Transcriptomic comparison between nickel hyperaccumulator and non-accumulator plant species from the Geissois genus (Cunoniaceae) endemic from New Caledonia
The leaf transcriptome of the nickel hyperaccumulator Geissois pruinosa (Rubiaceae) endemic from New Caledonia was compared to the closely related non-accumulator Geissois racemosa, living respectively in serpentine maquis or rainforest on limestone, to identity differentially expressed genes potentially involved in Ni hyperaccumulation. Overall design: Leaves from 3 independant individual plants of Geissois pruinosa and Geissois racemosa were collected in their natural environment. RNA of the 6 independant samples were extracted and sequenced using the Illumina paired-end sequencing technology. Reads from one individual plant per species were assembled de novo to generate transcriptome sequences. The transcriptome of G. pruinosa was used as a reference to compare the expression of genes in both species.
