Abstract Barley (Hordeum vulgare L.) is one of the most important global crops. The six-row barley cultivar Morex reference genome has been used by the barley research community worldwide. However, this reference genome can have limitations when used for genomic and genetic diversity analysis studies, gene discovery, and marker development when working in two-row germplasm that is more common to Canadian barley. Here we assembled, for the first time, the genome sequence of a Canadian two-row malting barley, cultivar AAC Synergy. We applied deep Illumina paired-end reads, long mate-pair reads, PacBio sequences, 10X chromium linked read libraries, and chromosome conformation capture sequencing (Hi-C) to generate a contiguous assembly. The genome assembled from super-scaffolds had a size of 4.85 Gb, N50 of 2.32 Mb and an estimated 93.9% of complete genes from a plant database (BUSCO, benchmarking universal single-copy orthologous genes). After removal of small scaffolds (< 300 Kb), the assembly was arranged into pseudomolecules of 4.14 Gb in size with seven chromosomes plus unanchored scaffolds. The completeness and annotation of the assembly were assessed by comparing it with the updated version of six-row Morex and recently released two-row Golden Promise genome assemblies.

AbstractCell-free gene expression (CFE) systems from crude cellular extracts have attracted much attention for biomanufacturing and synthetic biology. However, activating membrane-dependent functionality of cell-derived vesicles in bacterial CFE systems has been limited. Here, we address this limitation by characterizing native membrane vesicles in Escherichia coli-based CFE extracts and describing methods to enrich vesicles with heterologous, membrane-bound machinery. As a model, we focus on bacterial glycoengineering. We first use multiple, orthogonal techniques to characterize vesicles and show how extract processing methods can be used to increase concentrations of membrane vesicles in CFE systems. Then, we show that extracts enriched in vesicle number also display enhanced concentrations of heterologous membrane protein cargo. Finally, we apply our methods to enrich membrane-bound oligosaccharyltransferases and lipid-linked oligosaccharides for improving cell-free N-linked and O-linked glycoprotein synthesis. We anticipate that these methods will facilitate on-demand glycoprotein production and enable new CFE systems with membrane-associated activities.

Abstract Barley grain containing more fermentable starch or fiber might be an attractive energy source in weaned pig diets due to benefits on gut health. Barley rapidly-fermentable carbohydrates may serve as prebiotic and slowly-fermentable fiber may decrease diarrhea in weaned pigs. Steam-explosion processing may disrupt the fiber matrix of hulls, increasing slowly-fermentable fiber of barley. To explore, 220 pigs were fed 1 of 5 diets containing 60% cereal grain: 1) low-fermentable hulled barley (LFB); 2) LFB steam-exploded (LFB-E; 1.2 MPa, 120 s); 3) high β-glucan (10% DM) hull-less barley (HFB); 4) high amylose (17% DM) hull-less barley (HFA); or 5) low-fermentable wheat (LFW). Diets were fed starting 1-week post-weaning and formulated to provide 2.4 and 2.3 Mcal net energy (NE)/kg, 5.5 and 5.1 g standardized ileal digestible lysine/Mcal NE for phase 1 (day 1–14) and phase 2 (day 15–35), respectively. For the entire trial (day 1–35), average daily feed intake (ADFI) and average daily gain (ADG) of pigs did not differ among diets. Gain:feed (G:F) did not differ between LFB and LFW diets, but steam-explosion of hulled barley reduced (P < 0.05) G:F. Feces consistency did not differ between LFB and LFW diets, but was better (P < 0.05) for LFB than HFB, HFA and LFB-E diets. For phase 1, G:F of pigs was lower (P < 0.05) for LFB-E diet than LFW diet. For days 22–28, LFB-E diet had greater (P < 0.01) ADFI than HFA diet and tended (P = 0.09) to have a greater ADG than HFB diet. In conclusion, hulled or hull-less barley grain replaced wheat grain without affecting growth performance in weaned pigs. Hulled barley increased feces consistency. Steam-explosion of hulled barley did not increase growth performance of weaned pigs. Barley grain is an attractive energy source for weaned pigs for managing growth and feces consistency.
