Project description:Transcriptional profiling of populations in the clam Ruditapes decussatus determined differentiation in gene-expression along parallel temperature gradients and between races of the Atlantic Ocean and West Mediterranean sea.
Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. A microarray-based analysis was performed with the objectives of describe genomic feature of oocytes and identify potential markers of oocyte quality in the economically important European clam, Ruditapes decussatus. The oocytes of a total of 25 females from Ria de Aveiro, Western coast of Portugal, were selected for this study and their quality was estimated by early developmental success until D-larval rate, under controlled conditions.
Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. Microarray analyses have been performed in four gonadal maturation stages of two higly productive Portuguese wild populations (Ria Formosa in South and Ria de Aveiro in North) characterized by different responses to spawning induction.
