  • Wild plant genetic resources (PGR), and particularly crop wild relatives, represent a source of useful germplasm for the present and future generations. In the past, the majority of the information on PGR was based on phenotype, geographic origin, social history, and parentage. In the last decades, advances in plant science and technology have provided new insights into the study of crop gene pools; in fact, techniques derived from plant genomics can address the weaknesses inherent non-molecular methods. The development of DNA markers and sequencing has provided new powerful ways of assessing genetic relationships and diversity, performing comparative linkage analysis, isolating useful genes from crop wild relatives, etc. Within this frame, some programs have been started at the Institute of Plant Genetics, in order to investigate the presence of gene variants in some crop gene pools, also in the view of isolating possible alleles that can be useful in plant breeding and/or in the development of new molecules. Examples are given on trypsin inhibitors isolated in the gene pool of lentil and in some cultivated and wild species of the Brassicaceae. Results indicate that in some crop wild relatives, a reasonable level of variation in active site region and/or in other important sites of the aminoacid sequence of these inhibitors can be observed. These findings might have important applications since these molecules are involved in plant disease resistance and/or can inhibit cancer cell development in vitro. Another project concerns the study of a gene family in Cynara involved in the synthesis of phenylpropanoids, which are attributed immunostimulating and antibacterial properties; in addition these molecules are reported to show anti-tumoral activity. These examples indicate that wild PGR may play an important role in developing new pharmaceutical or nutraceutical products. In this view, agricultural plants can be considered as not merely a source of food but also as bioreactors for strengthening the well-being of men. (literal)
