In recent years, we get more alarming information on growing genetic erosion. According to current forecasts, by the middle of XXI century up to 60% of plant species diversity can be lost [1]. Loss of plant resources components is considered as one of factors of biosphere s ecological crisis [2]. [Pg.260]

Plants and microorganisms produce unique and diverse chemical stmctures, some of which act as immunomodulators (18—28). Of specimens used in traditional medicine, approximately 450 plant species have shown antiviral activity out of 4000 plants screened (19). Several tannins (20) exhibit strong inhibition of tumor promotion experimentally. Pretreatment of mice with small amounts of tannins for several days strongly rejected transplanted tumors. This activity has been claimed to be effected through enhancement of host-mediated antitumor activity. [Pg.33]

Mineralization and immobilization in the rhizosphere are processes that are probably suitable to enable us to estimate ecosystem performance—e.g., productivity, stability, resilience. To properly answer this question, we should understand how differences in plant species may affect below-ground subsystems and what is the functional significance of diversity of. soil organisms. [Pg.186]

The po.ssible role of a chelate reductase for iron uptake from microbial siderophores has been examined for several plant species (30,47). With certain microbial siderophores such as rhizoferrin and rhodotorulic acid, the reductase may easily cleave iron from the siderophore to allow subsequent uptake by the ferrous iron transporter. However, with the hydroxamate siderophore, ferrioxamine B, which is produced by actinomycetes and u.sed by diverse bacteria and fungi, it has been shown that the iron stress-regulated reductase is not capable... [Pg.231]

Nature is a highly innovative chemist, and we know only a small fraction of the universe of natural products. Currently, about half of the most widely prescribed drugs in the United States are either small-molecule natural products, such as penicillin, or synthetic molecules that are based on natural products but have better properties. The other half are products of the creative imagination of medicinal chemists. Nature s genetic and chemical diversity is a treasure that should not be squandered. One reason to maintain ecosystems such as rain forests intact is that less than 10% of plant species have been systematically investigated for their chemical products. Also, many microbes, insects, and other species have not been explored for useful products. [Pg.97]

In this chapter, we have looked at the properties of different expression hosts and expression systems, and considered some of the available strategies to control transgene expression and protein accumulation. When all these variations are combined, there exists a very diverse range of potential expression platforms that can be used to produce recombinant proteins. The choice depends on many factors, some intrinsic to the plant species or expression system, some dependent on the recombinant pro-... [Pg.212]
