The cold-stress responsive gene DREB1A involved in low-temperature tolerance in Xinjiang wild walnut.

ABSTRACT:

Background

Low-temperatures have the potential to be a serious problem for plants and can negatively affect the normal growth and development of walnuts. DREB1/CBF (Dehydration Responsive Element Binding Protein 1/C-repeat Binding Factor), one of the most direct transcription factors in response to low-temperature stress, may improve the resistance of plants to low-temperatures by regulating their functional genes. However, few studies have been conducted in walnut. The Xinjiang wild walnut is a rare wild plant found in China, with a large number of excellent trait genes, and is hardier than cultivated walnuts in Xinjiang.

Methods

In this work, we identified all of the DREB1 members from the walnut genome and analyzed their expression levels in different tissues and during l
