EST analysis of mRNAs expressed during embryogenesis in Gallus gallus.
Chicken Expressed Sequence Tags (ESTs) were analyzed to identify genes associated with myogenesis during embryonic development. A total of 6,184 ESTs were generated from three cDNA libraries constructed from whole embryos (Stage 26), somites associated with neural tube (Stage 15), and limb buds (Stages 21, 24 and 26). Clustering and assembly of 4,998 valid ESTs resulted in 2,329 unique sequence...
متن کامل[3H]Uridine incorporation during previtellogenesis and early vitellogenesis in the oocytes of the chick (Gallus gallus).
During the weeks following hatching of poultry, oocyte differentiation is most advanced in the central part of the ovarian cortex. For instance, in the 5-day-old chicken, oocytes surrounded by a ring of cuboidal cells (constituting early follicles) are appearing in the central part of the cortex. At the extreme periphery of the same cortex one occasionally can find a few germ cells which are st...
متن کاملGenetic characterization of Bhutanese native chickens based on an analysis of Red Junglefowl (Gallus gallus gallus and Gallus gallus spadecieus), domestic Southeast Asian and commercial chicken lines (Gallus gallus domesticus)
The genetic diversity of Bhutanese chickens needs to be understood in order to develop a suitable conservation strategy for these birds in Bhutan. In this, work, we used microsatellite markers to examine the genetic diversity of Bhutanese chickens. Four Bhutanese chicken varieties (Black plumage, Frizzle, Naked neck and Red Junglefowl-like, corresponding to Yuebjha Narp, Phulom, Khuilay and Sei...
متن کاملMultimodal signaling in fowl, Gallus gallus.
Many social birds produce food-associated calls. In galliforms, these vocalizations are typically accompanied by a distinctive visual display, creating a multimodal signal known as tidbitting. This system is ideal for experimental analysis of the way in which signal components interact to determine overall efficacy. We used high-definition video playback to explore perception of male tidbitting...
متن کاملIn vitro synapse formation among peripheral neurons of the domestic chicken embryo, Gallus gallus
INTRODUCTION: The nervous system is composed of neurons and glial cells, the system functions via communication of these cells (Kandel, Schwatz, Jessell, Siegelbaum, & Hudspeth, 2013). Cellular communication in the nervous system is termed synaptic transmission and occurs at synapses. Neurons develop synapses as their axons choose post-synaptic partners and their axon terminals differentiate in...
