| sequencing and de novo assembly of the complete chloroplast genome of the peruvian carrot (arracacia xanthorrhiza bancroft). | arracacia xanthorrhiza is an important secondary food crop in south america and puerto rico. the lack of crop protection and improvement strategies leads to infections damaging the storage roots. here, we report the annotated complete chloroplast genome sequence of a. xanthorrhiza as a step toward developing genomic resources for this crop. | 2017 | 28209812 |

| chemical, physical and morphometric properties of peruvian carrot (arracacia xanthorrhiza b.) starch. | starch was isolated from peruvian carrot (pc)--or arracacha--(arraccacia xanthorrhiza b.) roots. its chemical, physical, physicochemical and granular structural properties were compared to those of commercial cassava starch. scanning electron microscopy revealed a granular size for pc starch ranging between 4 and 26 microns in diameter, with spherical and truncated-egg shapes. pc and cassava starches were similar regarding gross chemical composition and basic physical characteristics but differe ... | 1999 | 10974715 |
| structural characterization of peruvian carrot (arracacia xanthorrhiza) starch and the effect of annealing on its semicrystalline structure. | structural characteristics of native and annealed peruvian carrot (arracacia xanthorrhiza) starches were determined and compared to those of cassava and potato starches. peruvian carrot starch presented round and irregular shaped granules, low amylose content and b-type x-ray pattern. amylopectin of this starch contained a large proportion of long (dp > 37) and short (dp 6-12) branched chains. these last ones may contribute to its low gelatinization temperature. after annealing, the gelatinizati ... | 2011 | 21410256 |
| impact of cooking and drying on the phenolic, carotenoid contents and in vitro antioxidant capacity of andean arracacha (arracacia xanthorrhiza bancr.) root. | the influence of different cooking regimes such as boiling, oven, microwave and hot-air drying on the retention of total phenolics (tp), total carotenoids (tc) and in vitro antioxidant capacity (ac) for three colored arracacha roots was studied. continuous losses of tp, tc and ac during the course of the different cooking processes were observed. boiling at 99.5° c for 20 min turned to be the best method to cook this root due to a high retention of tp, tc and ac in comparison to oven cooking at ... | 2011 | 21813594 |
| a novel vitivirus-like sequence found in arracacia xanthorrhiza plants by high throughput sequencing. | high throughput sequencing (hts) is a very powerful tool for detecting and discovering novel viral-like sequences without prior knowledge of the sequence. here we describe the complete genome of a new vitivirus-like sequence that was found in arracacha (arracacia xanthorrhiza) plants using hts technology. the complete genome sequence was validated by sanger sequencing. the genomic organization of the new putative vitivirus resembles that of grapevine virus b (gvb) and grapevine virus d (gvd). th ... | 2017 | 28316018 |
| complete genome sequence of arracacha mottle virus. | arracacha mottle virus (amov) is the only potyvirus reported to infect arracacha (arracacia xanthorrhiza) in brazil. here, the complete genome sequence of an isolate of amov was determined to be 9,630 nucleotides in length, excluding the 3' poly-a tail, and encoding a polyprotein of 3,135 amino acids and a putative p3n-pipo protein. its genomic organization is typical of a member of the genus potyvirus, containing all conserved motifs. its full genome sequence shared 56.2 % nucleotide identity w ... | 2013 | 23001696 |
| characterization of a member of a new potyvirus species infecting arracacha in brazil. | an arracacha (arracacia xanthorrhiza) plant collected in brazil was found to be infected by a new virus. this viral isolate (named c17) systemically infected nicotiana benthamiana and apium graveolens. a polyclonal antibody was raised, and analysis of our arracacha germplasm collection showed a high infection rate of c17-like viruses (93% infection). sequencing of the ca. 1.7 kb 3'-terminal genomic region revealed a typical potyvirus genome organization. it shared less than 70% nucleotide identi ... | 2009 | 19109690 |
