Association mapping for yield traits in Paeonia rockii based on SSR markers within transcription factors of comparative transcriptome.

ABSTRACT:

Background

Allelic variation underlying the quantitative traits in plants is caused by the extremely complex regulation process. Tree peony originated in China is a peculiar ornamental, medicinal and oil woody plant. Paeonia rockii, one of tree peony species, is a precious emerging woody oil crop. However, in this valuable plant, the study of functional loci associated with yield traits has rarely been identified. Therefore, to explore the genetic architecture of 24 yield quantitative traits, the association mapping was first reported in 420 unrelated cultivated P. rockii individuals based on the next-generation sequencing (NGS) and single-molecule long-read sequencing (SMLRS).

Results

The developed 58 pairs of polymorphic expressed sequence tag-simple sequence repeat (EST-S
