Frost-free zone on leaves revisited
1Department of Environmental Sciences, University of Basel, Basel 4056, Switzerland.
Summary
Microorganisms can alter frost patterns on leaves, forming ice in grooves instead of crests. This adaptation helps them thrive in cold, arid environments by creating favorable microclimates.
Area of Science:
- Plant biology
- Microbiology
- Physics of frost formation
Background:
- Frost patterns on leaves are influenced by surface topography.
- Grooves on leaves can provide moisture niches for microorganisms in arid environments.
- Previous research by Yao et al. explained frost formation on corrugated surfaces.
Purpose of the Study:
- To investigate how microorganisms can influence frost patterns on plant leaves.
- To understand the adaptive advantage of ice nucleation by microorganisms.
- To explore the ecological role of this phenomenon in cold arid environments.
Main Methods:
- Observational studies of frost patterns on leaves.
- Microbiological analysis of leaf surfaces.
- Modeling of ice nucleation and frost formation dynamics.
Main Results:
- Certain microorganisms can nucleate ice prior to natural frost formation on leaf crests.
- This microbial activity modifies frost patterns, favoring ice formation in grooves.
- Microorganisms gain a survival advantage by controlling moisture distribution.
Conclusions:
- Microbial ice nucleation is an adaptive strategy for survival in cold arid conditions.
- This mechanism may explain the symbiotic associations between plants and specific microorganisms.
- Understanding frost-microbe interactions is crucial for plant ecology in extreme environments.

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.

01:57Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

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...
