A team from Cold Spring Harbor Laboratory has successfully employed CRISPR technology to enhance the growth of goldenberries (Physalis peruviana), a nutrient-rich fruit primarily cultivated in South America. Traditionally, goldenberry plants are sprawling and cumbersome, limiting their agricultural potential. Colombia leads in production, with additional cultivation in Peru, Ecuador, South Africa, and India, yet the underutilization of this crop persists due to its challenging growth characteristics.
By targeting the classical stem length regulator ERECTA through genome-editing techniques, researchers have engineered a more compact plant architecture. This advancement not only facilitates easier planting and maintenance but also positions goldenberries as a viable option for large-scale farming. The implications of this breakthrough extend beyond mere agricultural efficiency; they could pave the way for developing crops that are more resilient to diseases, pests, and climate change.
Published in Plants People Planet, the research underscores the potential of CRISPR to revolutionize food production amid growing global demands. As highlighted by Blaine Fitzgerald from the Lippman lab, innovations in agricultural practices are crucial in addressing the challenges posed by climate change and population growth. The team is now focused on further refining these varieties to enhance desirable traits and secure regulatory approvals, marking a significant step towards commercial cultivation.
