Cereal biomacromolecules are an important source not just of calories but also of functional ingredients in foods and as raw materials for biodegradable nonfood applications. Their important role is evidenced by an ever‐increasing number of peer‐reviewed publications on these topics. Current research is increasingly focused on understanding the fine structure of the macromolecules and their interactions with other ingredients within a food matrix for their impact on health. Furthermore, these learnings about the fine structure and interactions have relevance to functionality in nonfood applications. This focus issue attempts to summarize the state of the knowledge and research gaps related to the three major biomacromolecules in cereals: starch, proteins, and nonstarch polysaccharides (dietary fiber).

A method for forecasting banana flowering distribution in the Jordan Valley, using the previous year's meteorological and flowering data, is described. The forecasting is done at the beginning of May of each year, for the subsequent flowering season.Reliable prediction of flowering distribution is of great importance for planning agrotechnical operations, work scheduling and establishing marketing policy. 相似文献

Elevated carbon dioxide concentrations and limited water supply have been shown to reduce the impact of ozone pollution on the growth and physiology of Quercus petraea in a long-term factorial experiment. These responses can be explained by observed reductions in stomatal conductance, and thus potential ozone exposure of 28% and 40% for CO2 and drought treatments respectively. However, parameterisation of a stomatal conductance model for Quercus robur and Fagus sylvatica grown under ambient and elevated CO2 concentrations in a separate experiment has demonstrated that elevated CO2 also reduces the responsiveness of stomata to both saturation deficit (LAVPD) and soil moisture deficit (ψ) in beech, and to a lesser extent, in oak. Season-long model simulations of ozone fluxes suggest that LAVPD and ψ conductance parameters derived at ambient CO2 concentrations will lead to these fluxes being underestimated by 24% and 2% for beech and oak respectively at 615 ppm CO2. 相似文献
