Rice Variety Identification Using SSR DNA Markers

 

OMIC USA Inc. Rice Variety IdentificationRice has been a popular life-sustaining food for thousands of years. Nutritious, versatile, economical, easy to prepare and delicious – it is consumed by almost half of the world’s population. Rice is also a good source of other essential nutrients – thiamin, riboflavin, niacin, phosphorus, iron and potassium in addition to an unique source of protein. Rice protein, when compared to that of other grains, is considered one of the highest quality proteins. It has all eight of the essential amino acids, which are necessary building blocks for strong muscles. Rice contains no fat, no cholesterol and no sodium. This, along with being non-allergenic and gluten-free, makes rice especially well suited for persons with special dietary needs.

OMIC USA Inc. Rice Variety IdentificationRice plants are found in diverse growing conditions with a broad range of genetic diversity as reflected in the large number of varieties that exist today. Grown in varied regions of the globe, from the water logged plains of Bangladesh to the mountain regions of Nepal; it has successfully adapted to various climates and geography.

It is estimated that there are more than 100,000 rice varieties — some with unique characteristics and tastes like Calrose, Jasmine, and Basmati. These varieties are synonymous with premium-brand names and quality in the marketplace. Varietal adulteration with intent to gain premium-brand quality is still a delicate and challenging problem, and the need to protect the purity of these premium varieties is often a major factor in corporate business decisions.

Because we understand the economic impact of rice on Asian consumers and the high importance placed on specific rice varieties, OMIC USA, Inc. is able to offer rice identification and verification services. Our services consist of two levels of verification: initial intervention and verification of variety (Level 1), which is a qualitative screen where a positive verification of a given sample is established, and the determination of contaminant (Level 2), which is a quantitative assay to determine percent contaminant of known or unknown variety. Level 2 intervention relies on the findings of the initial variety verification. Based on statistics and the available unique set of markers, we offer two types of quantitative assay analysis options, one at forty-eight (48) kernel level and the other at ninety-six (96) kernel level; statistical enumeration and sensitivity of detection differentiates the two.

We use simple sequence repeats (SSRs) that frequently exhibit variations in the number of repeats at a locus. Because of their abundance and inherent potential for variation, SSRs have become a valuable source of genetic markers. A set of selected unique SSR markers that was developed in-house and integrated into our rice verification program can differentiate approximately the twenty five (25) Japanese and California rice varieties.

Customer samples can be drawn during any stage of the production process — from seed to export shipment stages — depending on client needs. Samples measuring 500g or greater should be submitted. Upon completion of analysis, OMIC USA Inc. will issue a "Certificate of Analysis" verifying this sample.

Certification of Variety by DNA Analysis & Identity Preservation Documentation for Japanese Packaging Labels

This option provides customers with certification intended for merit labeling purposes. It allows the name of the rice variety to be printed on consumer packaging in accordance with Japan Agricultural Standard (JAS) regulations. OMIC USA Inc. verifies the rice variety by 1) analyzing the DNA of the composite sample (of the rice to be shipped to Japan) and 2) tracing the identity of the rice from seed to export shipment by reviewing identity preservation documents provided by the shipper: Declaration of Seed Usage (Grower's Statement) and Declaration of Lot Identity Preservation (Applicant's Statement).

In the case of U.S.-grown rice, if the Declaration of Lot Identity Preservation (Applicant's Statement) is submitted with the composite sample, other documentation is not required.

This analysis is performed in conjunction with the Food Safety Inspection required by the Food Department of Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF).
