Compensatory Effect of the ScGrf3-2R Gene in Semi-Dwarf Spring Triticale (x Triticosecale Wittmack).

ABSTRACT: The dwarfness in many triticale cultivars is provided by the dominant Ddw1 (Dominant dwarf 1) allele found in rye. However, along with conferring semi-dwarf phenotype to improve resistance to lodging, this gene also reduces grain size and weight and delays heading and flowering. Grf (Growth-regulating factors) genes are plant-specific transcription factors that regulate plant growth, including stem growth, in terms of length and thickness, and leaf and fruit size. In this work, we partially sequenced the rye gene ScGrf3 on chromosome 2R homologous to the wheat Grf3 gene, and found multiple polymorphisms in intron 3 and exon 4 complying with two alternative alleles (haplotypes ScGrf3-2Ra and ScGrf3-2Rb). For the identification of these
