Resumo: Seeds of Magnolia ovata were dried to different water contents to assess the viability and transcript abundance of genes related to seed development, cell cycle, cytoskeleton and desiccation tolerance.The expression of development, cell cycle and cytoskeleton relative genes (ABI3, CDC2-like and ACT2) alone could not explain the germination behaviour of M. ovata seeds in relation to drying damage. Irrespective of their initial water content, the seeds performed in the same way during the initial period of germination and the deleterious effects of desiccation only occurred in later stages. Expression of PKABA1, sHSP17.5 and 2-Cys-PRX did not show a relationship with desiccation. However, the expression patterns of PKABA1 and sHSP17.5 suggested the participation of these genes in protective mechanisms during the imbibition of M. ovata seeds.

A expressão de transcritos dos genes relacionados ao desenvolvimento, ciclo celular e citoesqueleto (ABI3, CDC2-like e ACT2) não explicou o comportamento germinativo de sementes de M. ovata em relação aos danos ocasionados pela secagem. Aparentemente as sementes comportam-se da mesma maneira nos primeiros dias de embebição, independentemente do conteúdo de água inicial. A expressão dos transcritos dos genes PKABA1, sHSP17.5 e 2-Cys-PRX não mostraram relação com a dessecação, entretanto, o padrão de expressão de PKABA1 e sHSP17.5 sugere a participação destes genes em mecanismos de proteção durante a embebição de sementes de Magnolia ovata.Associação Brasileira de Tecnologia de Sementes2016-12-21T12:39:49Z2016-12-21T12:39:49Z2008info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfJOSÉ, A.
