Small peptides play key roles for plant reproduction, especially in the male-female communication. In this issue, Huang et al. (pp. 518–521) show that cysteine-rich peptides represent a major class of genes expressed in the female gametophyte during ovule maturation, fertilization and early seed development in Arabidopsis. The cover shows pollens from proLAT52::GFP proHTR10:HTR10-RFP transgenic plants moving towards ovules in vitro. Red fluorescence in ovules is from auto-fluorescence.
