Pectinase and cellulase participate in cell wall degradation during secretory cavity formation in Citrus fruits. However, it remains unknown how secretory cavity formation is regulated by pectinase and cellulase genes in a schizolysigenous model. Our Results showed that PCD was involved in the schizolysigenous formation of the secretory cavities, and pectinase was involved in the degradation of the middle lamella while pectinase combined with cellulase were responsible for the degradation of the primary cell wall. Furthermore, the expression levels of CisPG21 and CisCEL16 at the intercellular space-forming and lumen-expanding stages with the continuous degradation of the cell wall were significantly higher than those at the initial cell stage and mature stage. The in situ hybridization (ISH) results also showed that CisPG21 and CisCEL16 were mainly located in the degrading cells of secretory cavities, and signals were very strong at the intercellular space-forming and lumen-expanding stages. In conclusion, pectinase and cellulase are directly involved in the degradation of PCD cell walls during schizolysigenous formation in the secretary cavity of Citrus sinensis (L.) Osbeck fruit, while CisPG21 and CisCEL16 are important regulatory genes of pectinase and cellulose during cell wall degradation.
