Remove punctuation (comma) after year

Question

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.

Answer 1

It might depends on the specific style used, but for standard biblatex authoryear style, one should be able to remove the punctuation after the year with

\renewcommand{\labelnamepunct}{\addspace}

and to prevent the journal title to be printed in italics, the following should do the trick

\DeclareFieldFormat{journaltitle}{#1}
