WebMay 16, 2024 · A number of methods have also been developed to infer selection and demographic change based on the complete distribution of counts of derived alleles across sites, the unfolded site frequency spectrum (uSFS) (e.g., Boyko et al. 2008; Schneider et al. 2011; Tataru et al. 2024). WebThe p660 form absorbs red light and is converted to the p73o form believed to induce a biological response. The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9.
