Methods P16 genes were delivered to the T24 cells jn vitro by adenovirus vectors. Gene transfer efficiency and changes of biological specificity of T24 cells were analyzed.

Soil enzymes may be one potential soil biological index of soil quality for its sensitivity, specificity and combination property.

This paper summarizes the secretor, species specificity, biological significance, biosynthetic pathway and application in termite control of the phagostimulating pheromone in termites.
