Renovation Pruning of Egg Plant Culture

Renovation of the egg extracellular matrix at fertilization.

Extracellular matrices are essential for cell survival and function. This is especially relevant for eggs, which establish a physical barrier at fertilization to protect a new embryo from additional sperm and pathogens. Formation of an extracellular matrix is most dramatic in sea urchins, in which fertilization was first observed in animals with the "sudden appearance of a perfectly transparent...

Plant Culture Equipment.

A detailed description is presented in this paper of small sand and water culture equipment. A number of large out-of-doors sand cultures both for tree and annual crops have also been constructed at the U. S. Regional Salinity Laboratory, Riverside, California. In their general features these latter cultures are like those described in an earlier publication (3). The more significant modificati...

History of plant tissue culture.

Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application. It owes its origin to the ideas of the German scientist, Haberlandt, at the beginning of the twentieth century. The early studies led to root cultures, em...
