Non-trellised culture of tomato is gaining interest among farmers cultivating long shelf-life (LSL) landraces because the reduction in production costs. This cropping system can benefit from selection determinate growth genotypes, mirroring advancements achieved processing tomatoes. With this aim, and profiting natural variation found within Penjar landrace, we selected traditional genotypes br...

A recently promoted genome evolution model posits that mammalian pseudogenes can regulate their founding source genes, and it thereby ascribes an important function to "junk DNA." This model arose from analysis of a serendipitous mouse mutant in which a transgene insertion/deletion caused severe polycystic kidney disease and osteogenesis imperfecta with approximately 80% perinatal lethality, wh...

epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...

Environmental sex determination (ESD) is present in several animal and plant lineages. Diverse factors such as temperature, light or water availability have been described as sex determinants in these organisms. Among plants, ferns frequently display ESD. This work compares the effect of different levels of water availability in two diploid species of the xerophytic fern genus Cheilanthes and i...

In this study we examine a moderated model of group faultlines, team identification, and group performance outcomes. We extend research on faultlines by showing how different faultline bases (social category and information-based faultlines) may have differential effects on the performance of groups. In addition to faultline strength (the extent of demographic alignment across members within a ...

Studies in a wide variety of organisms have produced a general model for the induction of apoptosis in which multiple signaling pathways lead ultimately to activation of the caspase family of proteases. Once activated, these enzymes cleave key cellular substrates to promote the orderly dismantling of dying cells. A broad similarity exists in the cell death pathways operating in different organi...
