چکیده
Lignin is a complex and heterogeneous phenolice polymer comprising of monolignols, namely guaiacyl, syringyl and p-hydroxyphenyl [1]. Lignin cross-links with other polysacharids in secondary cell wall for hardening the corresponding structure and improving the resilience of plant against both biotic and abiotic stresses [2,3].Phenylalanine ammonia lyase (PAL) is the first enzyme in phenylpropanoeid pathway [4], catalyzing the conversion of L-phenylalanine to cinammic acid and ammonia were carried out [2,5]. Here Comparative coexpressed network study of PAL in Brachypodium distachyon and Glycine max were carried out. Gene coexpression network (GCN) for PAL genes were predicted via PlaNet and Phytozome for B. distachyon and Phytozome for Glycine max. Plantpan 2.0 was implemented to look for the co-occurrence of transcription factor binding sites (TFBSs) in the promoter sequences of the coexpressed genes to further confirm what was obtained in GCN. GCN analyses revealed that there are 33 and 27 genes in 6 sub-networks for G. max and B. distachyon, respectively. Our results were definitively led to the identification of some more genes in addition to what was characterized earlier [1,2]. Analyses of upstream sequences of the genes ORFs via plantpan 2.0 were revealed many co-occurred TFBSs in each sub-network, and common co-occurrence TFBS between sub-networks in each plant. Interestingly, some TFBSs were common between some sub-networks of the two plants that were examined.کلیدواژه ها
