Somatic Embryo as a Tool for Micropropagating of Some Plants

Auxin is a hormone related to the elongation and regulation of plants. It also plays an important role in the establishment polarity with the plant embryo. Research has shown that the hypocotyl from both gymnosperms and angiosperms show auxin transport to the root end of the embryo. They hypothesized that the embryonic pattern is regulated by the auxin transport mechanism and the polar positioning of cells within the ovule. The importance of auxin was shown, in their resea… WebWhen the spherical embryo labeled with tracer dye or GFP-nos1 3'UTR mRNA was transplanted onto the animal part of the blastoderm in a host embryo at the blastula … Web11. okt 2012 · Comparison of early development is a powerful approach to understand how spherical embryos set up the basis for body patterning.
