This study was carried out in collaboration with Lawrence Berkeley National Laboratory, Division of Earth Sciences.Poster #: 3 Campus: CSU Long Beach Poster Category: Agriculture/Biofuels/Environment Keywords: Arabidopsis, Senescence, Epigenetics Project Title: A TIR-NBS-LRR Class Disease Resistance Protein Mays be a Positive Regulator of Developmental Senescence in Arabidopsis thaliana Author List: Mendoza, Victor ; Undergraduate, Chemistry & Biochemistry, California State University, Long Beach, Presenting Author Brusslan, Judy; Biological Sciences, California State University, Long Beach Abstract: Leaf senescence is the final stage in leaf development in which the leaf reallocates its nutrients to growing parts of the plant.
The pollutant absorbing capacity will be tested by placing the transformed T3 plants in an environmental gas chamber where they will be exposed to various levels of pollutants.
The ability of the transformed plants to absorb pollutants will be evaluated by performing gas chromatography mass spectrometry analyses to measure pollutants in the inlet and outlet airflow in order to quantify the pollutant deposition rate.
We normalized the obtained path loss measurements as a function of distance for all frequencies to remove any offset difference due to factors such as antennas.
Our results indicate that at 0.9 GHz the received signal power level decays with distance by about 1.6 d B/cm when traveling in soil.
However, the trade off will be antenna size and its design complexity.
Our results conclude that it is critical to carefully manage signal power and understand antenna design when wireless biosensors are placed in an area with high quantity of clay content.
World Health Organization estimates that one in eight person die from air pollution.
The main objective of our study is to analyze the feasibility of genetically engineered plants to remove polluting volatile compounds from air.
These studies will open doors for use of transgenic plants to clean up environments.

In the second part of our experiment, we used regular gardening soil mostly composed of organic matter, perlite and vermiculite.
