| Abstract | Quantitative PCR (qPCR) is a robust technology for comparing the expression profiles of target genes, however the data produced need normalization with appropriate reference genes. The purpose of this study was to evaluate the expression stability of eight candidate reference genes (EF1A 1a1, EF1A 2a, EF1A 2b, EF1B, ACT11, UKN 1, ACT and SKIP 16) for qPCR assays in soybean leaves under fungus (Cercospora kikuchii) infection and treatments with salicylic and jasmonic acids. Four programs, GeNorm, NormFinder, BestKeeper, and RefFinder were used to evaluate the expression stability. The leaves were treated according the following conditions: 1) infected with Cercospora kikuchii (CK); (2) treated with salicylic acid (SA); (3) treated with SA and infected with C. kikuchii; (4) treated with jasmonic acid (JA); and (5) treated with JA and infected with C. kikuchii. For all studied conditions, GeNorm analyses revealed that combinations of six genes were always needed for gene expression normalization. Three EF1A genes (EF1A 2a, EF1A 1a1 and EF1A 2b) were the most stable in all tested conditions and then, they were always included in gene combinations. The other three genes varied according the different conditions. In analyses with other programs, at least two EF1A genes were often ranked among the three best stable genes. The expression of a PR3 (class I chitinase) gene was used to validate the reference genes across the total samples. Our results provide a shortlist of reference genes to normalize qPCR assays in soybean under CK infection and treatments with SA and JA. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
