B) Explain how the inheritance pattern shown in Figure 1 supports a role for chloroplast genes in the production of chlorophyll in the variegated plants. A) Describe how genetic information is carried in chloroplasts and mitochondria. The variegated sections on a plant may appear as stripes, spots, circles, borders and other shapes. Some plants have clearly variegated sections, whereas some variegations may appear with some blending between sections, making their variegations appear more subtle, or take over the whole appearance of the leaf. When Im not writing, I can usually be found reading, working on DIY projects, or playing with my cats. Such plants are called chimaera.

Therefore, a variegated plant would appear two-toned or multi-tonal. Its often spread by vectors like thrips and other pests that suck the sap on an affected plant, then spreading it to an unaffected one of the same species or genus.

Unlike other types, blister or reflective variegation has nothing to do with the green pigment, chlorophyll. Instable plants will enventually revert. -All chloroplasts descended from a common ancestor. Some viruses may have little or no negative effect on the infected plant. Required fields are marked *. Theyre spontaneous mutations found by people, either in their own plant collections or in the wild at some point. Several isolated haploid petite mutants and wild-type cells were mated with each other on complete media to form diploid cells.

Unfortunately the removed branch wont be able to sustain itself so trying to root it is unnecessary and will be doomed to fail if it totally lacks chlorophyll. Viral variegation is permanent.

In the next two articles, we will explain how to identify plants with stable variegation and plants with unstable variegation. Viral infection can be harmful to the plant. Google Books. ( 1) "Variegation results from a defect that makes chloroplast development unstable, since at least part of the tissues gives rise to normal chloroplasts." Wataru Sakamoto Occasionally, variegation is also caused by a viral infection in the leaves. This can be seen in both the flowering maple, Callianthe hybridum Thompsonii and the Swedish ivy, Plectranthus verticillatus Variegatus.
