Chromosomal inversion co-segregating with plum purple leaf trait and use thereof

Abstract

The present application relates to the technical field of molecular biology and plant molecular breeding, and particularly relates to a chromosome inversion co-segregated with plum flower purple leaf character and application thereof. A chromosome inversion molecular marker co-segregated with the plum flower purple leaf character of 'Meiren' plum is developed by using nucleotide sequences on both sides of the chromosome inversion breakpoint to design primers, and the marker primer sequences are shown as SEQ ID NO. 5-10. The present application explains the evolutionary relationship and source of the chromosome inversion from the genomic level, and clearly defines the genetic evolutionary relationship of the purple leaf character of 'Meiren' plum. The molecular marker provided by the present application can efficiently and accurately predict the plum flower purple leaf character, has high accuracy and remarkable effect, has high application prospect in molecular assisted breeding, and can accurately identify the purple leaf character genotype of plum flower or Prunus germplasm resources due to distant hybridization.
