Good job, Jess! The paper entitled "Effect of mycorrhizal colonization and light limitation on growth and reproduction of lima bean (Phaseolus lunatus L.)" becomes the most read article from the Journal of Applied Botany and Food Quality (issue 86, 2013) with a total of 1846 full text downloads. - August 2014. 

Congratulations to Brett Younginger! Brett is an invited speaker at this years ISCE meeting in Champaign-Urbana.
