Abstract:

We investigated the expression pattern of four major starch genes at different seed developmental stages in the radiation-bred amaranth variety “Pribina” (Amaranthus cruentus L.) and corresponding control genotype “Ficha” (Amaranthus cruentus L.). Two platforms were used and compared for the gene expression analysis of GBSSI, SSSI, SBE, and DBE amaranth genes, including a standard quantitative real-time PCR (qPCR) technique and relatively novel droplet digital PCR (ddPCR) assay. In our conditions, both methods showed great accuracy and revealed higher expression of the investigated genes in the mutant variety than in the control genotype. Here we report for the first time, a ddPCR gene expression assay for the cultivated grain amaranth, as the most important group of the species in the genus Amaranthus.

Abstract:

The Amaranth plants are annuals or short-lived perennials with over 103 species of flowering plants in the family Amaranthaceae, distributed nearly worldwide. Several amaranth species are useful as food crops and are grown both for their leaves and for their edible seeds, which are a nutritious pseudocereal (nongrass seeds used like cereal grains). This paper reports the genetic diversity of three species of Amaranthus (A. hybridus L., A. viridis L. and A. spinosus L.) in Rivers state of Nigeria. Result obtained from this research showed high rate of diversity. DNA characterization and sequencing of the species were done through plastid Ribulose-1,5biophosphate Carboxylase large chain (rbcL) genetic marker to determine the rate of genetic variation among members of this genus in our study area. The sequence figures were firstly compared on Basic Local Alignment Sequence Tool for validation. Phylogenetic and molecular evolutional analysis was conducted using MEGA version 7. The dendogram of the molecular phylogeny generated from MEGA 7 software shows elevated rate of variation among studied species.Keywords: Amaranthus, Genetic, Diversity, rbcl

Abstract:

Common waterhemp (Amaranthus rudis) and pigweeds (Amaranthus spp.) are troublesome weeds in many cropping systems and have evolved resistance to several herbicides. Field trials to further develop Microsphaeropsis amaranthi and Phomopsis amaranthicola as bioherbicides for control of waterhemp and pigweeds were conducted to test the effectiveness of these organisms in irrigated and nonirrigated pumpkin and soybean plots over 2 years at three locations in western Illinois. The bioherbicide was applied with lecithin and vegetable oil at 187 liters ha–1 in 2008 and 374 liters ha–1 in 2009. Treatments included spore suspensions of M. amaranthi and P. amaranthicola alone, a mixture of both organisms, and sequential treatments of the organisms with halosulfuron-methyl (Sandea Herbicide) in pumpkin or glyphosate (Roundup Original Max Herbicide) in soybean. Bioherbicide effectiveness was estimated at approximately 7 and 14 days after treatment, as disease incidence, disease severity, percent weed control, and weed biomass reduction. Significant reductions in weed biomass occurred in treatments with one or both of the fungal organisms, and potential exists to tank mix M. amaranthi with halosulfuron-methyl. Leaf surface moisture and air temperatures following application may account for inconsistencies in field results between year and locations. These fungal organisms show potential as bioherbicides for weeds in the genus Amaranthus.

Abstract:

A taxonomic revision of the genus Amaranthus (Amaranthaceae) in Italy is here presented. Field surveys were carried out during the period 2006–2014. 58 herbaria (both European and American, including 12 personal herbaria) were consulted (more than 3,000 specimens were examined) as well as extensive literature was analized. Twenty-seven non-hybrid taxa (twenty-four species, and six varieties) are recognized (A. crassipes and A. graecizans subsp. graecizans are considered doubtful for the flora of Italy). Three taxa (A. blitum, A. cacciatoi, and A. graecizans subsp. sylvestris) are native, one (A. bouchonii) has doubtful origin, while the others are to be considered aliens, mostly neophytes native to the Americas. Information about nomenclature (accepted names, main synonyms, and types), morphology, chromosome number, chorology (for native taxa) or alien status (for exotic taxa, at national and regional levels), occurrence in Italy (at regional scale), ecology (preferential habitat, phenology, elevation), taxonomic annotations are provided for each taxon, as well as original photos were prepared. Diagnostic keys at species and infraspecific levels (for A. blitum subsp. blitum s.l., A. emarginatus s.l., and A. graecizans s.l.) are given. An isolectotype for the name A. bouchonii was found at Z. A list of the seven hybrids recorded and their main morphological characteristics are also given. Among them, A. × mauritii is recorded in the present study for the first time in Italy. The nomenclatural change Amaranthus × pyxidatus comb. et stat. nov. is proposed. Two specimens preserved at MPU are designated as lectotype and isolectotype of the name A. × mauritii s.s., while for A. × mauritii f. ramosissima the holotype was found; the two names are to be considered heterotypic synonyms (new synonymy).

Abstract:

A nomenclatural study of Amaranthus names, linked to the dioecious taxa belonging to the sect. Saueranthus (subgen. Acnida), was carried out. All studied names are validly published but in need of nomenclatural clarifications. Lectotypes are designated for A. greggii var. muelleri (NY), whereas for A. ambigens, A. annectens, A. arenicola, A. myrianthus, and A. watsonii holotypes were cited (deposited at US, BM, GH, and US). Isotypes where found for A. ambigens (one specimen at NY), A. myrianthus (five specimens at GH, M, MO, RM, and US), and A. arenicola (three specimens at KSC, MO, and US), whereas for A. watsonii two isotypes were traced at US. A new synonymy, A. arenicola = A. myrianthus, is proposed, the latter name having nomenclatural priority to the former one. Based on preliminary taxonomic observations, two varieties are recognized under A. greggii, var. greggii and var. muelleri, which differ from each other on the ratio tepals/fruit (about 2/3 in var. muelleri vs. about 1 in var. greggii).

Abstract:

The present study concentrated on the development of an analytical method for determination of emissions of volatile organic compounds from crude and heat treated amaranth (genus <i>Amaranthus</i> L.) samples. Emitted substances were collected by solid-phase microextraction (SPME) method and identified by gas chromatography with mass spectrometry. The list of identified abundant organic compounds exceeds one hundred substances of different classes. Total concentrations of quantified volatile organic compounds ranged between 2.2 and 68.9 μg/g of dried sample. Hexanal and acetic acid were found as the most abundant compounds detected in amaranth samples. It was found that heat treatment (popping) of amaranth samples changed their composition of volatile organic compounds dramatically. The highest volatile organic compound emissions were found in popped grain amaranth in comparison to all crude grains and amaranth biomasses.

Abstract:

As part of the ongoing studies of the genus Amaranthus Linnaeus (1753: 990) and in the course of the preparation of a new checklist of the vascular plants alien to the flora of Italy (see e.g., Iamonico 2015, 2016; Galasso et al. 2016, 2018), following the checklist of vascular plants native to Italy (Bartolucci et al. 2018), we present here a note regarding some names applied to hybrids of Amaranthus.

Abstract:

The genus Amaranthus contains many species which are common weeds found on the Texas high plains. In a field experiment plant height and numbers of plants of Amaranthus varied when grown with different Allium genotypes: Allium fistulosum var. `Heshiko' and an interspecific F1 hybrid 81215 (Heshiko × A. cepa cv. `New Mexico Yellow Grano'). The genotypes that showed no allelopathic effect were A. cepa cv `New Mexico Yellow Grano', A. fistulosum var. `Ishikura', and their F1 hybrid 8273. On the basis of these observations experiments have been done to quantify the degree of suppression. A randomized complete block design was used under greenhouse conditions in order to measure growth characters of Amaranthus.

Abstract:

The thesis deals with the content of selected phenolic compounds in some species of the genus Amaranthus, in black elderberry (Sambucus nigra L.) and buckwheat (Fagopyrum esculentum M.). Phenolic compounds are a group of natural compounds exclusively vegetable character. Flavonoids represent only one group of phenolic compounds. Flavonoids show many positive biological effects, in particular act as antioxidants. Natural flavonoids may cause to prevent from coronary- heard diseases and other diseases associated with older age. In recent years the increased attention is paid to flavonoid investigation due to its biological effects. For the determination of phenolic substances there were used two independent analytical methods. There are the high-performance liquid chromatography (HPLC) and micellar electrokinetic capillary chromatography (MECC). The MECC method was used for determination rutin and free quercetin. The highest content of rutin was found in leaves of buckwheat (76,400 mg/kg of dry weight) and the lowest content of rutin was determined in buckwheat hulls. The highest content of rutin was observed in teas from buckwheat leaves and inflorescence. This amount of rutin corresponds with rutin content in more than two pills of Ascorutin (the most favourite flavonoid medicament in the Czech Republic) The HPLC method was used for quantitative determination of phenolic acids. The content of free quercetin was monitored in all samples. No free quercetin was found both in plant material and in samples of teas. The ethanolic extract from the elderberry inflorescence didn´t contain any free quercetin. Free quercetin wasn?t found in any further samples of teas, which were prepared by described methods.
