Summary Thlapsi arvense L. (pennycress) is being developed as a profitable oilseed cover crop for the winter fallow period throughout temperate regions of world, controlling soil erosion and nutrients run‐off on otherwise barren farmland. We demonstrate that pennycress can serve user‐friendly model system akin to Arabidopsis well‐suited both laboratory field experimentation. sequenced diploid genome spring‐type Spring 32‐10 inbred line (1C DNA content 539 Mb; 2 n = 14), identifying variation...
The Lamiaceae family, which includes basil, sage, and thyme, has long been recognized as a rich source of diverse unique anthocyanins. development intensely purple pigmented basil in the ornamental herb trade prompted this examination eight commercial varieties basils (Ocimum basilicum L.) potential new Anthocyanins were isolated characterized utilizing high-performance liquid chromatography, spectral data, plasma desorption mass spectrometry. Fourteen different anthocyanins isolated,...
ABSTRACT Field pennycress ( Thlaspi arvense L.; hereafter pennycress) is an oilseed crop being investigated as off‐season biofuel source that can potentially fit into the existing rotation cycle with soybean [ Glycine max (L.) Merr.]. The objective of this 2‐yr study was to evaluate effect residue on seed yield and quality components planted during five consecutive weeks, from mid‐May mid‐June. In 2009 2010, mean dry weight after for all planting dates (4108 3490 kg ha −1 , respectively)...
Pennycress (Thlaspi arvense) is under development to be grown as a winter annual intermediate oil seed bioenergy crop in the Midwest during typical fallow periods. Crucial work remains domesticate and optimize pennycress for incorporation into cropping systems increasing resilience rising temperatures. We found that increased planting density reduces biomass swiftens time flowering maturity, which are features associated with shade avoidance responses. In controlled conditions, we elongates...
Considerable offseason farmland lays fallow because there are few crops that can profitably fit between primary crops. To remedy, we employed CRISPR genome editing to the freeze-tolerant, rapid cycling wild Brassica, Thlaspi arvense L. (field pennycress). High-yielding domesticated pennycress varieties were created having seed compositions comparable double low canola (low erucic acid and glucosinolate). Seed glucosinolate content was reduced 75 % by combining mutations in R2R3-MYB (MYB28)...
Pennycress ( Thlaspi arvense ) is a promising intermediate oilseed crop, producing oil suitable for conversion to biofuels—including aviation fuels. While domestication efforts are ongoing, deeper understanding of the genetic architecture traits crucial informing future breeding efforts. Here, we conducted largest genomic and phenotypic survey pennycress date, analyzing 739 accessions collected across four continents. Leveraging whole-genome sequencing field-collected phenotypes,...
The instability of the purple pigments (anthocyanins) in basil varieties (Ocimum basilicum L.) limits their use as ornamental plants and a potential anthocyanin source. Several self-pollinated generations all were unsuccessful stabilizing expression. In this study we investigated inheritance stability patterns leaf traits using Purple Ruffles variety. results from complete diallele crosses indicated expression vegetative tissue is controlled by two dominant genes ruffled texture single...
Abstract Diversification of agroecological systems to enhance agrobiodiversity is likely be critical advancing environmental, economic, and social sustainability agriculture. Temperate-zone that are currently organized for production summer-annual crops can diversified by integration fallow-season perennial crops. Integration such improve these systems, with minimal interference current agricultural production. Importantly, provide feedstocks a wide range new bio-products forming bioeconomy,...
Abstract Oilseed pennycress ( Thlaspi arvense L.) establishment following grain corn Zea mays harvest in northern latitudes is challenging because of the short duration between and soil freeze. The use shorter season hybrids for a region may partly solve this challenge, but tradeoffs reduced yield be concern. This study evaluated relative maturity (CRM) on establishment, seed oil yields, tradeoffs. CRM ranged from 76‐ to 95‐day sites (Morris Rosemount, MN), 95‐ 113‐day southern (Custar, OH,...
Flies are frequent visitors to flowers of many species plants within the mustard family (Brassicaceae). They derive nutrition from these flowers, and some fly pollinators. Field pennycress (Thlaspi arvense) is a that being developed as new "cash cover crop," i.e., an autumn-sown crop whose oil-rich seeds can be harvested profitably in spring. Although largely wind- self-pollinated, its also attract insect visitors. However, extent visitation by flies remains unknown, especially identities...
Thlaspi arvense L. (pennycress) is a cold-tolerant Brassicaceae that produces large amounts of seeds rich in triacylglycerols and protein, making it an attractive target for domestication into offseason oilseed cash cover crop. Pennycress easily genetically transformed, enabling synthetic biology approaches to tailor oil properties specific biofuel industrial applications. To test the feasibility pennycress producing TAGs acetyl-TAGs medium-chain fatty acids (MCFAs; C6–C14) industrial,...
Abstract Oilseed pennycress ( Thalspi arvense L.) is a crop that has undergone domestication for use as new oilseed option in parts of the United States biofuel and livestock feed production but does not yet have management resources such growth staging guide. Winter types this may utility existing summer annual rotations throughout much U.S. Midwest by growing during fall/winter fallow period. This guide contains an adaptation Biologische Bundesanstalt, Bundessortenamt und Chemische...
Abstract Field pennycress ( Thlaspi arvense ) is a new biofuel winter annual crop with extreme cold hardiness and short life cycle, enabling off-season integration into corn soybean rotations across the Midwest. Pennycress fields are susceptible to snow melt spring rainfall, leading waterlogged soils. The objective of this research was determine if waterlogging during reproductive stage had significant effect on gene expression, morphology, physiology, recovery, yield two lines (SP32-10...
Partial seed retention line #23(‘PSR23’) cuphea is a hybrid of Cuphea viscosissima × C. lanceolata. It new, spring-planted, annual, potential oilseed crop that highly susceptible to interference by weeds because its slow growth during spring and early summer. Grass are controlled easily in this broadleaf crop, but an appreciable problem. Consequently, several herbicides were screened for tolerance ‘PSR23’ cuphea. Broadleaf which showed spray cabinet greenhouse tested field setting 2 yr....
Abstract Pennycress ( Thlaspi arvense L.) is an emerging bioenergy oilseed crop of interest to farmers in the Upper Midwestern United States. Improved lines with beneficial agronomic traits are being developed, including reduced silicle shattering and altered seed coat characteristics, though planting establishment still challenging for this small‐seeded crop. A controlled‐environment experiment was conducted assess impact treatment pelleting on pennycress germination seedling vigor four...
