Introduction: Symptoms of gastric motility disorders are common clinical manifestations of functional gastrointestinal disorders (FGIDs), and are triggered and exacerbated by stress, but the neural pathways underpinning them remain unclear.

Methods: We set-up a mouse model by gastric dilation (GD) in which the gastric dynamics were assessed by installing strain gauges on the surface of the stomach. The neural pathway associated with gastric motility disorders was investigated by behavioral tests, electrophysiology, neural circuit tracing, and optogenetics and chemogenetics involving projections of the corticotropin-releasing hormone (CRH) from the paraventricular nucleus of the hypothalamus (PVN) to acetylcholine (ChAT) neurons in the dorsal motor nucleus of the vagus (DMV).

The cDNA sequences of 26 starch synthesis genes were identified in common wheat (Triticum aestivum L.), and their transcript levels were measured using quantitative real-time RT-PCR to assess the function of individual genes and the regulatory mechanism in wheat endosperm. The expression patterns of 26 genes in wheat endosperm were classified into three groups.
