Meanwhile, J. chinensis presents three sexes: female (FP), male (MP) and monoecious (MOP), with leaf morphological differentiation into scale leaves (SL) and spiny leaves (SPL). Variations in sexes and leaf morphogenesis may affect the establishment of tissue culture systems. However, there are currently no studies that have established tissue culture systems by integrating both sex and leaf morphogenesis, and the differences in responses of explants with different sexes and leaf morphogenesis during culture remain unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Using SL and SPL from FP, MP and MOP as explants, we optimized explant disinfection protocols, screening of culture medium, selection of anti-browning agents, determination of antioxidant enzyme activities, proliferation and rooting culture, plant hardening and transplantation. We comprehensively explore the differences in the process of establishing tissue culture among J. chinensis with different sexes and leaf morphogenesis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Results<\/jats:title>\n                    <jats:p>Disinfection of explants with two types of leaf morphogenesis from three sexes can be achieved by treating them with sodium hypochlorite (NaClO) for 18\u2005min. The basal medium suitable for the early growth of explants of the three sexes and two leaf morphogenesis types is Douglas-fir Cotyledon Revised medium (DCR). Polyvinylpyrrolidone (PVP) can inhibit browning by reducing the activity of oxidases. During the proliferation stage, explants derived from MOP demonstrate consistent hormone requirements. The efficiency of adventitious bud proliferation of SPL is notably higher than that of SL, and all proliferated adventitious buds are SPL. At the rooting stage, the rooting ability of adventitious buds from SPL is inferior to that of SL. Conversely, MOP still maintain consistent hormone demands during the rooting stage. After transplantation, sterile plants display vigorous growth, with stem segments undergoing progressive lignification, and the survival rate shows variability influenced by both sexes and leaf morphogenesis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study established a multi-dimensional tissue culture system for J. chinensis based on three sexes (FP, MP and MOP) and their corresponding SL and SPL. It analysed the differences and preferences among different sexes and leaf forms at various stages of tissue culture, providing technical support for the targeted breeding, germplasm resource innovation and industrial development of J. chinensis. Meanwhile, it offers novel perspectives for research on sex differentiation, mechanisms of leaf form transformation and other related areas in polygamous or heterophyllous tree species.<\/jats:p>\n
