Background and Objectives Multigrain bread is bread prepared from multiple flours of different cereals. This review aims to assess the technological and nutritional properties of multigrain doughs and bread and discuss challenges and opportunities. Finding Increased consumer awareness of healthy nutrition urges the demand for beneficial health foods in the market. The primary aim of developing multigrain bread is to take care of the expanding demand for a healthy diet concerning the economy and exploit minor cereals. Multigrain bread includes grains such as wheat, rice, barley, oat, maize, rye, pseudocereals, and pulses and allows the development of products with enhanced nutritional profiles. Combining flours with differences in composition significantly affects the water absorption behavior and ultimately leads to a difference in dough handling and nutritional properties. Bread prepared from multigrain is nutritionally superior to 100% wheat‐based bread. Sometimes the development of multigrain products is a technological challenge as various grains are used, different in composition and nature, which affects the color, texture, and sensory attributes. Conclusion Consumer preference for multigrain bread increases due to its high nutritional profile and potential health benefits.

“…So far, the climate-crop studies mostly focused on crops i.e., rice, wheat, corn, and soybeans since these crops altogether contribute to 75% of the world's total calorie consumption [39,22]. This is at the exclusion of other minor crops like oats and sorghum, which could be a valuable alternative to combating food security under the current climate change scenario [40].…”

Recognizing the crop and region-specific irreversible effects of climate change on agriculture is unavoidable. The Southeastern United States region (SE-US) contributes significantly to the United States (US) economy through its diverse agricultural productivity. Climatically, this region is more vulnerable than the rest of the country. This study was designed to quantify the effect of changing climate, i.e., daily maximum temperature (Tmax), daily minimum temperature (Tmin), and precipitation, on oats (Avena sativa L.) and sorghum (Sorghum bicolor L. Moench) in SE-US. The panel data approach with a fixed effects model was applied by creating a production function on a panel dataset (1980–2020) of climate and yield variables. The required diagnostic tests were used to statistically confirm that the dataset was free of multi-collinearity, stationarity, and auto-correlation issues. The results revealed asymmetric warmings (Tmin increase > Tmax increase) over the region. Tmax and Tmin significantly increased during the oats growing season (OGS) and sorghum growing season (SGS). Precipitation increased during OGS and decreased during SGS. The annual average values of Tmax, Tmin, and Tavg (daily average temperature) have shifted by 1.08°C (0.027°C/year), 1.32°C (0.033°C/year), and 1.20°C (0.030°C/year) in OGS and by 0.92°C (0.023°C/year), 1.32°C (0.033°C/year), and 1.12°C (0.028°C/year) in SGS. However, precipitation had shifted by 23.2 mm (0.58 mm/year) in OGS and shifted (decreased) by -5.2 mm (-0.13 mm/year) in SGS. Precipitation had a non-significant effect on oats and sorghum yields. With every 1°C increase in Tmin and Tmax, oats yield was reduced by (-5%) and (-4%), respectively, whereas sorghum yield was increased by (+ 13%) and decreased by (-7%), respectively. Taken together, a 1°C net rise in overall temperature reduced oats yield (-9%) while increased sorghum yield (+ 6%).

“…Sorghum is the fifth most produced cereal crop worldwide and is an extremely tolerant plant against drought and temperature stresses. The crop is utilized for human and animal nutrition, as well as for forage, non-food products and the generation of bioenergy [ 1 ]. About 62 million tons of sorghum grain are estimated to be produced in 2022/2023 ( ; accessed on 8 August 2022).…”

The biotrophic fungus Sporisorium reilianum exists in two host-adapted formae speciales that cause head smut in maize (S. reilianum f. sp. zeae; SRZ) and sorghum (S. reilianum f. sp. reilianum; SRS). In sorghum, the spread of SRZ is limited to the leaves. To understand the plant responses to each forma specialis, we determined the transcriptome of sorghum leaves inoculated either with SRS or SRZ. Fungal inoculation led to gene expression rather than suppression in sorghum. SRZ induced a much greater number of genes than SRS. Each forma specialis induced a distinct set of plant genes. The SRZ-induced genes were involved in plant defense mainly at the plasma membrane and were associated with the Molecular Function Gene Ontology terms chitin binding, abscisic acid binding, protein phosphatase inhibitor activity, terpene synthase activity, chitinase activity, transmembrane transporter activity and signaling receptor activity. Specifically, we found an upregulation of the genes involved in phospholipid degradation and sphingolipid biosynthesis, suggesting that the lipid content of the plant plasma membrane may contribute to preventing the systemic spread of SRZ. In contrast, the colonization of sorghum with SRS increased the expression of the genes involved in the detoxification of cellular oxidants and in the unfolded protein response at the endoplasmic reticulum, as well as of the genes modifying the cuticle wax and lipid composition through the generation of alkanes and phytosterols. These results identified plant compartments that may have a function in resistance against SRZ (plasma membrane) and susceptibility towards SRS (endoplasmic reticulum) that need more attention in the future.
