Grain amaranth Amaranthus hypochondriacus L. However, the features of Al-induced secretion of organic acid anions OA and potential genes responsible for OA secretion are poorly understood.

Single-molecule sequencing and Hi-C-based proximity-guided assembly of amaranth Amaranthus hypochondriacus chromosomes provide insights into genome evolution. Background: Amaranth Amaranthus hypochondriacus was a food staple among the ancient civilizations of Central and South America that has recently received increased attention due to the high nutritional value of the seeds, with the potential to help alleviate malnutrition and food security concerns, particularly in arid and semiarid regions of the developing world.

Here, we present a reference-quality assembly of the amaranth genome which will assist the agronomic development of the species. Full Text Available Extraction of squalene, a potent natural antioxidant, from puffed A. Chemical proximal composition and seed morphology were determined in raw, puffed, and SCFE-extracted seeds.

The squalene content was determined and the fatty acids present in the extracts were identified by GC-MS. French ,.

Amaranto , bredo. Amaranthus tricolor L. English , Amarante Here, Al-induced OA secretion in grain amaranth roots was characterized by ion charomatography and enzymology methods, and suppression subtractive hybridization SSH together with quantitative real-time PCR qRT-PCR was used to identify up-regulated genes that are potentially involved in OA secretion. The results showed that grain amaranth roots secrete both oxalate and citrate in response to Al stress.

The secretion pattern, however, differs between oxalate and citrate. Neither lanthanum chloride La nor cadmium chloride Cd induced OA secretion. A total of 84 genes were identified as up-regulated by Al, in which six genes were considered as being potentially involved in OA secretion.

The expression of a gene encoding tonoplast dicarboxylate transporter and four genes encoding ATP-binding cassette transporters was differentially regulated by Al stress, but the expression pattern was not correlated well with that of oxalate secretion.

Our results not only reveal the secretion pattern of oxalate and citrate from grain amaranth roots under Al stress, but also provide some genetic information that will be useful for further characterization of genes involved in Al toxicity and tolerance mechanisms.

The novel and taxonomically restricted Ah24 gene from grain amaranth Amaranthus hypochondriacus has a dual role in development and defense.

Full Text Available Grain amaranths tolerate stress and produce highly nutritious seeds. We have identified several abiotic stress-responsive genes of unknown function in Amaranthus hypochondriacus , including the so-called Ah24 gene. Ah24 was expressed in young or developing tissues; it was also strongly induced by mechanical damage, insect herbivory and methyl jasmonate and in meristems and newly emerging leaves of severely defoliated plants.

Interestingly, an in silico analysis of its bp promoter region showed a predominance of regulatory boxes involved in development, but not in defense. The Ah24 cDNA encodes a predicted cytosolic protein of amino acids, the localization of which was confirmed by confocal microscopy.

Additional in silico analysis identified several other Ah24 homologs, present almost exclusively in plants belonging to the Caryophyllales. The possible function of this gene in planta was examined in transgenic Ah24 overexpressing Arabidopsis thaliana and Nicotiana tabacum plants. Transformed Arabidopsis showed enhanced vegetative growth and increased leaf number with no penalty in one fitness component, such as seed yield, in experimental conditions.

Transgenic tobacco plants, which grew and reproduced normally, had increased insect herbivory resistance. Modified vegetative growth in transgenic Arabidopsis coincided with significant changes in the expression of genes controlling phytohormone synthesis or signaling, whereas increased resistance to insect herbivory in transgenic tobacco coincided with higher jasmonic acid and proteinase inhibitor activity levels, plus the accumulation of nicotine and several other putative defense-related metabolites.

It is proposed that the primary role of the Ah24 gene in A. Transcriptomic analysis of grain amaranth Amaranthus hypochondriacus using pyrosequencing: comparison with A. Full Text Available Abstract Background Amaranthus hypochondriacus , a grain amaranth, is a C4 plant noted by its ability to tolerate stressful conditions and produce highly nutritious seeds. These possess an optimal amino acid balance and constitute a rich source of health-promoting peptides.

Although several recent studies, mostly involving subtractive hybridization strategies, have contributed to increase the relatively low number of grain amaranth expressed sequence tags ESTs, transcriptomic information of this species remains limited, particularly regarding tissue-specific and biotic stress-related genes.

Thus, a large scale transcriptome analysis was performed to generate stem- and abiotic stress-responsive gene expression profiles in grain amaranth. The average sequence length was 1, bp and bp for isotigs and contigs, respectively.

Only 5, singletons were recovered after quality control. Only 8, sequences were found to be homologous when the transcriptomes of A. Digital expression analysis identified 1, differentially expressed genes in response to at least one of four stress treatments tested.

These included several multiple-stress-inducible genes that could represent potential candidates for use in the engineering of stress-resistant plants. The transcriptomic data generated from pigmented stems shared similarity with findings reported in developing. Results: Utilizing single-molecule, real-time sequencing Pacific Biosciences and chromatin interaction mapping Hi-C to close assembly gaps and scaffold contigs, respectively, we improved our previously reported Illumina-based assembly to produce a chromosome-scale assembly with a scaffold N50 of To demonstrate the accuracy and utility of this approach, we produced physical and genetic maps and identified candidate genes for the betalain pigmentation pathway.

The genus Amaranthus comprises species which, consumed as vegetables, provide essential nutrients to man; they also have a high acceptability among the population. These two factors justify the need to increase their cultivation.

Therefore, the purpose of this research was to establish the most adequate physiological state of maturity, to harvest the leaves for human consumption. The field experiment utilized a randomized block design with three treatments and eight replications. These treatments consisted in harvesting the plants at 25, 40 and 60 days after emergence of the seedlings, samples which served to evaluate: plant height, number of leaves, leaf surface area, gross weight leaves and stems , net weight leaves , green matter and dry matter yield, as well as protein.

The chemical composition of the harvested material was evaluated also in terms of moisture, protein, crude fiber, ether extract, ash, carbohydrate, calcium, phosphorus, iron, beta-carotene and oxalates.

The results obtained in the agronomic study were subjected to analysis of variance for the respective design, with significant differences found between treatments for all the variables studied. In its turn, the results of the chemical analysis were analyzed by a completely randomized design, with significant differences obtained for most of the variables studied, except for ether extract, calcium, iron and oxalates.

From the nutritional point of view, the first harvest was the most acceptable due to the chemical composition of the plant, in particular protein It did not occur so from the agronomic point of view, since during this stage, very low yields of green matter At the second harvest, besides obtaining adequate yields of green matter 6, Full Text Available The protein profile and the amino acid composition of eleven amaranth species have been studied.

The following species were taken into account: A. Seed samples were obtained from wild populations located in the southwest of Spain. The protein profile was studied by gel filtration chromatography and denaturing electrophoresis. Profiles were similar in all taxa, with small variations in the molecular weights and amounts of the main seed proteins. Thus, after gel filtration chromatography six main fractions of around kDa, kDa, kDa, between 40 and 50 kDa, 20 and 30 kDa and below 10 kDa were observed.

The most balanced amino acid compositions were observed in the wild taxa A. These results show the potential of wild amaranthus taxa for their introduction as crops or their use in the improvement by hybridization mechanisms of other crops such as A.

Full Text Available Genome duplication event in edible dicots under the orders Rosid and Asterid, common during the oligocene period, is missing for species under the order Caryophyllales. Despite this, grain amaranths not only survived this period but display many desirable traits missing in species under rosids and asterids.

For example, grain amaranths display traits like C4 photosynthesis, high-lysine seeds, high-yield, drought resistance, tolerance to infection and resilience to stress.

It is, therefore, of interest to look for minor genome rearrangements with potential functional implications that are unique to grain amaranths. Here, by deep sequencing and assembly of 16 transcriptomes Of the protein coding de novo assembled transcripts, we have identified chimeric transcripts. Interestingly, one of the chimeric transcripts comprises two important genes, namely DHDPS1, a key enzyme implicated in the biosynthesis of lysine, and alpha-glucosidase, an enzyme involved in sucrose catabolism, in close proximity to each other separated by a distance of bases in the genome of A.

We have experimentally validated that transcripts of these two genes are also overlapping in the 3' UTR with their expression negatively correlated from bud to mature seed, suggesting a potential link between the high seed lysine trait and unique genome organization. Efectos del consumo de panes integrales elaborados con harina de Amaranthus dubius Mart. Physicochemical, functional and angiotensin converting enzyme inhibitory properties of amaranth Amaranthus hypochondriacus 7S globulin.

Amaranth 7S globulin is a minor globulin component and its impact on the properties of an amaranth protein ingredient depends on its proportion in the variety of amaranth being considered. Some physicochemical, functional and angiotesin I-converting enzyme ACE inhibitory properties of amaranth vicilin were studied in this work and compared with the 11S globulin. Fluorescence spectroscopy results indicated that 7S globulin tryptophans were more exposed to the solvent and, by calorimetry, the 7S globulin denaturation temperature T d was found lower than the 11S globulin T d , suggesting a more flexible structure.

The 7S globulin surface hydrophobicity was higher than that of the 11S globulin, which is in agreement with the better emulsifying properties of the 7S globulin. Compared with the 11S globulin, the 7S globulin presents similar ACE inhibitory activity and some functional advantages, better solubility and emulsifying activity, which suits some food requirements.
