The genetic basis for panicle trait variation in switchgrass (Panicum virgatum)
L. Zhang et al. "The genetic basis for panicle trait variation in switchgrass (Panicum virgatum)" Theoretical and Applied Genetics 135 (2022) [DOI:10.1007/s00122-022-04096-x]
We investigate the genetic basis of panicle architecture in switchgrass in two mapping populations across a latitudinal gradient, and find many stable, repeatable genetic effects and limited genetic interactions with the environment.

Comparative transcriptomics and metabolomics reveal specialized metabolite drought stress responses in switchgrass (Panicum virgatum)
K. Tiedge et al. "Comparative transcriptomics and metabolomics reveal specialized metabolite drought stress responses in switchgrass (Panicum virgatum)" New Phytologist 236 (2022) [DOI:10.1111/nph.18443]
To investigate specialized metabolic drought responses in switchgrass, we integrated tissue-specific transcriptome and metabolite analyses of the genotypes Alamo and Cave-in-Rock that feature different drought tolerance. The more drought-susceptible Cave-in-Rock featured an earlier onset of transcriptomic changes and significantly more differentially expressed genes in response to drought compared to Alamo.

Metagenomes and metagenome-assembled genomes from microbiomes metabolizing thin stillage from an ethanol biorefinery
N.W. Fortney et al. "Metagenomes and metagenome-assembled genomes from microbiomes metabolizing thin stillage from an ethanol biorefinery" Microbiology Resource Announcements 11 (2022) [DOI:10.1128/mra.00290-22]

Functional divergence in a multi-gene family is a key evolutionary innovation for anaerobic growth in Saccharomyces cerevisiae
D. Krause and C. Hittinger "Functional divergence in a multi-gene family is a key evolutionary innovation for anaerobic growth in Saccharomyces cerevisiae" Molecular Biology and Revolution 39 (2022) [DOI:10.1093/molbev/msac202]
When the model budding yeast Saccharomyces cerevisiae transitions to anaerobic growth conditions, the cell massively induces the expression of seven serine/threonine-rich anaerobically-induced cell wall mannoproteins (anCWMPs): TIP1, TIR1, TIR2, TIR3, TIR4, DAN1, and DAN4. Here, we show that these genes likely derive evolutionarily from a single ancestral anCWMP locus, which was duplicated and translocated to new genomic contexts several times both prior to and following the budding yeast whole genome duplication (WGD) event.

To identify shared and divergent mechanisms of toxicity and to implicate gene targets for genetic engineering, we used a chemical genomic approach to study fitness effects across a library of S. cerevisiae deletion mutants cultured anaerobically in dozens of individual compounds found in different types of hydrolysates.

Host genotype controls ecological change in the leaf fungal microbiome
A. VanWallendael et al. "Host genotype controls ecological change in the leaf fungal microbiome" PLOS Biology (2022) [DOI:10.1371/journal.pbio.3001681]

Leaf fungal microbiomes can be fundamental drivers of host plant success, as they contain pathogens that devastate crop plants and taxa that enhance nutrient uptake, discourage herbivory, and antagonize pathogens. We measured leaf fungal diversity with amplicon sequencing across an entire growing season in a diversity panel of switchgrass (Panicum virgatum).

The transcriptomes of Zymomonas mobilis 2032 were captured during the fermentation of ammonia fiber expansion (AFEX)-pretreated corn stover and switchgrass hydrolysates containing different concentrations of glucose and xylose. RNA samples were collected when Z. mobilis was fermenting glucose or xylose.

Comparative functional genomics identifies an iron-limited bottleneck in a Saccharomyces cerevisiae strain with a cytosolic-localized isobutanol pathway
F. V. Gambacorta et al. "Comparative functional genomics identifies an iron-limited bottleneck in a Saccharomyces cerevisiae strain with a cytosolic-localized isobutanol pathway" Synthetic and Systems Biotechnology 7 (2022) [DOI: 10.1016/j.synbio.2022.02.007]
Metabolic engineering strategies have been successfully implemented to improve the production of isobutanol, a next-generation biofuel, in Saccharomyces cerevisiae. Here, we explore how two of these strategies, pathway re-localization and redox cofactor-balancing, affect the performance and physiology of isobutanol producing strains.

Microbial communities using anammox bacteria to remove nitrogen are increasingly important in wastewater treatment. We report on 25 metagenome-assembled genomes of low-abundance microbes from a partial nitritation anammox bioreactor system that have not been described previously.

Intraspecific variability in root traits and edaphic conditions influence soil microbiomes across 12 switchgrass cultivars
T. C. Ulbrich et al. “Intraspecific variability in root traits and edaphic conditions influence soil microbiomes across 12 switchgrass cultivars” Phytobiomes 5 (2021) [DOI: 10.1094/PBIOMES-12-19-0069-FI]
We used a common garden experiment to investigate variation in 12 mature switchgrass cultivar soil microbiomes and, furthermore, to examine how root traits and soil conditions influence microbiome structure. We found that average root diameter varied up to 33% among cultivars and that the cultivars also associated with distinct soil microbiomes.
