Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere .
Bacterial soft rot on taro (Colocasia esculenta) Bacterial soft rots are caused by several types of bacteria, but most commonly by species of gram-negative bacteria, Erwinia, Pectobacterium, and Pseudomonas. It is a destructive disease of fruits, vegetables, and ornamentals found worldwide, and affects genera from nearly all the plant families.
It is a very economically important pathogen in terms of post-harvest losses, and a common cause of decay in stored fruits and vegetables. Decay caused by P. carotovora is often referred to as "bacterial soft rot" though this may also be caused by other bacteria. Most plants or plant parts can resist invasion by the bacteria, unless some type ...
A study conducted in the New York City retail market found that the majority of culls due to disease were caused by Rhizopus soft rot (approximately 2% decay in survey). [3] Anecdotal reports suggest that Rhizopus soft rot is unpredictably sporadic and generally results in heavy losses to entire shipments when it does occur.
Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli. Erwinia uses cell wall–degrading enzymes to cause soft rot.
You know how your houseplant looks lush and gorgeous, and then the next time you look at it, it’s sad and wilted or losing leaves? You might be dealing with root...
Prunus black Rot on a Black Cherry tree. Black rot is a name used for various diseases of cultivated plants caused by fungi or bacteria, producing dark brown discoloration and decay in the leaves of fruit and vegetables: A disease of the apple, pear and quince caused by a fungus (Botryosphaeria obtusa or Physalospora cydoniae)
Brown root rot disease is a destructive plant disease caused by fungi, primarily Phellinus noxius. [1] It affects a wide range of plants, including trees, shrubs, and crops, leading to root decay, poor growth, and often the death of the plant. This disease is common in tropical and subtropical regions with warm, moist climates. [2]
