Most of N. crassa mutant list is adapted from Bell-Pedersen (20).
*Period at 25°C, unless otherwise indicated. A range of period is given when there are variations of period from different sources.
^†Values of Q₁₀ are given when they are available from literature or if there are data points that allow us to calculate Q ₁₀ = (T ₂/T ₁)^{10/(θ¹−θ²)} (43). A range of Q ₁₀ is given when there are different values of Q ₁₀ from different sources. Matsumoto et al. (22) use two different values of Q₁₀, below and above 24°C. If a value of Q ₁₀ is not available, simple “Yes” or “No” is used to represent either presence or absence of temperature compensation in N. crassa where Bell-Pedersen (20) used “+” or “−” to represent the data. “Yes” indicates that the period changes are <20% over a 10°C range in temperature.
