Identification and expression analysis of putative arabidopsis orthologue AGP genes of Quercus suber. (A) NJ tree based on 19 AGP amino acid sequences of A. thaliana and Q. suber. The proteins were named according to their gene name/EST in the Cork Oak or TAIR database (accession numbers in Table 1). The length of the branches refers to the amino acid variation rates. Numbers indicate the percentage of 1000 bootstrap re-samplings that support the inferred topology. The scale bar is an indicator of genetic distance based on branch length. (B) Relative expression of Q. suber AGP genes measured by real-time RT-PCR, and normalized to QsPP2AA3 and QsUBQ, using RNA from male or female flower tissues. Error bars indicate standard deviation (s.d.). Female, cDNA pool; male, masculine cDNA pool.
