Low nitrogen use efficiency caused by irrational nitrogen
fertilization
restricts Tartary buckwheat (TB) yield improvement. CLE peptides are
key signaling molecules regulating plant nitrogen response, yet their
functions in TB remain unclear. Herein, 16 <i>FtCLE</i> genes
were identified in TB, and all encoding proteins contained conserved
bioactive CLE mature peptides. The root-specific and high nitrogen-induced
gene, <i>FtCLE7</i>, was screened as the key <i>CLE</i> member by expression analysis. Exogenous synthetic FtCLE7 peptide
treatment significantly promoted growth and nitrogen accumulation
in TB, and reshaped rhizosphere microbial communities. Transcriptome
analysis demonstrated that FtCLE7 peptide changed the expression of
genes involved in hormone signaling, phenylpropanoid biosynthesis,
transcription regulation, and receptor-like kinases. Additionally,
overexpression of <i>FtCLE7</i> in tobacco verified its
positive regulatory role in growth and nitrogen accumulation. This
study clarifies the biological function of <i>FtCLE7</i> in modulating nitrogen accumulation, providing a theoretical basis
for breeding nitrogen-efficient TB varieties and developing novel
peptide fertilizers.
