Floral induction in Brachypodium distachyon
Brachypodium distachyon (L.) P. Beauv. is a recently fully-sequenced monocot plant, very closely related to wheat and barley, and an attractive model system to study the biology of temperate cereals. The present work investigates the “mechanisms” of flowering time in Brachypodium (community …

Investigating Root Storage and Exudation in the Brachypodium Genus
… our plants. We use multiple species from the Brachypodium genus, an annual, B. distachyon, and a perennial, B. sylvaticum for this study. We chose this genus because it has evolved annuality and perenniality multiple times, and it is a good model for several economically valuable species. Most …

Regulation of Gene Expression by Non-coding RNAs in Arabidopsis and Brachypodium
… in two plant model systems, Arabidopsis and Brachypodium. We set out to investigate whether the Arabidopsis exosome complex modulates gene expression through regulating ncRNAs, including both smRNAs and lncRNAs. Thus, the role of Arabidopsis exosome complex in regulating smRNA metabolism was …

Pseudomonas/Brachypodium as a Model System for Studying Rhizosphere Plant Microbe Interactions Under Water Stress
… synxantha</em> 2-79 and annual grass <em>Brachypodium distachyon</em> Bd21. 2-79 exemplifies a group of rhizobacteria associated with dryland wheat, while <em>B.</em> <em>distachyon </em>originates from the Middle East and has emerged as a model for valuable biomass, food, forage, and turf …

Investigating the Capacity of Generative AI to Learn Genotype-by-Environment Interactions in Brachypodium distachyon
… bulk RNA-seq data from two natural accessions of Brachypodium distachyon grown under drought and control conditions. The model was trained on binned expression values using both a baseline configuration and a set of regularized variants incorporating noise injection, co-expression preservation, …

The effects of invasive slender false-brome (Brachypodium sylvaticum) on forest ecosystem function in western New York
… further invasion. Slender false-brome (Brachypodium sylvaticum) is an exotic bunchgrass that is invasive in North America. Its encroachment into forest understories may have implications for ecosystem processes and characteristics. The goal of this study was to understand the impacts of …

Brachypodium distachyon as a genetic model pathosystem to study resistance against fungal pathogens of small grain cereals
… reduced ET-sensitivity, or developmental delay. Brachypodium distachyon (Bd) has the potential to serve as a model pathosystem relevant to small-grain cereals. Chapter 3 provides evidence of compatibility between Bd and the main causal agents of FHB and shows that symptom development mirrors …

Systems Analysis of Plant Responses to Drought
… study two genotypes of the model grass species Brachypodium distachyon, leveraging natural variation and RNA-sequencing to study their responses to drought stress. (2) Natural perturbations can be used to understand complex traits. In wild species, limited resources drive allocation strategies …

The agronomic and molecular characterisation of Rht8 in hexaploid wheat
… of 1.34 Mb on rice chromosome 4, 1.36 Mb on Brachypodium chromosome 5, 2.9 Mb on barley 2H and 4.25 Mb on Ae. tauschii 2D. Disruption to micro-collinearity was found with Brachypodium and rice, with better but imperfect collinearity with Ae. tauschii and barley. Rht8 was also anchored to a …

Elucidating the Molecular Pathways Involved in the Fitness and Water Stress Response of Pseudomonas synxantha 2-79 in the Plant Rhizosphere
… less competitive in the colonization of the <em>Brachypodium</em> rhizosphere than its wild-type parental strain. The analysis of <em>alg, psl</em>, and <em>eps</em> biofilm matrix pathways revealed their role in the protection of 2-79 from desiccation. These pathways also contributed redundantly …

Dissecting Earliness per se and Photoperiod heading date effects in bread wheat (Triticum aestivum)
… genes on 1DL, 1BL and 5AL QTL regions using the Brachypodium distachyon syntenic genes. Resequencing genes on 1DL revealed that Spark and Cadenza have a chromosomal deletion including several genes. The equivalent region in Rialto and Avalon is intact. The DH, SSD and NILs all showed that the 1DL …

Soil drying and re-wetting effects on phosphorus availability and plant yields
… -38 MPa) and re-wetting soil prior to planting Brachypodium distachyon in pots significantly increased available P at transplanting (by 1 mg kg-1) and doubled grain yields independent of P fertiliser application. In a field trial in central Madagascar in low-P, highly P-fixing soil, applying …

Transgenic approaches to improve photosynthesis and nitrogen use in wheat
… expressions specialised to wheat leaves, two Brachypodium promoters, SBPase and FBPA, were cloned upstream of the GUS fusion gene and transformed into wheat leaves. Consequently, both promoters resulted in detectable GUS expression in wheat leaves at different growth stages and did not show …
