Genome‐wide associations of leaf spectral variation in <scp>MAGIC</scp> lines of <i>Nicotiana attenuata</i>
(a water-content-related index) with loci on chromosome 1 near genes annotated as a Zeta toxin domain-containing protein, and an Exocyst subunit Exo70 family protein. While these findings are biologically plausible, they represent a very narrow subset of the spectral variation captured by HSC-PA. The HSC-PA approach supports a comprehensive understanding of the genetic determinants of leaf spectral variation that is data-driven but human-interpretable and is thus a tool to discover genetic differences underlying intraspecific variation, a foundation of biodiversity.
