Maize Dof1 was suggested to be a regulator of the expression of the C4 photosynthetic phosphoenolpyruvate carboxylase (C4PEPC) gene [ 35].
Another study also detected sharp increase of laccase transcripts responding to lead (Pb) stress in maize, which was suggested to account in part for Pb hyperaccumulation in the line 178 [ 66].
However, these strong differences could also originate from or be enhanced by an underestimation of the effects of domestication in maize, as was suggested by Wright et al. (2005) due to the lack of polymorphism of gene fragments used in their analysis.
Moreover, Narrow sheath 1 (NS1) and Narrow sheath 2 (NS2), which are duplicated relatives of PRS in maize, have been suggested to play a role in a lateral domain of shoot apical meristems (Nardmann et al.2004).2004
Recently, a possible involvement of NO in the mediation of nitrate-dependent root growth in maize has been suggested [ 52].
In rice and maize, PSY3 expression is suggested to be strongly inducible in roots by drought and salt stress and application of ABA, since their promoter regions harbour cis-elements involved in plant response to abiotic stress [ 11, 39].
In maize, for instance, it has been suggested that association mapping should be conducted with SNP markers spaced every 100 200 bp (Tenaillon et al. 2001).
In monocots, maize 9- LOX (ZmLOX3) has been suggested to be highly involved in regulation of development and to act as a susceptibility factor [ 15, 16].
Maize and wheat lineages have been suggested to split between 50 and 80 Mya [ 34] and between 44 and 60 Mya [ 35].
For instance, involvement of the E3 SCF complex, and its relationship with AUX in the cell division process during maize kernel development, has already been suggested by Liu et al. [ 55].
