Overview of the status quo of traditional Indian medicine intellectual property rights protection / 国际中医中药杂志

India is rich of traditional medicine knowledge. Due to inadequate protection on its traditional medicine knowledge, some of them have been illegally possessed or used by other countries, resulting in huge economic and cultural losses. In order to prevent such issues from happening, the Indian government has formulated a series of policies to protect and rationally develop traditional medicine knowledge, taken up many effective measures, such as collecting and archiving traditional medical knowledge, formulating laws and policies, establishing an administrative supervision system for traditional medicine knowledge, establish a Traditional Knowledge Digital Library (TKDL), as well as build a traditional medical knowledge registration and invention patent system. It also establishes an investment foundation, and conducts intellectual property culture building. At present, India has formed a relatively complete protection system for traditional medicine knowledge, which has achieved good results and gained recognition. To summarize the experience of traditional medicine knowledge protection in India can provide reference for China.

Studies on the Mutation Effects of Spaceflight Treatment on Tomato / 航天医学与医学工程

Objective To select excellent tomato mutants by space treatment and to cultivate directly new varieties for production application and good seed resource.Methods Seeds of tomato cultivar were carried into space by scientific experiment recoverable satellite.The main agricultural characters of tomato mutant were observed and analyzed.Results Seeds of determinate growth habit tomato cultivar T10-3-2 were carried into space in 2002 by a recoverable satellite(Shenzhou 4).After cultivation and selection,two tomato variants(H1 and H2) and their offspring populations were obtained in SP2.Variations included quantitative character variations such as maturity,fruit characters and fruit trait,as well as genetic character variations such as changes from determinate growth to indeterminate growth of plant growth habits,and from the no shoulders to the green shoulders of fruits.These two kinds of changes were dominant mutations,and could inherit stably.The research also indicated that variations(amplitude,standard deviation and coefficient of variation) of each generation of two mutants,reduced along with generation increasing.It was showed these characters to be easily stable.Conclusion Tomato seeds loaded on spacecraft can truly form the tomato character variation,and the variation character may be stably inherited.

RAPD and SCAR Markers Analysis on the Indeterminate Growth Mutant of Tomato Derived by Space Mutagenesis / 航天医学与医学工程

Objective To evaluate the indeterminate growth mutant of tomato derived by space mutagenesis to provide the basis for selecting and cultivating the molecular markers of tomato growth habit. Methods Fifty 10-mer randomly amplified polymorphic DNA(RAPD) primers were used to examine the polymorphism of M1 and 10-3-2. Their polymorphic fragments were cloned, and then were transferred to SCAR markers. Results Of all the 50 10-mer RAPD primers, 44 primers amplified polymerase chain reaction(PCR) products and 2 primers (S165 and S168) amplified stable reproducible polymorphic products. The molecular weight of the specific amplified products were 300 bp and 1 500 bp respectively, therefore they were named as TRS165300 and TRS1681500 temporarily. And TRS1681500 was transferred into stable sequence characterized amplified region(SCAR) marker and this marker could be a specific genetic marker of this indeterminate growth habit mutant. Conclusion Space mutation can produce mutants at DNA level from the loaded materials. The indeterminate growth mutant of tomato is derived by space mutagenesis which can provide a valuable material for studying the regulation and control of tomato growth habit.

Studies on Selection and Biological Characters of Tomato Indeterminate Growth Habit Mutant Derived from Space Treatment / 航天医学与医学工程

Objective To select excellent tomato mutants by space treatment and to cultivate directively new varieties for production application.Method Growth dynamics and change of agricultural characters of the mutant of indeterminate growth habit was observed.And the enzymogram and activity of two kinds of main isoenzyme were analyzed.Result An indeterminate growth habit mutant(M1) which derived from a determinate growth habit cultivar(10-3-2) was obtained from the 1st generation after space treatment(SP_1).Being an inherited character,the indeterminate growth habit of the mutant can be expressed from generation to generation.The plant height of M1 was 145 cm,42.0 cm higher than that of the background one(increased by 29.6%),when the background plant height was determined.The main stem diameter of the mutant was 1.22 cm,0.34 cm thicker than that of background parent.However,there were no visible difference in the fruit size and fruit set percentage between them.The biological characters of M1 and its progenies were studied,and the results showed that the indeterminate growth have no side effects on the agronomic characters and fruit quality,and the mutant had a potentiality of higher yield if the condition is suitable.The activity of two enzymes,SOD and POD,was assayed and there were no obvious difference of SOD activities and enzymograms between the mutant and its background parent,but POD activity was much lower in mutant than that in its background parent.Conclusion After observation through 3 generations,it is found that indetermination growth habit is inheritable and stable.
