Plant proteinase inhibitors (PIs), which play a potent defensive role against predators and pathogens, are natural, defense-related proteins often present in seeds and induced in certain plant tissues by herbivory or wounding. This review describes the main classes of proteinase inhibitors, the distribution and localization, general properties, the main(More)
Leaves of nine kinds of plants from three subfamily of Rosaceae were used as materials. Genetic relationship was analyzed and species were identified through studying FTIR of nine kinds of plants. Leaves mainly contain large amounts of carbohydrates, proteins, lipids, nucleic acids and other substances. The peaks of carbohydrates are mainly between 1440 and(More)
Today, In this paper, we describe a new increment maintenance algorithm, which is “increment maintenance algorithm based on multiple delta files”. It makes the smallest result sets of data warehouse loading and maintenance as real. In addition, it adopts multiple tiers infrastructure; by using data warehouse base, it links operation model(More)
By summarization of small and medium scale software development process practices to propose a CMM best practice in component-based system construction. This best practice not only ensures fast, reasonable, low cost software development process control, but also has distinct process control, can be rechecked and be understood. Adaptability adjustment is(More)
The aim is analyzing genetic reLationship and identifying varieties by detecting DNA differences of three kinds of Nicotiana tabacum L. using Fourier infrared spectrum (FTIR). Results show that DNA FTIR of three kinds of Nicotiana tabacum L. is relatively similar. They all have four obvious characteristic peaks. 1 105 cm(-1) beLongs to symmetrical(More)
