BIO353H5 Study Guide - Final Guide: Gynoecium, Gynophore, Vascular Bundle
Document Summary
Stage 8 gynoecium (female part of flower, looks like a little tube). Petals start forming at the base, and ridges on the tube fuse to form the septum. Notice hole in a and d, covered in g that"s where the ovules are and why it"s getting transformed. As outer thin walled valve cells (blue) dry, they are thought contract creating tension against the rigid enb (purple) and lignified valve margin (pink) layers. The color scheme is valves (blue), replum (red), septum (light orange), seeds (brown), enb layer (purple), valve margin lignified layer (pink), and. Agrobacterium-mediated transformation happens when you damage the plant, and then the bacterium"s plasmid enters the plant from the soil. This is useful because you can add new genes or whatever into the plasmid, and manipulate the growing plant"s seeds to grow desirable phenotypes you can put auxin or cytokinin in it.
