Abstract:
Craterostigma plantagineum is a desiccation tolerant resurrection plant. Many genes are induced during desiccation. Dehydrins are a group of dehydration-induced genes present in all higher plants. The current study aims at classifying the most abundantly expressed dehydrin genes from vegetative tissues of C. plantagineum and quantifying their expression. To identify variations between dehydrin isoforms at different stages of desiccation and rehydration by RT-qPCR, the target mRNA requires an accurate and reliable normalization. Previously we reported that RNAs from leaves and roots of C. plantagineum are not degraded during desiccation and subsequent rehydration thus allowing the use of RT-qPCR to test the stability of reference genes. The expression stability of eight candidate reference genes was tested in leaves, roots and callus. These genes were ranked according to their stability of gene expression using GeNorm(PLUS) and RefFinder. The most consistently expressed reference genes in each tissue were identified and used to normalize gene expression data. Dehydrin isoforms were divided in three groups based on the expression level during the desiccation process in three different tissues (leaves, roots and callus).

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
