We aimed at finding and validating a stable reference gene in Camellia sinensis and Camellia assamica from a set of four putative housekeeping genes in various samples exposed to different experimental conditions mainly biotic and abiotic stresses. Variation in gene expression across Camellia sinensis leaf tissues exposed to nine different kind of experimental sets was studied. The suitability of 18S rRNA, 26s rRNA, rubisco bis phosphatase (RuBP) and camellia actin (Act) as reference genes were validated by geNorm and BestKeeper programs and revealed 18S rRNA and RuBP to be the most stably expressing housekeeping gene. We therefore recommend use of RuBP as a stable reference gene for normalisation of transcripts abundance experiments in tea leaf samples.
