Emerging technologies for non-invasive quantification of physiological oxygen transport in plants
Oxygen plays a critical role in plant metabolism, stress response/signaling, and adaptation to environmental changes (Lambers and Colmer, Plant Soil 274:7–15, 2005; Pitzschke et al., Antioxid Redox Signal 8:1757–1764, 2006; Van Breusegem et al., Plant Sci 161:405–414, 2001). Reactive oxygen spe...

Summary: | Oxygen plays a critical role in plant metabolism,
stress response/signaling, and adaptation to environmental
changes (Lambers and Colmer, Plant Soil
274:7–15, 2005; Pitzschke et al., Antioxid Redox Signal
8:1757–1764, 2006; Van Breusegem et al., Plant Sci
161:405–414, 2001). Reactive oxygen species (ROS), byproducts
of various metabolic pathways in which oxygen is
a key molecule, are produced during adaptation responses
to environmental stress. While much is known about plant
adaptation to stress (e.g., detoxifying enzymes, antioxidant
production), the link between ROS metabolism, O2 transport,
and stress response mechanisms is unknown. Thus,
non-invasive technologies for measuring O2 are critical for
understanding the link between physiological O2 transport
and ROS signaling. New non-invasive technologies allow real-time measurement of O2 at the single cell and even
organelle levels. This review briefly summarizes currently
available (i.e., mainstream) technologies for measuring O2
and then introduces emerging technologies for measuring
O2. Advanced techniques that provide the ability to noninvasively
(i.e., non-destructively) measure O2 are highlighted.
In the near future, these non-invasive sensors will
facilitate novel experimentation that will allow plant physiologists
to ask new hypothesis-driven research questions
aimed at improving our understanding of physiological O2
