Using Functional Genomics to Identify Molecular Markers for Fire Blight Resistance (Erwinia Amylovora) in Apple (Malus)
Fire blight, caused by Erwinia amylovora (Ea), is a destructive disease of Malus (apple), Pyrus (pear) and some woody ornamentals in the rose family (Rosaceae). The goal of this project is to use a functional genomics approach to develop tools to breed fire blight resistant apples. Suppression subtractive hybridization (SSH) and cDNA-AFLP analysis were used to identify 650 expressed sequence ta...
متن کاملAnalysis of Fire Blight Shoot Infection Epidemics on Apple
Fire blight of apple (Malus × domestica Borkh.) can be found throughout the United States and many other countries and is a serious problem on trees of susceptible apple cultivars (9). Fire blight is caused by the bacterium Erwinia amylovora and occurs also on pear, quince, Rubus spp., and several other rosaceous hosts. The initial inoculum in an established orchard comes from overwintering can...
متن کاملDevelopment of the First Cisgenic Apple with Increased Resistance to Fire Blight
The generation and selection of novel fire blight resistant apple genotypes would greatly improve the management of this devastating disease, caused by Erwinia amylovora. Such resistant genotypes are currently developed by conventional breeding, but novel breeding technologies including cisgenesis could be an alternative approach. A cisgenic apple line C44.4.146 was regenerated using the cisgen...
متن کاملMapping Quantitative Trait Loci (QTL) for Resistance to Late Blight in Tomato
Late blight caused by Phytophthora infestans (Montagne, Bary) is a devastating disease of tomato worldwide. There are three known major genes, Ph-1, Ph-2, and Ph-3, conferring resistance to late blight. In addition to these three genes, it is also believed that there are additional factors or quantitative trait loci (QTL) conferring resistance to late blight. Precise molecular mapping of all th...
متن کاملInheritance of fire blight resistance in Asian Pyrus species
Since several Asian pear species are considered to be potential source of fire blight resistance, we crossed ‘Doyenné du Comice’, the susceptible European cultivar, with four Asian pear species. The aim of the study was to establish the level of resistance of each genotype and the mode of transmission of fire blight resistance to each F1 full-sib progeny. The best sources of resistance were P. ...
