Key message The transcriptomes of wild and cultivated grapes consists of similar expressed genes but distinct wiring of co-expressed modules associated with environmental conditions. Abstract Grapevine is an important fruit crop worldwide, with high economic value and widespread distribution. Commercial production is based on Vitis vinifera, and, to a lesser extent, on hybrids with American grapes, such as V. labrusca. Wild grape relatives are important sources of resistance against biotic and abiotic factors; however, their global gene expression patterns remain poorly characterized. We associated genome-wide transcript profling to phenotypic analyses to investigate the responses of cultivated and wild vines to vineyard conditions. The expressed genes in the Vitis reference transcriptome are largely shared by wild grapes, V. labrusca hybrids and vinifera cultivars. In contrast, signifcant diferential regulation between wild and vinifera genotypes represents 80% of gene expression variation, regardless of the environment. In wild grapes, genes associated to regulatory processes are downregulated, whereas those involved in metabolic pathways are upregulated, in comparison to vinifera. Photosynthesis-related ontologies are overrepresented in the induced genes, in agreement with higher contents of chlorophyll in wild grapes. Co-regulated gene network analyses provide evidence of more complex transcriptome organization in vinifera. In wild grapes, genes involved in signaling pathways of stress-related hormones are overrepresented in modules associated with the environment. Consensus network analyses revealed high preservation within co-regulated gene modules between cultivated and wild grapes, but divergent relationships among the expression clusters. In conclusion, the distinct phenotypes of wild and cultivated grapes are underlain by diferences in gene expression, but also by distinct higher-order organization of the transcriptome and contrasting association of co-expressed gene clusters with the environment.

Conteúdo: |
Um experimento envolvendo 168 capotes de um dia de idade, de ambos os sexos, foi conduzido com o objetivo de verificar o efeito de diferentes niveis de energia e proteina no desempenho dos capotes durante a fase inicial (1 a 28 dias de idade). O delineamento experimental de blocos ao acaso consistiu em um arranjo fatorial 3x4, tres niveis de energia (2.800, 3.000 e 3.200 kcalEM/kg) e quatro niveis de proteina (20, 22, 24 e 26%) com quatorze aves por tratamento sendo cada ave uma repeticao as condicoes de temperatura variaram de 25 a 31 C e 78% de umidade relativa durante o periodo experimental. Os resultados mostram que niveis mais altos de energia (3.000 e 3.200 kcal EM/kg) e proteinas (24 e 26% das racoes causaram aumento (P<0,05) no ganho de peso e melhor (P<0,05) conversao alimentar. O consumo de racao nao foi afetado significativamente (P>0,05) pelos tratamentos. Tambem nao houve efeito significativo da interacao energia x proteina em nenhuma das variaveis estudadas. |
