What causes position effect?
Position-effect variegation (PEV) results when a gene normally in euchromatin is juxtaposed with heterochromatin by rearrangement or transposition. When heterochromatin packaging spreads across the heterochromatin/euchromatin border, it causes transcriptional silencing in a stochastic pattern.
Can translocation cause variegation?
Position-effect variegation (PEV) usually occurs when a chromosomal rearrangement (an inversion, translocation, or transposition – including now transgene inserts) places a gene that is normally found in a euchromatic environment next to a broken piece of heterochromatin (Grigliatti, (1991); Henikoff, (1994)).
What is position effect in zoology?
Position effect is the effect on the expression of a gene when its location in a chromosome is changed, often by translocation. This has been well described in Drosophila with respect to eye color and is known as position effect variegation (PEV).
How does a variegated phenotype occur?
Variegations can be caused by mutations in nuclear, chloroplast or mitochondrial genes. In some plants, the green and white sectors have different genotypes, but in others they have the same (mutant) genotype.
How do you induce variegation in plants?
Without going too deep into the science of how radiation impacts the growth and development of cellular material, inducing variegation in plants is achieved by exposing rooted cuttings to high energy electromagnetic radiation in the form of gamma rays or x-rays.
Can you force a monstera to Variegate?
The chances of randomly developing a variegated Monstera are only about 1 in 100,000. This means, to get a variegated Monstera, you would have to propagate 100,000 cuttings and hope one of the cuttings develops variegation.
Can you force variegation?
Yes, in some cases it is possible to force variegation. A good example is the now frowned upon Philodendron Pink Congo. This plant is believed to be produced by chemical induction.
Can you induce variegation?
A. Variegation is not easily induced and can’t be done so at home. Best to get a cutting of a variegated plant from a friend or pass your’s on in order to keep the variegated plant love flowing.
How do you stimulate variegation?
Place the plant in full sun to encourage variegation. Variegated plants need more sun than solid green plants because they don’t have as much chlorophyll to absorb sunlight. If you’re growing a variegated plant, leave it near a sunny window or a bright spot on your property so it absorbs enough sun to stay healthy.
How do I make my variegated Monstera more white?
You can simply promote more variegation of already variegated plants by positioning your houseplants in a spot with more light. The darker the spot, the more green leave are produced. Near a window or an artificial light source is a good spot for your variegated plant to produce more variegation.
