Thus, the present study used 3-day canola seed sprouting followed by hull removal to improve the nutritional quality of canola as a feed and food ingredient to further enhance and diversify the canola market.

Results: Seed sprouting and the hull removal process resulted in 63.

Fusarium head blight resistance exacerbates nutritional loss of wheat grain at elevated CO.

The nutritional integrity of wheat is jeopardized by rapidly rising atmospheric carbon dioxide (CO) and the associated emergence and enhanced virulence of plant pathogens. To evaluate how disease resistance traits may impact wheat climate resilience, 15 wheat cultivars with varying levels of resistance to Fusarium Head Blight (FHB) were grown at ambient and elevated CO. Although all wheat cultivars had increased yield when grown at elevated CO, the nutritional contents of FHB moderately resistant (MR) cultivars were impacted more than susceptible cultivars At elevated CO, the MR cultivars had more significant differences in plant growth, grain protein, starch, fructan, and macro and micro-nutrient content compared with susceptible wheat.

Phenolic sucrose esters: evolution, regulation, biosynthesis, and biological functions.

Phenolic sucrose esters (PSEs) are a diverse group of specialized metabolites that are present in several angiosperm lineages. Phylogenetic reconstruction and structural variation suggest that these metabolites may have evolved independently in monocots and dicots. Constitutive variation in PSE abundance across plant organs and developmental stages is correlated with transcriptional regulation of the upstream phenylpropanoid pathway, whereas pathogen induction is regulated by stress-related phytohormones such as ethylene.

Changes in Wheat Nutritional Content at Elevated [CO] Alter Growth and Mycotoxin Production on Grain.

Rising atmospheric [CO] has been shown to impact plant primary metabolism and the severity of head blight (FHB) in wheat. In this study, we evaluated how changes in grain nutritional content due to growth at elevated [CO] affected growth and mycotoxin production. Susceptible (Norm) and moderately resistant (Alsen) hard spring wheat grains that had been grown at ambient (400 ppm) or elevated [CO] (800 ppm) were independently inoculated with two fungal strains, which produce the trichothecene mycotoxin, deoxynivalenol.

Biopesticide synergy when combining plant flavonoids and entomopathogenic baculovirus.

Four crop plants known to be hosts for the lepidopteran Trichoplusia ni (soybean, green bean, cotton, and cabbage) were treated with the biopesticide AfMNPV baculovirus in a dosage response assay. Treated soybean had, on average, a 6-fold increase in virus activity compared with the other crops. Leaf trichomes on soybeans were not found to be responsible for the observed increase of insecticidal activity.

Quantitative NIR determination of isoflavone and saponin content of ground soybeans.

Over 3200 discrete soybean samples were obtained from production locations around the United States during the years 2012-2016. Ground samples were scanned on near infrared spectrometers (NIRS) and analyzed by HPLC for total isoflavone and total saponin composition, as well as total carbohydrate composition. Multiple Linear Regression (MLR) analysis of preprocessed spectral data was used to develop optimized models to predict isoflavone content.

We conducted bioassays to determine the toxicity of Italian honeysuckle (Lonicera caprifolium) essential oil and its fractions against larvae of the yellow fever mosquito, Aedes aegypti.

Results: Sixteen constituents were identified in honeysuckle essential oil compared to 15, 15, 15, and 11 constituents in fractions A, B, C, and E, respectively.

Unique Flavanol-Anthocyanin Condensed Forms in Apache Red Purple Corn.

Anthocyanin pigments from purple corn are being explored as a potential alternative to artificial colorants and for their health-promoting properties. However, all pericarp-pigmented corn varieties examined to date primarily contain cyanidin-derived anthocyanins, which produce bluish-red or pink extracts. Here we describe the first pelargonidin-dominant pericarp-pigmented corn lines from the landrace Apache Red (AR).

Dormancy-defense syndromes and tradeoffs between physical and chemical defenses in seeds of pioneer species.

Seeds of tropical pioneer trees have chemical and physical characteristics that determine their capacity to persist in the soil seed bank. These traits allow seeds to survive in the soil despite diverse predators and pathogens, and to germinate and recruit even decades after dispersal. Defenses in seedlings and adult plants often are described in terms of tradeoffs between chemical and physical defense, but the interplay of defensive strategies has been evaluated only rarely for seeds.

Utilization of Quercetin as an Oviposition Stimulant by Lab-Cultured in the Presence of Conspecifics and a Tissue Substrate.

Background: The discovery of natural products to improve the reproductive performance of mass-reared predators is an important aim for successful augmentative biological control. We tested the hypothesis that quercetin (a bioflavonoid) stimulates oviposition by the ladybird beetle in the presence of conspecifics and a tissue substrate.

Methods: We conducted bioassays in solitary cages (housing one female) and communal cages (housing 10 females) to estimate daily oviposition site preferences, egg production in response to quercetin in the presence or absence of a tissue paper substrate, and female “resting” positions.

Do Bioflavonoids in Heartwood Stimulate Oviposition in the Ladybird ?

Maximizing the reproductive potential of ladybird beetles fed factitious foods or artificial diets, in lieu of natural prey, is a major challenge to cost-effective mass rearing for augmentative biological control. In this study, we tested the hypothesis that compounds in redcedar, , stimulate oviposition in the ladybird . We also tested the prediction that several bioflavonoids, identified in heartwood fractions, elicited this behavioral response.

Interspecific variation in persistence of buried weed seeds follows trade-offs among physiological, chemical, and physical seed defenses.

Soil seedbanks drive infestations of annual weeds, yet weed management focuses largely on seedling mortality. As weed seedbanks increasingly become reservoirs of herbicide resistance, species-specific seedbank management approaches will be essential to weed control. However, the development of seedbank management strategies can only develop from an understanding of how seed traits affect persistence.

Identification, Recombinant Expression, and Biochemical Analysis of Putative Secondary Product Glucosyltransferases from Citrus paradisi.

Flavonoid and limonoid glycosides influence taste properties as well as marketability of Citrus fruit and products, particularly grapefruit. In this work, nine grapefruit putative natural product glucosyltransferases (PGTs) were resolved by either using degenerate primers against the semiconserved PSPG box motif, SMART-RACE RT-PCR, and primer walking to full-length coding regions; screening a directionally cloned young grapefruit leaf EST library; designing primers against sequences from other Citrus species; or identifying PGTs from Citrus contigs in the harvEST database. The PGT proteins associated with the identified full-length coding regions were recombinantly expressed in Escherichia coli and/or Pichia pastoris and then tested for activity with a suite of substrates including flavonoid, simple phenolic, coumarin, and/or limonoid compounds.
