Table 1 Effect of sucrose on survival of wild-type and sco mutants. On 0.5-strength MS media supplemented with 2% sucrose, wild-type, sco1-1, and sco1-4 seedlings have comparable survival rates. In the absence of sucrose, less than 20% of the sco1-1 seedlings were able to produce true leaves and survive into adulthood, and no sco1-4 seedlings survived. Typically, the sco1-1 mutant seedlings that survived to adulthood in the absence of a supplemental carbon source were ones that had larger patches of green cells in their cotyledons and hypocotyls
