AM-induced M. truncatula genes related to cell wall degradation and modification

Genes activated more than 2-fold in both AM interactions are sorted according to the induction level in G. mosseae-colonized roots. Oligo ID, Identifier of M. truncatula 70-mer oligonucleotides. TIGR ID, Identifier in the TIGR M. truncatula Gene Index. Annotation, Updated annotations according to blast 2x hits in PIR and TrEMBL databases as well as Interpro searches. FC, Functional categories as defined by Journet et al. (2002) and in Figure 1. GM and GI, log2 expression ratios in G. mosseae- and G. intraradices-colonized roots. E-Northern, Expression profiles from the TIGR M. truncatula Gene Index. Myc-specific, TIGR TC is exclusively composed of ESTs from AM roots; Myc-induced, TIGR TC is predominantly composed of ESTs from AM roots; Sym-induced, TIGR TC is predominantly composed of ESTs from root nodules, nodulated roots and AM roots; Myc-expressed, TIGR TC is composed of at least one EST from AM roots. Literature, Found to be AM induced in other expression profiling studies; M, Manthey et al. (2004).
