More specifically, variegation results when there is a combination of mutated plant cells that are incapable of producing chlorophyll and plant cells capable of producing chlorophyll at the meristems at the shoot tips (where cell division and new leaves are formed). Using herbicides such as Round Up can cause a variegated look by interfering with the production and protection of chlorophyll (University of Minnesota, n.d). Likewise, there is some research being performed to conclude whether variegation develops as a way to prevent the plant from taking in too much sunlight as the climate grows warmer or the suns rays grow too intense for the plant. These air pockets become reflective when the light hits them, giving them a silvery appearance.

If the variegation is an induced genetic mutation, they need to be cloned asexually by stem cutting to preserve the plant tissues rather than reproduced sexually by . A comprehensive study of the leaf-variegated mutants is possible in Arabidopsis, since such mutants have been known and the cloning can be at relative ease as a model plant. This is because the white or yellow portions of the leaf lack the green pigment chlorophyll. PMC Cut away this branch to the point where its still variegated. heteroplasmic-heir cells contain both mutant and normal chloroplasts. Bookshelf [1] female parent Therefore, the leaf phenotype of the progeny plants depends only on the type of chloroplasts the female parent has; the male plant does not contribute to leaf phenotype. a+a If possible, use a vegetative propagation method (using cuttings, offshoots or division) to obtain genetically identical plants with the same leaf pattern. This method is the safest, the easiest, and is also recommended to home gardeners. Abutilon striatum: Abutilon mosaic, caused by Abutilon mosaic virus. Variegates have leaves with green, yellow or white stripes on them, which can add an interesting visual effect when planted as they sway in the wind.
