Phytoextraction of cadmium by Ipomoea aquatica water spinach in hydroponic solution: effects of cadmium speciation.
Phytoextraction is a promising technique to remediate heavy metals from contaminated wastewater. However, the interactions of multi-contaminants are not fully clear. This study employed cadmium, Triton X TX , and EDTA to investigate their interactions on phytotoxicity and Cd phytoextraction of Ipomoea aquatica water spinach in simulated wastewater. Statistic regression was applied to evaluate Cd speciation on Cd uptake in shoots and stems of I. Results indicated that the root length was a more sensitive parameter than root weight and shoot weight.
Both the root length and the root biomass were negatively correlated with the total soluble Cd ions. In contrast, Cd phytoextraction of I. Additionally, the high Cd bioconcentration factors of I. Kangkung is a member of Convolvulaceae plants which is popular in Indonesia.
Kangkung leaves contain of amino acid, fatty acid, minerals, and a high value of total phenolic content. Kangkung had been found with cyotoxic, antiproliferative and anti-inflammatory activities. Both are growing well on different-altitude areas. The purpose of this study was to det Ipomoea aquatica locally known as "kangkung" has previously been reported to have hypoglycemic activities on glucose level in diabetes patients.
However, the effect of I. This study provides new insights on the changes of endogenous metabolites caused by I. The results suggested 19 potential biomarkers with variable importance projections VIP above 0. From the changes in the metabolites, the affected pathways and aspects of metabolism were identified. This implies capabilities of I. However, the administration of I.

Disentangling the origins of cultivated sweet potato Ipomoea batatas L.
This hexaploid species could have had either an autopolyploid origin, from the diploid I. We generated molecular genetic data for a broad sample of cultivated sweet potatoes and its diploid and polyploid wild relatives, for noncoding chloroplast and nuclear ITS sequences, and nuclear SSRs. Our data did not support an allopolyploid origin for I.
Our data support an autopolyploid origin of sweet potato from the ancestor it shares with I. Two I. They show more divergence with each other than either does with I. We thus propose that cultivated I. Secondary contact between sweet potatoes domesticated in Central America and in South America, from differentiated wild I. Sweet potato Ipomoea batatas L. Full Text Available Abstract Background Currently there exists a limited availability of genetic marker resources in sweetpotato Ipomoea batatas, which is hindering genetic research in this species.
It is necessary to develop more molecular markers for potential use in sweetpotato genetic research. With the newly developed next generation sequencing technology, large amount of transcribed sequences of sweetpotato have been generated and are available for identifying SSR markers by data mining.
On an average, one SSR was found per 7. Based on these SSR-containing sequences, 1, pairs of high-quality SSR primers were designed and used for validation of the amplification and assessment of the polymorphism between two parents of one mapping population E Shu 3 Hao and Guang 2k and eight accessions of cultivated sweetpotatoes.
