Models that include supercoiling of topological domains reproduce several known features of interphase chromosomes
Understanding the structure of interphase chromosomes is essential to elucidate regulatory mechanisms of gene expression. During recent years, high-throughput DNA sequencing expanded the power of chromosome conformation capture (3C) methods that provide information about reciprocal spatial proximity of chromosomal loci. Since 2012, it is known that entire chromatin in interphase chromosomes is ...
متن کاملLunge feeding in early marine reptiles and fast evolution of marine tetrapod feeding guilds
Traditional wisdom holds that biotic recovery from the end-Permian extinction was slow and gradual, and was not complete until the Middle Triassic. Here, we report that the evolution of marine predator feeding guilds, and their trophic structure, proceeded faster. Marine reptile lineages with unique feeding adaptations emerged during the Early Triassic (about 248 million years ago), including t...
متن کاملPrior host feeding experience influences ovipositional but not feeding preference in a polyphagous insect herbivore
Black vine weevils, Otiorhynchus sulcatus (Fabricius) (Coleoptera: Curculionidae), are globally-distributed polyphagous pests of many horticultural crops. We investigated how adult weevils were affected by host switching and, in particular, how host plant species nutritional and defensive chemistry affected subsequent host plant species selection and oviposition. Adults were fed one of three ho...
متن کاملPhytoecdysteroids: Isolation and Biological Applications
Phytoecdysteroids are analogues of arthropod steroid hormones found in plants, where they deter predation by non-adapted predators. Their discovery in several plant species displayed a wide array of rather beneficial agricultural impact. An overview is given on both well-known and recently discovered phytoecdyteroids including a sophisticated isolation scheme and notable physiological and pharm...
متن کاملAttractiveness of Native Mammal’s Feces of Different Trophic Guilds to Dung Beetles (Coleoptera: Scarabaeinae)
Mammal feces are the primary food and nesting resource for the majority of dung beetle species, and larval development depends on the quantity and quality of that resource. Physiological necessities, competitive interactions, and resource sharing are common and suggest that dung beetles may show preferences for feces of greater nutritional quality, which may in turn impact beetle assemblages an...
