I have a hash, where hash keys (taxon) point to an array of values (genes). For example: 
my %gg = ('1567' => ['NP_011', 'NP_012', 'NP_013'], '2000'=> ['NP_020'
+, 'NP_021', 'NP_024', 'NP_025', 'NP_035']);

I want to retrieve the taxon for a given gene. For example, when I search based on NP_012 gene, I want to get the taxon 1567 and so on. Is there a way I can do this?

Thanks!
