From: Identification and characterization of the TCA cycle genes in maize
Phylogeny and expression analysis of the TCA cycle genes among maize (Zea mays), Arabidopsis (Arabidopsis thaliana) and tomato (Solanum lycopersicum). Each phylogenetic tree was constructed by MEGA5.0 using the neighbour-joining method with 1000 bootstrap values, and the phylogenetic tree of the SDH proteins was constructed by the maximum likelihood estimate method. The gene expression data were downloaded from TRAVA (http://travadb.org/, Arabidopsis), Tomexpress (http://tomexpress.toulouse.inra.fr/, tomato), and qTeller (www.qteller.com, maize). The expression characteristics of each gene were evaluated by the Z-score
