Availability of maize genomic library?

[yuling meng]

Dear Sir/Madam,
      We are interested in the development of maize root, especially in
the regulation of some genes expression, but there is no clone
available, therefore we plan to get them by screening genomic
library, wether  would you provide genomic library or tell us where
we could get it? we  appreciate your help.
Looking forward to hearing from you.

With best regards

Sincerely yours
Yuling MENG
