Fleshy fruits represent a very important economic resource and, therefore, they are an ideal target for biotechnological ameliorations. However, because of their physiological and anatomical characteristics, ripe fleshy fruits represent an extremely difficult material for transient gene expression assays aimed at the study of gene promoters in a short time.(More)
Strawberry fruits (Fragaria x ananassa Duch.) undergo a marked softening during their ripening, and the process is accompanied by a release of free sugars with galactose among them. In this work total beta-galactosidase activity was measured in cell wall proteins from strawberry fruits at different developmental stages. Three full-length cDNAs (Fa beta(More)
Two full-length cDNA clones (faEG1 and faEG3, respectively) have been isolated by screening a cDNA library representing transcripts from red strawberry fruits. Southern blot analysis of genomic DNA suggests that the strawberry endo-β-1,4-glucanases (EGases) are encoded by a multigene family. The cognate genes are predominantly expressed during the ripening(More)
Two endo-beta-1,4-glucanase (EGase; EC genes, highly expressed during ripening of the non-climacteric strawberries (Fragariaxananassa Duch. cv. Chandler), were isolated. Serial promoter deletions of both genes (i.e. FaEG1 and FaEG3) fused to GUS were transiently assayed in strawberry fruits by using a technique recently developed in this(More)
Three cDNA clones (pCel10, pCel20 and pCel30), each encoding different endo-β-1,4-glucanases in peach, were obtained by RT-PCR and their expression investigated by northern analysis during leaf and fruit abscission and during fruit development. This analysis allowed the detection of only the pCel10-related mRNA. A 2.2 kb transcript accumulated in ethylene(More)
