Genome-Wide Analysis of Snapdragon WRKY and VQ Gene Families and Their Expression in Response to Drought and Cold Stresses

Snapdragon (Antirrhinum majus) is one of the most widely cultivated grass flowers in world. WRKY transcription factors, VQ proteins and their interactions play crucial roles plant response to abiotic stresses. However, little known about gene families snapdragon. In present study, genes were comprehensively analyzed snapdragon using bioinformatics approaches, expression drought cold stresses was examined real-time PCR. A total 67 AmWRKY identified snapdragon, which classified into different groups or subgroups based on phylogenetic analysis. Members same group sub-groups exhibited similar exon-intron structure conserved motifs distribution. Among these genes, 16 22 found differentially express under stresses, respectively. 32 AmVQ identified, 10 18 The WRKY-VQ WRKY-WRKY interaction relationships predicted for 11 cold-responsive suggesting that they might exist pathway stress. These results lay a foundation further studies regulating responses
