Elucidating the role of matrix stiffness
Therefore, soil monitoring and understanding changes in soil ecosystem are considered to be important aspects of any environmental monitoring.The recent emergence of Wireless Biosensor Networks (WBNs) promises addressing many ecological questions, particularly related to soil, though providing uninterrupted real-time data from various biosensors using RF signals.This preferential endothelial adhesivity on softer and stiffer matrices was consistent with a significant increase in α-actinin-4-associated endothelial ICAM-1 clustering, a key determinant of monocyte–EC adhesion.Further, the enhanced ICAM-1 clustering on soft and stiff matrices correlated strongly with an increase in Rho activity and ROCK2 expression.The transformed plants were selected through kanamycin resistance and grown till T3 (third transgenic) generation.
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.
These studies will open doors for use of transgenic plants to clean up environments.

To achieve this goal we genetically transformed Arabidopsis thaliana with an ACS (Aminocyclopropane-1-carboxylic acid synthase) gene.
Using quantitative real-time PCR (q PCR), we previously confirmed that the ACS gene was upregulated in poplar (Populus trichocarpa) plants when exposed to environmental pollutants including ozone and methyl vinyl ketone.
