dc.description.abstract | To gain a better understanding of the molecular mechanisms controlling microspore embryogenesis (ME) in triticale (×Triticosecale Wittm.), the expression patterns of 13 genes, previously identified in bread wheat to be associated with microspore-derived embryo development, were analysed. Four triticale doubled haploid (DH) lines, significantly different with respect to embryogenic potential, were studied. The gene expression profile was dissected at different points of the ME induction procedure up to the 8th day of in vitro culture (dc). RT-PCR revealed that these 13 genes were expressed during triticale ME. Variations in gene expression profiles were observed between the studied DH lines. DH28 (highly embryogenic) was the only one in which all analysed genes (Ta.TPD1-like, TAA1b, GSTF2, GSTA2, CHI3, Tad1, XIP-R1, TaAGL14, TaNF-YA7, SERK2, SERK1, TaEXPB4, TaME1) were up-regulated during the first 8dc. In the less embryogenic DH31, TAA1b, GSTA2 and TaEXPB4 were already induced on 4dc. In DH25, ME was initiated quite efficiently but soon inhibited, which coincided with the lack of gene expression (TaEXPB4, TaME1) or down-regulation (Tad1, XIP-R1, TaAGL14, TaNF-YA, SERK2, SERK1) on 8dc. In the recalcitrant DH50 line, the majority of genes were expressed at a lower level or not at all, indicating disturbances in ME initiation. In this study, the molecular mechanisms involved in triticale ME induction were analysed for the first time, laying the foundation for further characterisation of specific genes controlling microspore-derived embryo development. | es_ES |
