项目摘要
The gender of asparagus is known to be determined by a male active factor M. Some lines of asparagus cultivars carry a homozygous genotype for M. These lines are practically called supermale, since all of the progeny express male phenotype, when pollens from these lines have been used for pollinaton. Therefore, the establishment of supermale lines of asparagus has been tried, in order to produce seed populations only with male genotype. To isolate the homozygous genotype on M male asparagus plants with andromonoecous phenotype, which are able to seed by self-fertilization, have been used. However, lines with flowers capable of self-fertilization are extremely infrequent, and the establishment of supermale lines strongly depends on cultivars. Asparagus differentiate flowers initially as hermaphroditic morphology, and then mature into female and male flowers by degeneration of the inappropriate floral organ. The identity of floral organs is regulated under the expression of MADS-box genes. Flowers set on a line of 'Gold Schatz' (GS#2) form carpel-like organs at whorl 3, and the reduced expression of class-B genes was found to relate the homeotic change. In addition, floral organs at whorl 3 of 'GS#2' escape the possible degeneration and continue to develop until maturation. The progeny obtained by mating with wild-type asparagus showed only normal phenotype, suggesting that the mutation must be recessive. In future, the establishment of methodology to produce progeny showing the homeotic change may be required. On the other hand, for readily applicable research, we examined diagnostics of female and male asparagus. As a result, the utilization of DNA markers may be efficient for identifying gender of asparagus plants at the juvenile stage. Furthermore, supermale individuals were distinguishable from male individuals by quantitative PCR using the DNA markers, suggesting that supemale carries homozygous genotype on male-activating factor M.
已知芦笋的性别是由男性活性因子M确定的。一些芦笋品种携带纯合子基因型的。这些线实际上称为超级男性,因为所有后代的表达男性表型,当这些线的花序都用于花粉中。因此,已经尝试了建立芦笋的超级芦笋线,以便仅用男性基因型产生种子种群。为了分离M雄芦笋植物的纯合基因型,使用雄激素表型,可以通过自我施用来播种。然而,具有自我施用的花的线极为频繁,超级矿物线的建立很大程度上取决于品种。芦笋最初将花与雌雄同体的形态区分开,然后通过不适当的花器官退化成熟成雌花和雄花。花器的身份受到MADS-Box基因的表达调节。花上的花在“金schatz”(GS#2)的线上,形成了螺纹3的皮层状器官,发现B类基因的表达减少与同型变化有关。此外,'GS#2'的螺纹3的花器避免了可能的变性,并继续发展直到成熟。通过与野生型芦笋交配获得的后代仅显示正常表型,表明该突变必须是隐性的。将来,可能需要建立产生后代的方法论。另一方面,为了容易适用的研究,我们检查了雌性和雄性芦笋的诊断。结果,DNA标记物的利用可能有效地在少年阶段鉴定芦笋植物的性别。此外,使用DNA标记的定量PCR可以与雄性个体区分开,这表明Supemale在男性激活因子上携带纯合基因型。
