Claim 1: a method for regulating the growth of non root parts of plants, which is characterized by (a) linking the leaves, buds or stems of plants or any combination thereof with the root structure regulatory peptide (CEP),Or (b) antagonizing the leaves, buds or stems of these plants or any combination thereof with a marker for a strain； or (c) introducing at least one alien variation or nucleic acid into one or more plant cells, (d) Introduce at least one exogenous nucleic acid or variability into one or more plant cells in one or more plant cells, or in a factory containing one or more such plant cells；To regulate in this way the expression of a strain receptor in regenerated plant cells or in cells of plants containing one or more such plant cells； or (E) to introduce at least one foreign variation or nucleic acid into one or more plant cells, Therefore, the affinity of one or more provisional election committees is regulated by their respective recipients, among which the affinity expressed by one or more provisional election committees, one or more provisional election committee recipients or one or more provisional election committee and one or more provisional election committee recipients may change. Claim 7: method of dealing with any claims 1 to 6,characterized in that the CEP comprises an amino acid sequence that is selected from SEQ ID No. 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36 to 147, 338 to 350, 365, 367, 369, 371, 373, 375, 377, 379, 381, 383, 385, 387 to 395, 468, 470, 472, 474, 476, 478, 480, 482, 484, 486 488, 491, 493, 499 or 501, comprises a domain of a CEP that has an amino acid sequence that is selected from SEQ ID NOS: 148 to 336, 351 to 363, 396 to 415, 451 to 453, 455 to 466 or 502 to 504 or is encoded by a nucleic acid comprising a nucleotide sequence which is selected from SEQ ID No. 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 , 27, 29, 31, 33, 35, 337,Ibid., paragraphs 364, 366, 368, 370, 372, 374, 376, 378,
