Identification of differential proteins in cassava cultivar NZ199 leaves from autotetraploid and diploid genotypes.

The spots showing differential expression (>2.0-fold of the normalized volume) were counted after gel analysis and manual editing with Delta2D software. Each value represents the mean ± SE of triplicates. Protein spots whose abundance increased (+) or decreased (−) after polyploidy were shown. The numbers corresponded to the 2-DE gel in Fig. 2. a. The numbers corresponded to the 2-DE gel in Fig. 2–3. b, Expression change level in tetraploid genotype compared with diploid genotype, c, NCBI accession number. d, Probability-based MOWSE (molecular weight search) scores. e, The number of unique peptides identified by MS/MS, and individual ions scores are all identity or extensive homology (p<0.05).
