Identification and Characterization of Cross-Species Longevity Network Module.
(A) Regulatory gene network with nodes representing both Arabidopsis and M. truncatula homologs that are coregulated in relation to longevity.
(B) Genes of colored nodes in (A) were functionally analyzed for longevity phenotype by comparing germination after 25 d of aging between mutant and wild-type seeds. The dashed line corresponds to the germination percentage of freshly harvested, non-aged seeds. The asterisk indicates a significant difference from the wild-type Col-0 seeds (χ2 test, P < 0.001).
(C) to (F) Genes with overrepresented cis-elements in M. truncatula (blue) and Arabidopsis (yellow) promoters; (C) response to auxin stimulus, (D) light regulated, (E) defense response to pathogen, and (F) SURE, sucrose binding element.
