Although leaf chloroplast transformation technology was developed more than a decade ago, no reports exist of stable transformation of undeveloped plastids or other specialized plastid types, such as proplastids, etioplasts, or amyloplasts. In this work we report development of a dark-grown tobacco suspension cell model system to investigate the transformation potential of undeveloped plastids....

In vitro cell transformation assays have been proposed for predicting the carcinogenic potential of chemicals. Morphological transformation can be induced by exposing mammalian cells to carcinogens. The cellular and molecular processes involved in cell transformation in the cultures are assumed to be similar to those of in vivo carcinogenesis. BALB/c 3T3 is an established cell line transformabl...
bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. this microstructure has shown ultimate tensile strength of about 2.2 gpa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 hv and impact toughness in the range of 30 to 40 mpa m1/2. with ca...
