WUSCHEL-related homebox (WOX) gene family is a type of plant specific transcription factor, and belongs to the homeobox (HB) transcription factor superfamily. WOX genes play an important role in plant development, such as stem cell regulation and reproductive progress, and have been identified in many plant species. However, the information of mungbean VrWOX genes is limited. In this study, we identified 42 VrWOX genes in mungbean genome using Arabidopsis AtWOX genes as BLAST queries. VrWOX genes are unevenly distributed on 11 mungbean chromosomes, and chromosome 7 contains the most VrWOX genes. VrWOX genes are classified into three subgroups, the ancient group, the intermediate group and the modern/WUSCHEL group, which contains 19, 12 and 11 VrWOX members, respectively. Intraspecific synteny analysis revealed 12 VrWOX duplicated gene pairs in mungbean. Mungbean and Arabidopsis thaliana have 15 orthologous genes, and mungbean and Phaseolus vulgaris have 22 orthologous genes, respectively. The gene structure and conserved motif are different among VrWOX genes, indicating their functional diversity. The promoter regions of VrWOX genes contain different number and type of cis-acting elements, and VrWOX genes show distinct expression levels in eight mungbean tissues. Our study investigated the bioinformation and expression profiles of VrWOX genes, and provided essential information for further functional characterization of VrWOX genes.

Objective:To investigate the relationship between neutrophil chemotactic function and chemokine receptor in the early stage of deep second- and third-degree burns.Methods:Twenty patients with severe burns (burn group) who received treatment within 6 hours after burns in Yantai Yeda Hospital from January 2019 to June 2020 were included in this study. Twenty healthy controls (healthy group) who concurrently received physical examination in the same hospital were also included. The general data and laboratory examination indexes in each group were analyzed. The correlation between neutrophil chemotactic function and chemokine receptor was evaluated.Results:There were no significant differences in general data between the two groups (all P > 0.05). At 1, 3 and 5 days after admission, the number of neutrophils, the number of white blood cells, and procalcitonin, C-reactive protein, interleukin-6, interleukin-10, and tumor necrosis factor-α levels in the burn group were significantly higher than those in the healthy control groups ( F = 12.56, 13.45, 15.78, 17.83, 22.56, 13.39, 10.82, all P < 0.05). At 1, 3 and 5 days after admission, neutrophil migration distance in the burn group was (1 510.22 ± 108.45) μm, (1 380.90 ± 115.67) μm, (1 026.10 ± 95.48) μm, respectively, which were significantly shorter than (1 944.67 ± 139.20) μM in the healthy control group ( t = 23.44, 25.67, 27.52, all P < 0.05). At 5 days after admission, chemokine receptors 1 and 2 positive rates in the burn group were (47.40 ± 1.76)% and (75.33 ± 2.42)%, respectively, which were significantly lower than (95.24 ± 4.89)% and (97.78 ± 2.10)% in the healthy control groups ( t = 4.92, 5.67, both P < 0.05). Correlation analysis showed that neutrophil migration distance was positively correlated with chemokine receptor expression in patients with deep second- and third-degree burns ( r = 0.72, 0.61, both P < 0.05). Conclusion:Neutrophil chemotactic function and chemokine receptor expression decrease in the early stage of deep second- and third-degree burns.
