Twl is essential for proper conidiation in <i>M</i>. <i>oryzae</i>, likely by integrating nutrient homeostasis with phototropism.

<p>(A) Microscopic analyses of conidiating structures from wild type or <i>twl</i>Δ mutant. Images were taken 24 h post photo-induction. Scale bar = 10 micron. (B) Bar chart depicting quantitatively assessed conidiation in wild type and <i>twl</i>Δ. Mean values (±SE) presented as total number of conidia were derived from three independent experiments (n = 30 colonies for each sample). Assessments were performed 2 days post induction. (C) Bar chart depicting quantitative assessment of conidiation in wild type or the <i>twl</i>Δ supplemented with 1% or 4% rice or barley extract. (D) Bar chart depicting quantitative assessment of conidiation in wild type or the <i>twl</i>Δ supplemented with 1% rice extract from dark-grown (for 3 days) or light-grown CO39 seedlings.
