Exposure of Arabidopsis thaliana to hypobaric environments: implications for low-pressure bioregenerative life support systems for human exploration missions and terraforming on Mars.
Jeffrey T. Richards,Kenneth A. Corey,Anna-Lisa Paul,Robert J. Ferl,Raymond M. Wheeler,Andrew C. Schuerger +5 more
TL;DR: Results support the conclusions that hypobaric plant growth modules might be operated around 10 k Pa without undue inhibition of photosynthesis and terraforming efforts on Mars might require a surface pressure of at least 10 kPa (100 mb) for normal growth of deployed plant species.

Separating the effects of hypobaria and hypoxia on lettuce : growth and gas exchange
TL;DR: It is concluded that lettuce can be grown under subambient pressure ( congruent with25% of normal earth ambient total pressure) without adverse effects on plant growth or gas exchange, and hypobaric plants were more resistant to hypoxic conditions that reduced gas exchange and plant growth.

Photosynthesis and respiration of a wheat stand at reduced atmospheric pressure and reduced oxygen.
TL;DR: A 34-day functional test was conducted to determine responses of a wheat stand to reduced pressure and modified partial pressures of carbon dioxide and oxygen, suggesting that normal rhizosphere and canopy respiration occur at atmospheric ppO2 levels as low as 11 kPa.

The biology of low atmospheric pressure -- implications for exploration mission design and advanced life support
Anna-Lisa Paul,Robert J. Ferl +1 more
TL;DR: The molecular genetic responses central to the initial exposure of the model plant Arabidopsis to hypobaric stress are identified, establishing that response to hypobaria is a unique biological response and is more complex than just an adaptation to low partial pressures of oxygen.
Journal ArticleDOI
Effect of hypobaric storage on quality, antioxidant enzyme and antioxidant capability of the Chinese bayberry fruits.
TL;DR: Hypobaric storage improved the metabolism, antioxidant system and postharvest quality of Chinese bayberry fruit and provided an effective alternative method to prolong the storage life of this fruit.

Respiration, Growth and Maintenance in Plants
TL;DR: The derivation gives a better understanding of the role of the constants k and c in McCree's equation and the relevance of dark and light respiration to the following analysis is discussed later.

Bruce Bugbee,Frank B. Salisbury +1 more
TL;DR: Wheat is physiologically and genetically capable of much higher productivity and photosynthetic efficiency than has been recorded in a field environment.

Gas Exchange Characteristics of Wheat Stands Grown in a Closed, Controlled Environment
TL;DR: Gas exchange of wheat stands grown in controlled environments will be used to model the use of plants for CO2 removal, O2 production, and water evaporation for controlled ecological life support systems proposed for extraterrestrial environments.

Growth of plants at reduced pressures: experiments in wheat-technological advantages and constraints.
Marcel Andre,D. Massimino +1 more
TL;DR: Advantages of the low pressure cultivation, especially in the absence of nitrogen, are discussed, including better ratio volume/mass of plant cultivation module; lower losses of gases by leakage; easier management of photosynthetic oxygen produced by plants.

Photosynthesis and Photorespiration in Whole Plants of Wheat
Alain Gerbaud,Marcel Andre +1 more
TL;DR: It is concluded that at a given light intensity, O( 2) and CO(2) compete for the reducing power produced at constant rate by the light reactions of photosynthesis.
