Figure 4. Genetic and environmental robustness QTLs in Arabidopsis.

Figure 4

a. A GR QTL for seed germination timing [25] maps to chromosome 4. The QTL is specific to one environment (light + paclobutrazol [PB]), and there is no co-localized ER QTL. b. ER QTLs for two (highly correlated) traits, rosette leaf number (RLN) and total leaf number (TLN) [26], map to chromosome 5. There is no co-localized GR QTL. c. An ER QTL for cauline leaf number (CLN) [27] in short days (“micro-ER”) is located on chromosome 5. This co-localizes with a macro-ER QTL for CLN, but not with any GR QTL. The figure begins at ∼32 cM into chromosome 5 because to the left of this position are two QTL for trait means, and thus these regions are not considered for ER or GR QTL mapping.
