Abstract:

Based on experimental validation and bioinformatics,SSR analysis result were exploited from the transcriptiome of Naematelia aurantialba and seven strains. In the meantime,100 SSR were selected for primer design and experimental verification. A total of 4 268 sequences of 6 SSR types were retrieved. The main type of trinucleotide(P3)and hexanucleotide(P6),accounting for 64.20% of the total SSR number. Seven pairs of primers were obtained by verification test and analyzed. UPGMA clustering results showed that the seven N. aurantialba strains were mainly divided into three groups. At the same time,the DNA fingerprint coding of seven pairs of primers was constructed and the 14-digit molecular fingerprint database codes of seven N. aurantialba strains were obtained. In order to provide a theoretical basis for the germplasm resources identification,variety selection and molecular marker-assisted breeding of N. aurantialba.

Key words: Naematelia aurantialba, transcriptiome, SSR, mark development
