Rock2 and Rock3, two new variants of function gain of cytokinin receptors AHK2 and AHK3

摘要

An isolated nucleic acid, comprising a nucleic acid sequence encoding a constitutively active variant of the cytokinin AHK2 receptor with: i) an amino acid sequence with SEQ ID No.1 or an ortholog thereof; ii) an amino acid sequence that it has at least 48%, preferably at least 50%, more preferably at least 55% identity over the entire sequence length of SEQ ID No.1; oiii) an amino acid sequence having at least 50%, preferably at least 53%, more preferably 55% identity on a 50 amino acid sequence segment of SEQ ID No. 1 having SEQ ID No. 5; where The amino acid sequence has the amino acid phenylalanine (F) in a position corresponding to position 552 of SEQ ID No.1.
