cell （PMC） stage when vacuolization of the tapetum and PMCs began. The tapetum radically elongated and became highly vacuolated, occupying the entire locule together with the vacuolated microspores. Therefore, SaNa-IA is different from other CMS lines, such as ogu CMS, pol CMS and nap CMS as shown by the abortive process of the anther.

In the course of using precise visual instrument, aiming precision is an important parameter to analyze the measurement error. Usually, instrument calibrated error is set down as measurement error. In the paper, the precision theory of TC2003 theodolite is analyzed and some aiming experiments is done for different width line. Then, the relations between the width of line and aiming precision are shown by different aiming methods of two superposition solid lines and one line clipped by double lines. Finally, an effective method to improve aiming precision is proposed which adopts the aiming method of one line clipped by double lines.

植物特异的KNOTTED-LIKE HOMEOBOX(KNOX)蛋白属于转录调控因子家族,该家族在植物生长发育过程和各种胁迫应答中发挥着重要的作用。KNOX蛋白中存在4个保守的结构域:TALE(three amino acid loop extension)类型的HD(homeodomain)、ELK结构域,以及2个亚结构域KNOX1和KNOX2。目前,甘蓝型油菜的BnKNOX基因家族还未有系统的研究报道。本研究通过生物信息学分析鉴定获得甘蓝型油菜的36个BnKNOX家族成员。通过序列比对和系统发育树分析,将其分为3个亚家族(Ⅰ、Ⅱ和M类)。进化分析表明,全基因组复制(whole genome duplication,WGD)和片段复制(segmental duplication)是BnKNOX基因家族扩张的主要动力。基于甘蓝型油菜不同发育时期组织/器官的RNA-seq分析发现,该基因家族的BnKNAT25/26/29/30在胚乳和种子发育过程中特异表达,而BnKNAT31/32/34在成熟种子中高表达。通过BnKNOX家族的顺式作用元件分析和非生物胁迫条件下的表达模式分析,本文鉴定获得17个响应干旱和渗透胁迫的BnKNOX成员。
