Ploidy levels influence cold tolerance of Cyclocarya paliurus: insight into the roles of WRKY genes.

ABSTRACT: Cold stress in winter is one of the most severe abiotic stresses on plant growth and flourishing, and the selection of cold tolerant genotypes is an important strategy to ensure the safety of plant growth and development. Cyclocarya paliurus, a diclinous and versatile tree species originally in subtropical regions, has been introduced and cultivated in the warm temperate zone of China to meet the increasing market demand for its leaf yield. However, information regarding its cold tolerance remains limited. Based on the ploidy identification of tested materials, an imitation experiment was conducted to investigate the variation in freezing injury index and expression of the CpaWRKY family members in diploid and tetraploid C. paliurus seedlings. The results indicated a significant difference
