Paphiopedilum villosum var. annamense Rolfe. is the attractive pot plant characterize by its larger and beautiful flower. Wild population of that orchid are now considered to be rare in nature as a result of habitat destruction and commercial preference. Thus, it is very important that actions should be taken to conserve this orchid before it be...

Chitosan with initial molecular weight (Mw) about 193 kDa and the deacetylation degree of about 80% was irradiated by gamma rays from a Co-60 source in powder state for degradation. The results on Mw estimation by gel permeation chromatography method indicated that oligochitosan products with Mw from 3.7 to 28.9 kDa were successfully prepared by...

The suspension solution containing 10% water-insoluble β-glucan extracted from yeast cell wall was irradiated by gamma rays from a Co-60 source for degradation. The water-soluble β-glucan products with molecular weight (Mw) of about 30.5, 24.9 and 10.8 kDa were successfully prepared from the samples irradiated at the doses of 100, 200 and 300 kG...

SUMMARY Promoter is a sequence located at the 5’ end upstream of the gene, that plays a key role in gene expression. In tomato, the E8 gene is highly expressed during fruit ripening, and is controlled by E8 promoter. E8 promoter includes the cis-acting elements responding to ethylene or receiving independent signals of ethylene for fruit ripeni...
