Molecular Analysis of the Gibberellin Signaling Pathway Genes in Cultivated Rye (Secale cereale L.)

Gibberellin signaling pathway genes encoding the DELLA protein and gibberellin receptor GID1 were sequenced in several varieties (Alpha, Valdai, Orlovskaya 9, Pracha) and one line of rye (EM-1) using next generation methods. The revealed multiple alleles of these genes differ mainly in single-nucleotide polymorphisms and less frequently in insertions and deletions. Most of the detected mutations turned out to be synonymous or located in the noncoding regions of the genes. Changes in the amino acid sequences of proteins associated with other mutations are probably functionally neutral. Mutations similar to wheat reduced-height gibberellin-insensitive alleles were not detected.
