Background  Developing tolerant cultivars by incorporating resistant genes is regarded as a potential strategy for controlling Verticillium wilt that causes severe losses in the yield and fiber quality of cotton.    Results  Here, we identified the gene  GbHyPRP1  in  Gossypium barbadense , which encodes a protein containing both proline-rich repetitive and Pollen Ole e I domains. GbHyPRP1 is located in the cell wall. The transcription of this gene mainly occurs in cotton roots and stems, and is drastically down-regulated upon infection with  Verticillium dahliae . Silencing  HyPRP1  dramatically enhanced cotton resistance to  V. dahliae . Over-expression of  HyPRP1  significantly compromised the resistance of transgenic  Arabidopsis  plants to  V. dahliae . The  GbHyPRP1  promoter region contained several putative phytohormone-responsive elements, of which SA was associated with gene down-regulation. We compared the mRNA expression patterns of  HyPRP1 -silenced plants and the control at the global level by RNA-Seq. A total of 1735 unique genes exhibited significant differential expression. Of these, 79 DEGs involved in cell wall biogenesis and 43 DEGs associated with the production of ROS were identified. Further, we observed a dramatic thickening of interfascicular fibers and vessel walls and an increase in lignin in the  HyPRP1 -silenced cotton plants compared with the control after inoculation with  V. dahliae . Additionally, silencing of  HyPRP1  markedly enhanced ROS accumulation in the root tips of cotton inoculated with  V. dahliae .    Conclusions  Taken together, our results suggest that  HyPRP1  performs a role in the negative regulation of cotton resistance to  V. dahliae  via the thickening of cell walls and ROS accumulation.
