SOA can help organizations streamline processes so that they can do business more efficiently, and adapt to changing needs and competition, enabling the software as a service concept. eBay for example, is opening up its web services API for its online auction.
Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants.Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by consumption of plant tissues.ost bacteria that are associated with plants are actually saprotrophic, and do no harm to the plant itself. However, a small number, around 100 known species, are able to cause disease. Bacterial diseases are much more prevalent in sub-tropical and tropical regions of the world.
A plant disease is usually defined as abnormal growth and/or dysfunction of a plant. Diseases are the result of some disturbance in the normal life process of the plant. Diseases may be the result of living and/or non-living causes. Biotic diseases are caused by living organisms such as fungi, bacteria, and viruses.ven though a plant has symptoms on a specific part, it does not necessarily mean the damaged tissue contains the organism causing the symptoms. For example, a root rot can cause chlorosis and wilting of stems and leaves, BUT the disease causal organism is in the roots.
