A preliminary study on the root-knot nematode resistance of a cherry plum cultivar Mirabolano 29C

Grafting is the most important means of breeding peach, plum, apricot, and other fruit trees, selection rootstock crucial to quality grafting yield products. The traditional commonly used peach susceptible root-knot nematode infections, resulting in a decreased yield, while variety cherry plum rootstocks, Mirabolano 29C, resistant nematode. In this study, infection experiments on seedlings rootstocks 29C confirmed that was indeed more nematodes. At same time, we compared roots uninfected infected by transcriptome sequencing found 3 176 differentially expressed genes. A further functional enrichment analysis these genes secondary metabolites, phenylpropane flavonoids, may be responsible for high resistance These results can provide reference value disease rootstocks.
