The Sceptical Gardener Variegation. -segregational petite x wild type Such plants are called chimaera. -All chloroplasts descended from a common ancestor. If the mutation happens to only some cells of the plant with regular plant cells alongside cells that are unable to synthesize chlorophyll, the chimeral variegation is unstable and irregular. In variegated plants, the meristem itself is variegated and gives rise to variegated structures. Chimeral variegation is not genetic which means the seeds from a plant with chimeral variegation will not grow into a variegated plant. what would grow, - anything involving the mutation strain of suppressive would not grow but Some of the most popular houseplants have this form of variegation such as prayer plants, calathea, and Chinese evergreens. So what is variegation? University Of California. Plants with variegated colored patterns are rare, beautiful gems for any plant collection. This makes it very stable and easily propagatable.

In plants, variegation means the appearance of different coloured zones on leaves, stems, fruit or flowers. The best way to induce variegation in plants is to propagate a genetically variegated plant or the variegated parts of a plant with mutated plant cells that lack the green pigment. Many houseplants can be deliberately cultivated to have specific patterns or colorations as well. Variegation mostly appears on the margins or the center of leaves, but it can also appear in flower petals, stems, and even fruits. Chimerism occurs when different histological regions of a plant meristem, and consequently the tissues that derive from them, have different genotypes (reviewed by Kirk & Tilney-Bassett 1978; Tilney-Bassett 1986).. 2 .

You need the most variegated leaf from a node that you can find. When plants are competing for energy production and growth, a lack of chlorophyll can stunt the plant and place it at a disadvantage. Proteomic evidence for genetic epistasis: ClpR4 mutations switch leaf variegation to virescence in Arabidopsis. To some, this is highly attractive while others dont like it as much - its a personal taste. In the grand scheme of things, variegation rarely occurs in the wild but can become a mutation which stabilizes over generations; an excellent example of this is Calathea spp. The green regular forms are often already more established in culture, and they can also be tissue cultured in greater numbers faster if needed, which often isnt possible for many of the variegated plants. Chimeras may also experience this if the non-variegated leaves hold genetic dominance. There are four main types of variegation that affects plants. (n.d.).

Variegated plants also have smaller leaves, less tolerance to shady areas and yet a tendency to burn in the hot sun, and slower growth. In this case the mother is a/a so she cannot produce any normal gene products for this trait; therefore all of her offspring will be mutant (wingless). If suddenly your plant puts out several totally green or fully white leaves in the newer growth, this means that it has either reverted back to green or gone fully albino. It is caused by the Honeysuckle yellow vein virus (Valverde et al, 2012). Variegated specimens are most often propagated from parent plants with stable genetic mutations that do not revert over time.
