To study the effect of the osmotic stress in the microenvironment on the growth and metabolism of the encapsulated cells under aerobic condition, Osmo-sensitive yeast Y02724 and high-osmotic resistant yeast Hansel were used as models to explore the growth and metabolism state of the cells cultivated inalginate-chitosan-alginate(ACA) microcapsules.

Cascade mechanism of signal transduction in plants responding to osmotic stress;

Effect of osmotic stress on contents of polyamines in flue-cured tobacco leaves under different supplying level of potassium;

Relationship between spermidine and the activities of antioxidation enzymes in leaves of wheat seedlings under osmotic stress;

Effects of chlorophyll content and POD activity on osmosis stress at seedling stage of maize hybrids;

Glands structure of liquorice and its regulation mechanism on osmosis stress

treated with osmosis stress.

The result showed that SOD,CAT activity declined and MDA content increased in the blade of the wheat after PEG6000 stress.

The analysis of resistance to salt and drought-stress on LEA_3-transgenic rice showed that the seeding height,root length,water conservation of isolated leaf,content of chlorophyll,content of dissolvent sugar,content of protein and activity of SOD of transgenic rice are higher than the control plants under the same stress condition.
