    9、7622:2015(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject

    10、for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) o

    11、n all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be note

    12、d. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying

    13、any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

    16、uality markers, which are able to provide reproducible data using a variety of equipment, chemistries, and reagents. Accordingly, this Technical Report only addresses specific amplification methods for sunflower. The aims of this Technical Report are to provide a list of simple sequence repeat (SSR)

    17、 markers and methods of analysis for sunflower. The set of SSR markers was established based on expert advice from molecular biologists using lists of publicly-available markers (for ORS markers: Tang et al., 2002: TAG 105:1124-1136 and for SSL markers: GIE Cartisol Paris France), and then validated

    18、 through an intralaboratory study at GEVES (Laboratoire BioGEVES, Domaine du Magneraud, CS40052, 17700 SURGERES). The method is applied in officially testing hybrid conformity as part of the process of registering sunflower varieties in the French national varieties catalogue. This document is linke

    19、d to ISO 13495 where the different steps towards method validation are listed, and acceptance criteria are defined. ISO 2015 All rights reserved v PD ISO/TR 17622:2015 Molecular biomarker analysis SSR analysis of sunflower 1 Scope The methods and SSR markers included in this Technical Report can be

    20、used for testing hybrid conformity and other applications such as molecular fingerprinting of varieties and checking variety identity. 2 Principle SSR analysis is based on the amplification and visualization of the polymorphism caused by variation in the number of repeats in a sequence motif that is

    21、 two to five base-pairs in length, also known as a microsatellite. SSR analysis consists of the following steps: sample preparation, DNA extraction, PCR amplification, separation and detection of the PCR products. 3 Consumables and equipment 96-well or 384-well microplate PCR reagents (DNA polymeras

    23、sample, either individual seeds or seed mixes depending on the context are ground using a suitable mill (such as an IKA A10 or a Retsch MM301 1) ). 1) IKA A10 and Retsch MM301 are examples of suitable products available commercially.
