New and highly refined physiological techniques have largely replaced the descriptive methods of classical cytology originally used in the investigation of host-parasite relations (Shaw and Samborski, 1956; Samborski and ...

Plants respond to and defend themselves against a wide range of disease-causing microbes. In order to do so, massive reprogramming of cellular protein expression patterns, which underpin various defense pathways, must ...

Many mammals are social. The most basic social behaviour is when the actions of one conspecific are directed toward another, what we call the ‘dyadic interaction’. Both intrinsic and extrinsic factors may affect an ...

Ribosomal proteins (RPs), synthesized in the cytoplasm, need to be transported from the cytoplasm to the nucleolus (a nuclear compartment), where a single molecule of each RP assembles with rRNAs to form the large and small ...

Protoplasts derived from soybean SB-I suspension cell cultures were incubated in buffered osmoticum containing cationized ferritin (CF) or native ferritin (NF) to demonstrate the process of endocytosis in plant ...

The bigmouth buffalofish, Ictiobus cyprinellus (Valenciennes) is the only buffalofish occurring in Saskatchewan. The species supports at present a small and erratic commercial fishery in this province, but has been an ...

Water pollution has received increasing attention in recent years. With modern industrialization and increasing urbanization, the need for the preservation of our aquatic resources has become obvious. Shortages of water ...

The salinity at the waste management areas at potash mines is extreme. Saturated brine seeps from the tailings pile and contaminates the surrounding land killing vegetation and affecting soil structure. Conventional ...

The North Saskatchewan River is an important natural resource of the Province of Saskatchewan. Therefore, the many municipal, industrial, and recreational uses must not be impaired by any one user to the extent that the ...

Cold acclimation is a complex process where plants acquire increased freezing tolerance following exposure to low, non-freezing temperatures. Microtubules are dynamic components of the cytoskeleton that are essential for ...
