Abstract Phytosulfokine-α (PSK-α), a sulfated pentapeptide with the sequence
YIYTQ, is encoded by a small precursor gene family in Arabidopsis. PSK-α regulates multiple growth and developmental processes as a novel peptide hormone.
Despite its importance, functions of PSK-α in M. truncatula growth remains
unknown. In this study, we identified five genes to encode PSK-α precursors in
M. truncatula. All of these precursors possess conserved PSK-α signature motif.
Expression pattern analysis of these MtPSK genes revealed that each gene was
expressed in a tissue-specific or ubiquitous pattern and three of them were remarkably expressed in root. Treatment of M. truncatula seedlings More >
