New types of precooked pasta products have been developed based on refined and wholegrain wheat and spelt flours. The resulting dry pasta was then assessed for chemical composition, including amino acids composition, phenolics content, as well as antioxidant activity. The precooked pasta quality was also evaluated for starch gelatinization degree, physical properties, hardness, color profile of dry and hydrated pasta, and sensory characteristics. We found that the application of the extrusion-cooking technique for wheat and spelt pasta processing allows to achieve instant products with good nutritional characteristics and high degree of gelatinization, as well as attractive quality and sensory profiles. Microstructure showed compact and dense internal structure with visible bran particles if wholegrain flours were used. Wholegrain wheat and wholegrain spelt precooked pasta were characterized by better nutritional composition and greater antioxidant potential, but lower firmness and increased adhesiveness when compared with refined flours.

Background: Sucrose non-fermenting-1-related protein kinases (SnRKs) have been implicated in plant growth and stress responses. Although SnRK3.23 is known to be involved in drought stress, the underlying mechanism of resistance differs between Arabidopsis and rice, and little is known about its function in wheat.

Advancements in bioinformatic tools and breakthroughs in high throughput RNA sequencing have unveiled the potential role of non-coding RNAs in influencing the overall expression of disease-responsive genes. Owing to the increasing need to develop resilient crop varieties against environmental constraints, our study explores the functional relationship of various non-coding RNAs in wheat during leaf rust pathogenesis. MicroRNAs (miRNAs) and circular RNAs (circRNAs) were retrieved from SAGE and RNA-Seq libraries, respectively, in the susceptible (HD2329) and resistant (HD2329 + Lr28) wheat Near-Isogenic Lines (NILs).

This study focused on identifying amylase-trypsin inhibitors (ATIs) in seven Norwegian-cultivated wheat varieties, including common wheat and ancestral species, and identifying potentially harmful opioid peptides within the digesta of these wheats. LC-MS/MS analysis of tryptic peptides from ATI fractions revealed that the common wheat variety Børsum exhibited the highest diversity of ATIs ( = 24), while they were less represented in tetraploid emmer ( = 11). Hexaploid wheat Bastian showed low diversity and relative abundance of ATIs.

This study aimed to explore the mechanism by which Zn retards Fe toxicity by analyzing the morphological, photosynthetic, and chloroplast physiological parameters of wheat seedlings treated with either single or combined Zn and Fe. Different behavior of the seedlings was observed under untreated and treated conditions. The most discriminating quantitative traits were associated with leaf area, biomass dry mass and fresh mass, net photosynthetic rate, intercellular CO concentration, stomatal conductance, transpiration rate of seedlings, Hill reaction, Mg-ATPase and Ca-ATPase activities, malondialdehyde and O contents, and glutathione reductase, ascorbate peroxidase, peroxidase, and superoxide dismutase activities and their gene expression in the seedling chloroplast.
