What is Differential involvement of WRKY genes in abiotic stress tolerance of Dendrobium huoshanense about?

Extreme environments have adversely affected the habitats of medicinal Dendrobium species. Dendrobium huoshanense, a well-known traditional Chinese medicinal plant, is highly susceptible to abiotic stress. Evidence suggests that WRKY transcription factors play versatile roles in responding to both biotic and abiotic stressors experienced by terrestrial plants. The regulatory mechanisms underlying the stress responses of WRKY genes have been characterized for several model plants. In this study, 64 WRKY genes were identified in the D. huoshanense genome. Chromosome localization analysis showed that all the WRKY genes were anchored on the 15 pseudochromosomes, among which chromosome 5 was occupied by the highest number of WRKY genes (from DhWRKY7 to DhWRKY19), followed by chromosome 17 (from DhWRKY45 to DhWRKY53). Subcellular localization predictions indicated that most of the WRKY genes were located in the nucleus, with only a few WRKY genes localized in peroxisome, plastid, and mitochondria. Analysis of the conserved motifs and gene structure demonstrated that most genes, except for a few truncated genes, had more than two exons, and this was likely to be due to transposon insertio
