WebMar 9, 2024 · One understudied opportunity is using feral crops—plants that have escaped and persisted without cultivation—as a source of genetic diversity, which could build resilience in domesticated conspecifics. In some cases, however, feral plants vigorously compete with crops as weeds, challenging food security. WebThe observed extra- ordinary diversity in the pigment composition (based on ten carotenoids, five po- lar- and three non-polar chlorophyll types) appeared closely related to current tax- onomy and published phylogeny. Chl a and the accessory pigments MgDVP, Chl c2, Ddx, Dtx and β,β-carotene comprised the common haptophyte pigment load.
