Abstract:Small secreted peptides (SSPs) are essential for defense
mechanisms
in plant–microbe interactions, acting as danger-associated
molecular patterns (DAMPs). Despite the first discovery of SSPs over
three decades ago, only a limited number of SSP families, particularly
within Solanaceae plants, have been identified due to inefficient
approaches. This study employed comparative genomics screens with
Solanaceae proteomes (tomato, tobacco, and pepper) to discover a novel
SSP family, SolP. Bioinformatics analysis sug… Show more
