What is sporulation and germination?

Spore is metabolically dormant structure produced during unfavorable condition by the process called sporulation. Sporulation occur during late log phase or early stationary phase. Under favorable condition spores germinate to give vegetative cell.

What is germination of spores?

Spore germination, as defined as those events that result in the loss of the spore-specific properties, is an essentially biophysical process. It occurs without any need for new macromolecular synthesis, so the apparatus required is already present in the mature dormant spore.

What is spore explain process of sporulation?

The formation of nearly asleep and inactive forms of bacteria is known as Sporulation. Spores can preserve the bacteria’s genetic material when the conditions are harsh and difficult for the normal form of bacteria. Sporulation provides a multilayered structure that can be maintained for a long time.

What are the stages of spore germination?

This revival process is classically divided into two major consecutive phases: (1) germination, during which the spore undergoes rehydration, release of dipicolinic acid (DPA), cortex hydrolysis, and coat disassembly (this phase is accompanied by transition from a phase-bright spore to a phase-dark cell, as manifested …

What is sporulation example?

They are thick-walled spores produced directly from hyphal cells. They may be terminal or intercalary. They store reserve food material and are capable of withstanding long unfavourable conditions. For example, Rhizopus, Agaricus (mushroom), etc.

What is sporulation and examples?

What phase does sporulation occur?

Sporulation is triggered after cells enter the stationary phase in a medium that supports sporulation, and it takes about 8 to 10 h to be completed (13, 14). Central to the decision to enter sporulation is the activation, by phosphorylation, of the response regulator Spo0A.

Is sporulation a reproductive process?

Complete answer: The spore of bacteria is formed in response to adverse conditions and constitutes a durable form with minimal metabolism which can usually survive starvation as it is formed from the original cell and no new cell is formed it is not considered reproduction.

What is sporulation Wikipedia?

Sporulation is the last-ditch response to starvation and is suppressed until alternative responses prove inadequate. Even then, certain conditions must be met such as chromosome integrity, the state of chromosomal replication, and the functioning of the Krebs cycle.

What is process of germination?

The process of seed germination includes the following five changes or steps: imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling.
