Tobacco Juicing Stains from Felt House Wrap?We sometimes see brown stains on foundation walls below siding on buildings where asphalt-impregnated felt or "roofing felt" was used as a moisture barrier or "house wrap" on the exterior walls, under siding. ...
We know from examining CPN-treated BY-2 cells that CPNs bind easily to plant cell walls. Therefore, the presence of cell wall material in the cultures likely depletes CPNs that could transfect protoplasts. Perhaps improved handling of protoplast preparations through further filtration or washing ...
Additional lignification was found in the axial organs of experimental plants. The deposition of lignin provided higher strength to the cell walls and an ability to bind copper ions, which protected the leaves from excesses of this metal. It is known that the lignification of cell walls is facil...
