DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

Determination of genetic differences and levels of gene expression in mature and old tissues (e.g. wood) is often difficult based on morphological and anatomical characteristics, levels of metabolites or enzymatic activity. The use of molecular markers allows assessment of polymorphic (genetic) variation amongst individuals and between closely related species directly at the DNA level, but such techniques have not been generally applied to the bark and wood of mature trees. In this study we have applied the technique of random amplification of polymorphic DNA (RAPD) by the polymerase chain reaction (PCR) to analyse the relationship between the bark and variously aged wood zones of Robinia pseudoacacia. The use of micro polyacrylamide gel electrophoresis coupled to silver staining for DNA provided a quick, reliable and sensitive method of detecting polymorphisms. It was necessary to test a small number of ten-base synthetic oligonucleotide primers before arriving at a set of five which clearly identified post-transcriptional differences between bark, sapwood, transition zone and heartwood even in the one individual tree. The variability of the technique, and in particular the origin and quality of the DNA extracted was analysed. We demonstrated that the procedures and protocols developed are applicable to all tissue types tested from bark to the inner heartwood zones. Our results show that RAPDPCR technology is a versatile and sensitive method of detecting genomic changes in trees.
