# Remove punctuation (comma) after year

For American Society of Genetics journal (Genetics), the bibliography format is somewhat strange. It requires no parenthesis or comma after year field.

Beadle, G. B. et al. 2009 Title of the paper. Non-Italic-Name-of-Journal 88: 203-209

I am getting: Beadle, G. B. et al. 2009. Title.... And the journal name is printing in italics.

Can someone help me with getting rid of the period after the 'year' field and removing the italicized Journal font?

Edit1: I am using biblatex with authoryear style and natbib=true.

Welcome to TeX.SE! Could you edit your question to provide a hyperlink to the bibliography style file, or at least the name of this file? Thanks. –  Mico Jan 28 '13 at 8:17
@Mico One of the tags is biblatex, so more than the style we need the biblatex options (including the style) –  Guido Jan 28 '13 at 10:28
