AbstractGuar (Cyamopsis tetragonoloba) is an important industrial crop. The knowledge about genes of guar involved in various processes can help in developing improved varieties of this crop. qRT-PCR is a preferred technique for accurate quantification of gene expression data. This technique requires the use of appropriate reference genes from the crop to be studied. Such genes have not been yet identified in guar. The expression stabilities of the 10 candidate reference genes, viz., CYP, ACT 11, EF-1α, TUA, TUB, ACT 7, UBQ 10, UBC 2, GAPDH and 18S rRNA were evaluated in various tissues of guar under normal and abiotic stress conditions. Four different algorithms, geNorm, NormFinder, BestKeeper and ∆Ct approach, were used to assess the expression stabilities and the results obtained were integrated into comprehensive stability rankings. The most stable reference genes were found to be CYP and ACT 11(tissues), ACT 11, UBC 2 and ACT 7 (seed development), ACT 7 and TUB (drought stress), TUA, UBC 2 and CYP (nitrogen stress), TUA and UBC 2 (cold stress), GAPDH and ACT 7 (heat stress) and GAPDH and EF-1a (salt stress). These results indicated the necessity of identifying a suitable reference gene for each experimental condition. Four selected reference genes were validated by normalizing the expression of CtMT1 gene. To the best of our knowledge this is the first report on the identification of reference genes in guar. These findings are likely to provide a boost to the gene expression studies in this important crop.

Background and aims Persimmon (Diospyros kaki) is an economically important fruit tree species with complex flowering characteristics. To obtain accurate expression pattern analysis results, it is vital to select a reliable gene for the normalization of real-time quantitative polymerase chain reaction data. The aim of this study was to identify the optimal internal control gene among six candidate genes for gene expression analysis in different persimmon organs and developmental stages. Materials and methods This analysis was conducted using geNorm and NormFinder software to show differences in the stability of the six reference genes among tissues and floral developmental stages of the same plant. Results Although genes that exhibited moderate expression in NormFinder revealed slightly different expression stabilities than those obtained by geNorm, both sets of results showed that GAPDH was the best reference gene in different organs and floral buds at different developmental stages, whereas 18SrRNA was the least stable gene. Conclusions Based on the overall ranking, GAPDH is the most suitable reference gene and is highly recommended for gene expression studies in different organs and different developmental stages of persimmon. This study provides useful reference data for future gene expression studies and will contribute to improving the accuracy of gene expression results in persimmon.

Quantitative real-time polymerase chain reaction (qRT-PCR) is one of the most common methods for gene expression studies. Data normalization based on reference genes is essential for qRT-PCR assays. This study identifies suitable reference genes for local chilli, Capsicum annuum var MC11 under incident of Cucumber mosaic virus infection. Six candidate genes actin, tub, EF1α, GAPDH, TEF1α and 18SrRNA and three validated Capsicum reference genes UBI-3 ref, β-tub ref and gapdhref were tested against five chilli plant parts stem, shoot, leave, flower and root.  The PCR/qRT-PCR results demonstrate only five candidate references genes actin, EF1α, GAPDH, 18SrRNA, and TEF1α that show specific single band of amplicon, without primer dimers and at the targeted sizes. Through qRT-PCR, GAPDH gives single peak in dissociation curve in all plant parts used further fulfilling the characteristic of reference genes.Previous work on validation of reference genes in pepper shows that only UBI-3 suits to C. annuum var MC11 infected CMV, thus we suggest that GAPDH has a potential to be a validated reference gene for C. annuum var MC11 and can be used together UBI-3 for the purpose of data normalization.
