Directed evolution is an engineering method that improves biological tool performance by iteratively selecting functional protein variants. In the cited split fluorescent protein study, it was demonstrated as one of two approaches used to improve split fluorescent proteins, contributing to brighter split sfCherry3 variants.

Methods
The gene-pyramiding approach is an insect resistance management strategy used in the U.S. to combat the evolution of insect resistance to Bt crops. The supplied evidence identifies it as one of the two main IRM strategies alongside the high dose/refuge approach, but does not provide further mechanistic detail.

PACE (Phage Assisted Continuous Evolution) is an engineering method used in this study to evolve cryptochrome properties. In the cited work, it was applied to increase the dynamic range of the blue-light-dependent interaction between Arabidopsis thaliana CRY2 and BIC1.
Time-resolved vibrational spectroscopy coupled with isotope labeling is an assay method used to resolve light-triggered structural dynamics in the Avena sativa LOV2 (AsLOV2) photosensory domain. In the cited study, it mapped structural evolution from 100 fs to 1 ms after optical excitation and supported a sequential allosteric model linking the flavin pocket to Jα-helix unfolding.
