Breeding between Saccharomyces species is a useful tool for obtaining improved wine yeast strains, combining fermentative features of parental species. In this work, 25 artificial Saccharomyces cerevisiae x Saccharomyces uvarum hybrids were constructed by spore conjugation. A multi-locus PCR-restriction fragment length polymorphism (PCR-RFLP) analysis, targeting six nuclear gene markers and the...

Heterosis, the phenotypic superiority of a hybrid over its parents, has been demonstrated for many traits in Arabidopsis thaliana, but its effect on defence remains largely unexplored. Here, we show that hybrids between some A. thaliana accessions show increased resistance to the biotrophic bacterial pathogen Pseudomonas syringae pv. tomato (Pst) DC3000. Comparisons of transcriptomes between th...

Through distant crossing, diploid, triploid and tetraploid hybrids of red crucian carp (Carassius auratus red var., RCC♀, Cyprininae, 2n = 100) × topmouth culter (Erythroculter ilishaeformis Bleeker, TC♂, Cultrinae, 2n = 48) were successfully produced. Diploid hybrids possessed 74 chromosomes with one set from RCC and one set from TC; triploid hybrids harbored 124 chromosomes with two sets from...

in this study 18 corn hybrids consist of 15 new early and mid mature foreign hybrids and three commercial iranian corn hybrids (ksc704, ksc647 and dc370) as controls were evaluated at two rcbd with three replications at the khorasan razavi agricultural research and natural resources center, during 2008 -2010. results showed that hybrid exp1 and dc370 with 16.5 and 12.1 t.ha-1 were the best and ...

The purpose of these studies was to examine the antiproliferative properties of 16 recombinant human IFN-alpha B/D hybrids against various human tumor lines of different histological origin and to determine whether any of the hybrid molecules possessed immunomodulating activity that could active antitumor properties in peripheral blood monocytes of normal donors. Hybrids with the B domain at th...
