Summary
Higher temperatures impact citrus tristeza virus (CTV) populations, altering their structure. This effect is strain-specific and depends on the host plant, influencing viral infection dynamics.
Area of Science:
- Plant pathology
- Virology
- Molecular biology
Background:
- Plant viruses often exist as mixed populations within a host.
- Viral population dynamics are critical for infection success but poorly understood.
- Temperature is known to affect individual virus particles.
Purpose of the Study:
- To investigate the influence of temperature on viral population structure.
- To determine if temperature affects citrus tristeza virus (CTV) populations.
- To assess host-dependent temperature effects on CTV strains.
Main Methods:
- Observation of citrus tristeza virus (CTV) populations.
- Experimentation under controlled temperature conditions (25°C vs. 36°C).
- Utilizing different host plants to evaluate host-dependent effects.
Main Results:
- A higher summer temperature (36°C) altered the population structure of some CTV strains.
- The observed temperature-induced changes in CTV populations were host-dependent.
- Not all CTV strains exhibited altered population structures under elevated temperatures.
Conclusions:
- Temperature can significantly influence the population dynamics and structure of plant viruses like CTV.
- Host-virus interactions mediate the impact of temperature on viral populations.
- Understanding these dynamics is crucial for managing viral diseases in agriculture.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

02:11Effects of Temperature on Free Energy
29.0K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...
