Characterization of pigments from cultivated Amaranthus species and assessment of their commercial applications as natural food colorants
… and high cost of red beets. Vegetable amaranth (Amaranthus spp.) is a particularly appealing alternative to beets because of its high concentrations of betacyanin pigments and status as a ubiquitous low-maintenance crop that is resilient to many of the environmental stresses that afflict …

Herbicide resistant weeds in Missouri : sources and solutions
… were examined for the presence of weed seed. Amaranthus species were present in 94 of the 98 bags of bird feed examined and reached levels as high as 6,525 seeds kg[-1].. Results from linear regression and t test analysis indicate that when proso millet, grain sorghum, and corn were present in …

Development and Characterization of Microsatellite Markers for the Grain Amaranths (Amaranthus spp. L.)
The grain amaranths (Amaranthus hypochondriacus L., A. cruentus L., and A. caudatus L.) are important pseudocereals native to the Americas that have received increased attention for their nutritional content, specifically their balance of amino acids. The objective of this project was to produce …

Hybridization Between Amaranthus Tuberculatus and Amaranthus Hybridus
… alleles may be transferred among related species. Studies have shown that weedy Amaranthus species are capable of interspecific hybridization, and hybridization may foster the evolution of herbicide resistance. Yet, much remains unknown as to the dynamics of Amaranthus interspecies gene …

The Significance of Inter- and Intraspecific DNA Content Variation in Agriculturally Important Species
… variation in agriculturally important plant species and determined any differences. The nuclear DNA content of 40 Malus species and hybrids was examined using flow cytometry. Estimates of total nuclear DNA content for this collection ranged from 1.45 pg for a diploid variety to 2.57 pg for a …

Understanding gender determination in dioecious Amaranthus weeds palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus)
… of weed management. As of today, 217 weed species have been reported to have established resistance to the herbicides. Furthermore, resistance was reported to all major known herbicide modes of action. This rapid rise in herbicide resistance among key weed species requires immediate …

A comparative study of the population dynamics of four Amaranthaceae species
… are found in the Amaranthaceae family, such as Amaranthus palmeri and A. tuberculatus. These summer annual weeds are troublesome due to their competitive ability, high seed production, and resistance to herbicides from several modes of action which complicates management in field crops and has …

Discovery, surveillance, and management of herbicide-resistant amaranthus spp
Amaranthus species are considered key driver weed species within Midwestern agricultural production systems. Herbicides are often relied upon for the control of Amaranthus spp. In recent years, herbicide resistance at multiple sites of action, such as 5-enolpyruvylshikimate-3-phosphate synthase …
