Discovery of cold-resistance genes in Vitis amurensis using bud-based quantitative trait locus mapping and RNA-seq.

ABSTRACT:

Background

In cold regions, low temperature is the main limiting factor affecting grape production. As an important breeding resource, V. amurensis Rupr. has played a crucial role in the discovery of genes which confer cold resistance in grapes. Thus far, many cold-resistance genes have been reported based on the study of V. amurensis. In order to identify more candidate genes related to cold resistance in V. amurensis, QTL mapping and RNA-seq was conducted based on the hybrid population and different cold-resistance cultivars in this study.

Results

In this study, highly cold-resistant grape cultivar 'Shuangyou' (SY) which belongs to V. amurensis, and cold-sensitive cultivar 'Red Globe' (RG) which belongs to Vitis vinifera L. were used to identify cold resistance genes. Cold
