Conidial number data

<p>The number of asexual spores (conidia) per mm<sup>2</sup> produced by A. <em>nidulans</em> strains MH2 (<em>xpr</em>G<sup>+</sup>), MK422 (<em>xpr</em>GΔ) and MK85 (<em>xpr</em>G1) was determined by removing three plugs from colonies on complete medium containing 2.2% agar. The conidia from each plug were suspended in a solution of 0.01% TWEEN80 and counted in a haemocytometer. The experiment was repeated a total of four times using different batches of medium.</p>
