“…Consequently, our results highlighted the positive correlation between starch accumulation and dry matter content. Similar correlations were recorded by (Islam et al, 2022;Tong et al, 2023). In addition, dry matter content is genotype dependent (Scavo et al, 2023), which may explain variation in dry matter content by the genetic variations associated with somaclonal variation.…”

T HIS STUDY aimed to establish functional SSR markers corresponding to variations in starch accumulation in potato somaclones. In addition to the original cultivar Lady Rosetta, fourteen callus-sourced somaclones were investigated for their starch and sugar contents as well as dry matter content. Of the selected somaclones, one represented clones with the same starch content of the original cultivar and another represented those of lower starch content. The remaining somaclones have higher starch content, compared with original cultivar. The combined results of two growing seasons unveiled significant positive correlation between dry matter content and starch content which was absent when replacing starch with soluble sugars. Insignificant correlations were recorded between sugar content and starch content. Based on the transferability of SSR markers between species, six SSR primers characterizing variation in starch accumulation in sweet potatoes were exploited to assess genetic diversity among the selected potato clones. The analysis generated distinct and reproducible banding patterns with 68 bands, of which 62 were polymorphic. The utilized primers reflected high resolving power appeared in PIC of 0.457 in average and amplification of 44 unique bands, distributed in all studied clones except one of those containing higher starch content, compared with the original cultivar. This fingerprint is a prerequisite for recruiting clones with distinguished starch accumulation potential, addressed in the present study, in breeding programs targeting the improvement of starch accumulation in potato tubers. On the other hand, the utilized primers failed to establish phylogenetic relationship corresponding to starch content of the addressed clones. This may be attributed to utilization of few primers that did not cover a considerable proportion of the addressed genome.

“…Starch is the major component of potato tubers and is responsible for 15-20% of their fresh weight (Bertoft & Blennow, 2016;Tong et al, 2023). Consequently, our results highlighted the positive correlation between starch accumulation and dry matter content.…”

Within the realm of archaeology, the analysis of biomolecules assumes significant importance in elucidating historical dietary patterns and their implications for contemporary contexts. To achieve this, knowledge and tools of both chemistry and archaeology are essential to yield objective outcomes and conduct analyses of archaeological materials for the detection of biomolecules. Usually, only minuscule remnants of ceramic fragments are retrieved from excavations, which limits the feasibility of comprehensive laboratory analysis. This study aimed to establish a protocol for analyzing fatty acids and starch from archaeological food utensils with minimal sample quantities. Various experiments were conducted to replicate preparations that might have occurred in archaeological vessels, aiming to establish the optimal protocol. The analyses were performed using clay griddles, subjecting vegetable oil to varying temperatures for fatty acid assessment. For starch analysis, a series of experiments encompassed diverse forms of potato preparations (pulp, chuño, tortilla, carbonization, and freeze-drying) and maize (flour, tortilla, and carbonization). The verification of the experiments was confirmed by conducting identical analyses, as developed in the current study, on authentic archaeological fragments. The principal outcomes of this investigation include the successful extraction of both types of biomolecules using only 0.25 g of the sample, obtained through direct scraping from the vessel. Soxhlet extraction was identified as the most efficient strategy to recover fatty acids. Additionally, a comprehensive protocol for the identification of starch extraction was developed. This study has, for the first time, elucidated two detailed methodologies for the extraction of fatty acids and starch in scenarios in which researchers can obtain limited quantities of archaeological food utensil fragments.

“…For example, the amylose procured from potato starch typically has an average chain of 270 glycosyl units. 61 Generally, the glucose ring has a length of 0.8 nm, while Au 0 has a radius of 0.146 nm. A typical maltose unit has 8 OH groups, with each glucose ring having two OH groups (total 4 OH) in opposite planes.…”

Concentration of α-amylase in blood serum is one of the very important parameters to measure for the early-stage detection of various pancreatic disorders. Since this enzyme is present in a very small quantity in the serum, it requires the development of an ultrasensitive sensing platform for an accurate quantification with a very lower limit of detection. The study reports the development of a nanobiosensor using 'green' biosynthesis protocol wherein an in situ reduction of gold ions on a starch template yields a nanocluster resembling the shapes of serpents − AuNS. The as-synthesized serpentine AuNS demonstrates superior reaction rate kinetics when exposed to a solution loaded with the enzyme α-amylase to engender rapid starch digestion. Importantly, the enzymatic degradation of the surfacebound starch on AuNS exposes the electrically conducting gold nanoclusters, which eventually leads to a significant enhancement of the electrical conductance of the substrate. Subsequently, the large differences in the electrical conductance before and after the addition of α-amylase have been translated into an electrochemical sensor to quantitatively determine the α-amylase levels in human serum. The proposed sensor yields linear responses in the relevant physiological range of α-amylase levels (12−120 U/L) with a significantly lower limit of detection (LoD) of 6 U/L. This sensor exhibits high analytical sensitivity (0.03 (U/L) −1 ) and exceptional specificity with a rapid response time. The results obtained from the laboratory scale prototype have been validated against the results obtained from the clinical autoanalyzer to assess the accuracy. The nanobiosensor has shown a significant potential to translate into a portable, rapid, ultrasensitive, specific, and affordable point-of-care-testing device for the diagnosis of pancreatic disorders at the patients' site.
