Oxidating a plant
This complexity arises as a result of a long-standing evolutionary battle in which the pathogen attempts to invade and multiply and the plant attempts to recognize and defend itself from this invasion.
The pathogen must then take steps to escape detection or to avoid triggering a response, which will prevent its entry into, or proliferation within, plant tissues.
We also explore the ways in which pseudomonads may exploit plant ROS generation for their own purposes and even produce ROS directly as part of their infection mechanisms.
The interaction between plant pathogens and their hosts is complex.
Understanding this process is crucial for the future development of clean, renewable and unlimited energy sources.
We have been focusing on the role of two lumenal proteins in the water oxidation process, Psb O and Cah3,which are associated with the thylakoid membrane.
Various methods are utilized for quantifying plant responses to reducing soil conditions that include measurement of radial oxygen transport, plant enzymatic responses, and assessment of anatomical/morphological changes.
However, the chemical properties and reducing nature of soil environment in which plant roots are grown, including oxygen demand, and other associated processes that occur in wetland soils, pose a challenge to evaluation and comparison of plant responses that are reported in the literature.
Glutathione reductase activity did not show significant changes as a result of Cd treatment.
If we can fully understand the mechanism of water oxidation and its regulation, we can use that knowledge to create artificial pho- tosynthetic devices to produce clean and renewable energy.
Plants produce oxygen that is released to the atmosphere. Photosystem II (PSII) uses sunlight to split water, an ener- getically unfavourable reaction in which electrons and protons are extracted from water and oxygen is released as a by-product.
We have known for many years how electrons are transported in the photosynthetic light reac- tions,but we have very limited information on how the protons are transported.
Protons must be transported away from the catalytic centre, otherwise the oxidation reaction cannot occur with full efficiency.
