A malformation of plant stems commonly appearing as enlargement and flattening as if several stems were fused is called fasciation. Unusual growth, such as a spur on cherry fruit, can also be considered fasciation.

What is Fasciation in plants?
Fasciation is described as abnormal fusion and flattening of plant organs, usually stems, resulting in ribbon-like, coiled and contorted tissue.
What causes Fasciation in flowers?
Fasciation can be caused by hormonal imbalances in the meristematic cells of plants, which are cells where growth can occur. Fasciation can also be caused by random genetic mutation. ... General damage to a plant's growing tip and exposure to cold and frost can also cause fasciation.
Is Fasciation a mutation?
Fasciation is typically a mutation or deformity that occurs in the meristem of a plant. Meristems are where cells begin to form – similar to stem cells in humans, these cells divide and then specialize, becoming the cells that make up the leaves, stems and flowers.
How do you induce Fasciation?
Main mutants induce fasciation by causing premature differentiation of the meristematic stem cells or cell death by the loss of stem cell maintenance. Rhodococcus Fascians (R. fascians) releases methylated cytokinins (MeCKs) which mimic plant hormonal activity leading to fasciation in plants.
Why do flowers mutate?
Changes in the genetic code occur randomly and can happen when mistakes are made during cell division and replication, after exposure to radiation or certain chemicals or because of weather fluctuations such as extreme cold or heat. Insect damage or severe pruning also can cause a mutation in plants.
What causes Fasciation in tomatoes?
Why are my tomatoes growing together? A fasciation of flowers can cause two fruits to fuse and grow together. This phenomenon can occur in many different fruits. Genetics, bacteria, fungal or viral problems, the environment, and herbicide damage can cause the fasciation of plant parts.
What causes deformed leaves?
The most common plant abnormalities show up as curled or cupped leaves. Insects, mites, disease organisms, herbicides and weather events can all lead to malformation of leaf, stem, flower or fruit tissue.
What is a flattened stem?
A: The phenomenon of abnormally flattened stems is called “fasciation”. Many plants are known to occasionally produce fasciated limbs. The fasciation results from bacteria in some cases and genetic abnormalities in others.
Can plants have deformities?
We occasionally have plants submitted to the lab with a weird plant deformity known as fasciation. Fasciation is a term that describes the abnormal fusion and flattening of plant organs, usually stems, resulting in ribbon-like, coiled and contorted tissue.
What causes Monstrose cactus?
The crested and monstrose forms generally occur because of injuries to the plant at a young age. This damage can result from insects munching on the growing tip, or from other causes, including disease and genetic predisposition. ... Plants can exhibit mutated and regular growth at the same time.
What causes crested cactus?
Cristate or “crested” saguaros form when the cells in the growing stem begin to divide outward, rather than in the cir- cular pattern of a normal cactus. This is an unusual mutation which results in the growth of a large fan-shaped crest at the growing tip of a saguaro's main stem or arms.
