Abstract

The actin-depolymerizing factor (ADF) gene family regulates changes in actin. However, the entire ADF family in the sweet orange Citrus sinensis has not been systematically identified, and their expressions in different organs and biotic stress have not been determined. In this study, through phylogenetic analysis of the sweet orange ADF gene family, seven CsADFs were found to be highly conserved and sparsely distributed across the four chromosomes. Analysis of the cis-regulatory elements in the promoter region showed that the CsADF gene had the potential to impact the development of sweet oranges under biotic or abiotic stress. Quantitative fluorescence analysis was then performed. Seven CsADFs were differentially expressed against the invasion of Xcc and CLas pathogens. It is worth noting that the expression of CsADF4 was significantly up-regulated at 4 days post-infection. Subcellular localization results showed that CsADF4 was localized in both the nucleus and the cytoplasm. Overexpression of CsADF4 enhanced the sensitivity of sweet orange leaves to Xcc. These results suggest that CsADFs may regulate the interaction of C. sinensis and bacterial pathogens, providing a way to further explore the function and mechanisms of ADF in the sweet orange.

Abstract

BACKGROUND Anterior talofibular ligament (ATFL) is the most easily injured or even broken of ankle sprain. Patients who fail to receive conservative treatment, resulting in persistent ankle swelling, painful and functional decline that it is so-called chronic lateral ankle instability (CLAI). It makes sense to investigate all-inside arthroscopic reconstruction of ATFL with InternalBrace™ for CLAI. MATERIAL AND METHODS We included 108 patients who underwent all-inside arthroscopic ATFL reconstruction with InternalBrace™ for CLAI from January 2018 to April 2020 through a retrospective study. Patients age ranged from 19 to 58 years (mean 35.6±8.7 years). Several elements are used to evaluate the clinical consequences of ankle function, including the American Orthopedic Foot and Ankle Society (AOFAS), Japanese Society for Surgery of the Foot Ankle-Hindfoot (JSSF), Kofoed, Tegner scores and complications, and the tilt angle of talus (TT) and the anterior displacement of talus (ADT) with stressing radiographs were taken to measure in follow-ups. RESULTS All 108 patients had all-inside arthroscopic procedures performed smoothly without serious complications. During the follow-up period (26.7±2.6 months on average), no recurrence of ankle instability and other serious complications happened. The AOFAS, JSSF, Kofoed, and Tegner scores significantly increased as time went by postoperatively, which proved statistically significant (P0.01). Regarding stress-radiographic measurements, TT significantly decreased from (9.5±1.1)° preoperatively to (2.6±0.6)° at the latest follow-up (P0.01), while ADT significantly decreased from (9.5±1.0) mm preoperatively to (2.6±0.6) mm at the latest examination (P0.01). CONCLUSIONS All-inside arthroscopic ATFL reconstruction with the InternalBrace™ for CLAI is beneficial for ankle stability, allowing earlier return to activities.
