Fig. 4From: Root iTRAQ protein profile analysis of two Citrus species differing in aluminum-tolerance in response to long-term aluminum-toxicityAl-induced changes in S metabolism in C. sinensis and C. grandis roots. Up-regulated proteins presented in + Al C. sinensis and C. grandis (only in C. sinensis) roots were labeled in red (blue).
