Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Genetic purity of seeds is one of the critical aspects in the seed industry. Molecular seed testing laboratories are utilizing PCR based diagnostic tools for genetic purity analysis. High quality DNA is an essential prerequisite for such analyses. Here, we demonstrate a robust and inexpensive DNA extraction method to isolate genomic DNA from variety of crops. Current method (M2) was compared with four commonly used DNA isolation methods for PCR-based genetic characterization and High Resolution Melt (HRM) based hybridity analysis of cotton, okra, tomato and maize using SSR markers. DNA extracted through current method showed excellent yield and quality as compared to other methods. High quality, PCR ready DNA was isolated within 30–50 min and displayed best results for genetic purity analysis using HRM. In contrast, several genomic DNA samples extracted using other methods were found unsuitable for HRM analysis. Our method can be a perfect choice in seed industry, where thousands of samples are processed every day. Notably, using our method single technician can extract DNA from 96 leaf samples within 30–50 min, at a cost of only $0.11/sample. Overall, current DNA extraction method is a reliable and cost-effective solution for large-scale genotyping experiments in the agricultural industry.
