  • 摘要:populations derived from AVTO1227 and the susceptible line Money maker were used to assess the genetic mechanism underlying TYLCV resistance. We have identified a recessive TYLCV resistance gene, hereby designated as ty-5, which is linked to SlNACI. Genomic DNA pools from resistant and susceptible groups were constructed, and their genomes were resequenced. The ty-5 gene was identified on an interval encompassing the genomic positions 2.22 Mb to 3.19 Mb on tomato chromosome 4. Genotyping using linkage markers further mapped ty-5 within the interval between markers ty5-25 and ty5-29, where only the pelota gene is located. Consequently, pelota was considered as the candidate gene corresponding to ty-5. Two nucleotide transversions within the promoter region and one transversion in exon region of the pelota gene were detected in the parental lines. However, the relative transcript levels of pelota did not significantly differ among the three tomato lines, regardless of TYLCV infection. This study will facilitate marker-assisted breeding for resistance to TYLCV and lay a foundation for the research of the resistance mechanism of ty-5 in tomato.
