Angiosperm fertilization has been a hot topic in the field of sexual plant reproduction. In recent years, great advances have been made in the studies on some critical steps, such as pollen tube guidance, polytubey block, and fertilization recovery system. However, most of these known mechanisms are synergid cell-based for ensuring successful double fertilization, the counterpart system based on central cell remains poorly understood. A recently published paper from Hongju Li’s lab revealed that the central cell could also secrete peptides as pollen tube attractants to guide the pollen tube entering embryo sac to ensure double fertilization. Interestingly, this mechanism is not synergid-dependent. Thus, the authors revealed a novel fertilization recovery system and bridged a gap in understanding the mechanism underlying double fertilization.
