Plant Responses to Environmental Abiotic Stresses
The research of my group focuses on the development of biofilter made
of dried biomass of the water fern Azolla and its application for heavy
metal removal. We currently apply the biofilter for radioactive metal
biosorption, jointly with Soreq Nuclear Center. In a pilot plant we
demonstrate binding of Cobalt and Cesium from the final wastes of the
reactor. Mechanism of metal binding is analyzed by scanning electron
microscopy localizing metal binding groups. A 10KD metal, binding
peptide has been sequenced and characterized. Lately we found that
Cadmium, Mercury, Cobalt and Molybdenum are actively taken up by the
water lily Nymphae and accumulate in roots petioles and blades
Phytoremediation of industrial sludges by the Nymphae is being
developed for polluted sludge in Haifa Bay
We study stress tolerance to NaCl in Halomonas as a model system
of osmoregulation by glycinebetaine. Tolerance to oxidative stress in
beans responding to high light and iron nutrition involved enhanced
chloroplast antioxidative components: Cu Zn SOD, ascorbate, ascorbate
peroxidase, GSH and GSH-reductase
