AI Technical Summary
Technical Problem
The genetic transformation system of peanut plants is immature, which limits the genetic improvement at the molecular level. The quantity and function of conserved CLE peptides in peanuts are unclear, which affects the regulation of plant growth and development and genetic improvement.
Method used
Artificially synthesized peanut conserved CLE polypeptides H11, H12, and H14 were applied exogenously to Arachis plants, especially during the germination to flowering and pegging stages, by spraying to promote plant growth and development.
Benefits of technology
It increased the number of lateral roots, leaves, taproot length, and plant height, promoting plant growth and development and providing a theoretical basis for peanut genetic improvement and new germplasm creation.

Abstract
This invention belongs to the field of bioengineering technology, specifically relating to the application of conserved CLE peptides from peanuts in promoting plant growth and development. The conserved CLE peptides from peanuts are H11 peptides with amino acid sequences as shown in SEQ ID NO.1, H12 peptides with amino acid sequences as shown in SEQ ID NO.2, or H14 peptides with amino acid sequences as shown in SEQ ID NO.3. Experiments show that, compared with the control group without CLE peptide application, exogenous application of H11, H12, or H14 peptides can promote root and leaf development in peanuts. The plant polypeptide hormones provided by this invention can precisely regulate peanut root development and leaf growth, providing a novel biological agent for high-yield peanut cultivation.
