Hybrid zones between invasive Rorippa austriaca and native R. sylvestris (Brassicaceae) in Germany: ploidy levels and patterns of fitness in the field. (1/5)
Hybrid zones may serve as natural laboratories for evolutionary studies. One common viewpoint is that hybrids may always be less fit than their parents due to genetic discontinuities. An alternative idea is that genotype-environment interactions influence the outcome of natural hybridization. Our comparative study of two different natural hybrid zones between the invasive diploid Rorippa austriaca and the native polyploid R. sylvestris in Germany identified the ploidy level as a major determinant of hybrid fitness. Different ploidy levels and patterns of fitness were detected in different hybrid zones. In one hybrid zone (Mulheim, Ruhr valley) hybrids were pentaploid and showed a relatively high seed set, whereas in the second hybrid zone (Randersacker, Main valley) hybrids were triploid and displayed extremely low fitness values. Analyses of fitness values in different natural hybrid zones between the same two species may lead to very different conclusions about the evolutionary significance of natural hybridization.

(+info)"Rorippa" is a genus of plants in the family Brassicaceae, also known as the mustard or cabbage family. These plants are often referred to as yellowcresses or water-peppers. They are found worldwide and include both aquatic and terrestrial species. Some Rorippa species may have medicinal properties, but there is no widely recognized medical definition specifically for "Rorippa."
I believe there may be some confusion in your question. "Floods" is not a medical term, but rather a natural disaster or hydrological phenomenon that occurs when a body of water overflows its banks or normal confines, causing damage to surrounding areas. If you are looking for a medical definition, perhaps you meant to ask about a different term? I would be happy to help if you could clarify your question further.
Gene Ontology (GO) is not a medical term, but rather a bioinformatics term used to describe a controlled vocabulary or ontology for describing molecular functions, biological processes, and cellular components in which genes and gene products are involved. It provides a standardized way to represent and share information about gene function across different species.
The GO ontology is organized as a directed acyclic graph (DAG), where each term has defined relationships with other terms, allowing for the representation of complex biological concepts. The GO terms can be used to describe molecular functions such as enzymatic activities or binding interactions, biological processes such as metabolic pathways or signal transduction cascades, and cellular components such as organelles or subcellular structures.
GO analysis is a common approach in bioinformatics for interpreting large-scale genomic data, such as microarray or next-generation sequencing experiments, to identify genes that are involved in specific biological processes or molecular functions of interest.
