Im Gegensatz zu Pflanzenarten die als Modelle für die Grundlagenforschung genutzt werden oder den wichtigsten landwirtschaftlichen Kulturpflanzen hat die Züchtungsforschung an Zierpflanzen mit einer Reihe von spezifischen ...

The Rdr1 gene confers resistance to black spot in roses and belongs to a large TNL gene family, which is organized in two major clusters at the distal end of chromosome 1. We used the recently available chromosome scale ...

Using Brillouin light scattering spectroscopy as a non-destructive, label-free method to determine the effects on leave biomechanics after inoculation of Diplocarpon rosea in two different resistive rose genotypes.

The detection of QTL by association genetics depends on the genetic architecture of the trait under study, the size and structure of the investigated population and the availability of phenotypic and marker data of sufficient ...

Background: Black spot is one of the most severe and damaging diseases of garden roses. We present the draft genome sequence of its causative agent Diplocarpon rosae as a working tool to generate molecular markers and to ...

Background: The resistance of plants to pathogens relies on two lines of defense: a basal defense response and a pathogen-specific system, in which resistance (R) genes induce defense reactions after detection of ...

In a diversity panel of 96 rose genotypes, variation in the capacity to form calluses on leaf explants in vitro was investigated, and a genome-wide association study (GWAS) was performed to identify genetic factors associated ...

Petal color is one of the key characteristics determining the attractiveness and therefore the commercial value of an ornamental crop. Here, we present the first genome-wide association study for the important ornamental ...

Rose propagation by cuttings is limited by substantial genotypic differences in adventitious root formation. To identify possible genetic factors causing these differences and to develop a marker for marker-assisted selection ...

Background: Gene expression studies are a prerequisite for understanding the biological function of genes. Because of its high sensitivity and easy use, quantitative PCR (qPCR) has become the gold standard for gene expression ...
