Leaf development, especially in leafy greens, is crucial for crop productivity. In various plants, DA1, a pivotal ubiquitin receptor that negatively regulates leaf growth, and EOD1 (ENHANCER1 OF DA1), an E3 ubiquitin ligases that interacts with DA1 through its RING domain, influence organ size. In this disclosure, in lettuce (Lactuca sativa), homologs genes were identified for both DA1 and EOD1, and da1 single mutants, da1 / eod1 double mutants, and DA1 overexpressing lines (DA1ox) were created. The da1 / eod1 double mutant exhibited a striking phenotype with larger organ size, accelerated growth, and increased biomass, resulting in higher yields and rapid growth traits pivotal for Controlled Environment Agriculture (CEA). Additionally, the da1 / eod1 double mutant displayed a pronounced ‘stay-green’ phenotype, characterized by elevated chlorophyll b levels, which implies extended shelf life, and enhanced postharvest quality, both traits indispensable for leafy vegetables in CEA settings. In contrast, the DA1ox line exhibited early senescence and diminished organ size. Based on these findings that spotlight the nuanced roles of the DA1-EOD1 module in modulating plant growth phases and its potential to revolutionize breeding strategies for improved yield and postharvest longevity in CEA-cultivated leafy greens, this disclosure provides guide RNAs for gene editing of DA1 and EOD1, and transformed lettuce having improved organ size and postharvest quality.
